Plug-In Unit Warnings

Many plug-in units are stamped with anti-electrostatic markings (see figures at left) and require special handling and storage. The following precautions should be strictly observed to avoid damage from electrostatic discharge (ESD).

• When handling plug-in units for installation, removal, or option setting, always wear a wrist strap, with a minimum 1-megohm resistance, that is connected to safety ground.

• Hold only the edges of the plug-in units. Do not touch the integrated circuit (IC) leads or the circuitry.

• Transport and store the plug-in units in the ESD protective bags that the units were shipped in. Always fold the open end of the bag and secure it with ESD tape.

• Return the units to Fujitsu in ESD protective bags. Use the original shipping containers when possible.

All plug-in units should be seated with a slow, firm motion. Many critical units have longer power connector pins to minimize power surges during installation. A slow insertion method ensures that the plug-in units are not damaged.

Fiber Warnings

Danger: Invisible laser radiation. Avoid direct exposure to the beam. Never look into the end of a fiber, fiber cord, or fiber pigtail. Permanent eye damage or blindness can occur quickly when laser radiation is present. The label on the left is attached to laser-emitting and receiving units as a reminder. Use of controls, adjustments, or procedures other than those specified may result in hazardous laser radiation exposure from a fiber-optic pigtail.

Danger: Never handle exposed fiber with your bare hands or touch it to your body. Fiber fragments can enter the skin and are difficult to detect and remove.

Installation Restriction

Systems shall be installed only in restricted access areas (for example, dedicated equipment rooms or equipment closets) in accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical Code, ANSI/NFPA 70.

2 Alarm and Orderwire (AW1A) Unit

2.1 General

This section describes the functions of the following units used in the FLM 150 ADM:

• Alarm–Basic (AW1A-BSC)

• Alarm and Orderwire–Enhanced (AW1A-ENH)

The AW1A unit contains the office alarm output function. It provides the office alarm outputs from the FLM 150 ADM Shelf to the external alarm devices and the alarm/status LEDs that show local or remote shelf conditions. The unit can be used in all FLM 150 ADM configurations.

2.2 Features

Table 2-1 lists the AW1A unit(s) and associated supported features.

Table 2-1: AW1A Units and Associated Supported Features

2.3 Functional Description

The AW1A unit provides relay contact closures to operate the bay alarm lights and local alarm ACO functions. These relays supply ground or loop current to alarm equipment. The audible and visual alarm severities are CR, MJ, and MN.

The AW1A unit receives instructions from the Microprocessor (MP1A-xxx) unit to produce front-panel LED and office alarm indications.

The AW1A unit can be set to monitor alarms at a far-end site by selecting the assigned equipment number of the far end using the FE SEL (far end select) button on the MP1A unit. When the alarms shown on the AW1A unit refer to alarms at some other network element, the far-end activity LED is lit. When the alarms shown on the AW1A unit refer to alarms at the local shelf, the near-end activity LED is lit.

The AW1A-ENH unit provides connections for up to 16 housekeeping alarms and up to 4 housekeeping controls. It also provides orderwire for both 2- and 4-wire applications.

Figure 2-1 is a block diagram of the AW1A-ENH alarm and housekeeping functions. Figure 2-2 is a block diagram of the AW1A-ENH orderwire function.

2.4 Options

Hardware Options

These straps set the alarm severity of visual, audible, and LED alarms to be generated if both power units fail. Setting the appropriate switch to MJ (VMJ, AMJ, LEDMJ) generates a corresponding major alarm. Setting the appropriate switch to CR (VCR, ACR, LED CR) generates a corresponding critical alarm. The default setting for each type of alarm is CR.

The AW1A-ENH unit also has a switch that controls the optional audible and visual minor office alarm generated by incoming calls on the orderwire channel. If a minor alarm indication is required to indicate incoming calls, enable this feature by setting the switch to CMN EN (call minor enable). If a minor alarm indication for incoming calls is not required, set this switch to CMN DIS (call minor disable).

The AW1A unit provides the capability to set options for near- and far-end failure alarms. The ALM connector on the backplane connects these alarms to the office alarm grid. These alarms are controlled by Form A relays that can be wired for closed contact (ground) or open contact (high impedance) alarming. The AW1A outputs the following alarms interfaced through the backplane:

• Audible

- AUD CR—audible critical

- AUD MJ—audible major

- AUD MN—audible minor

• Visual

- VIS CR—visual critical

- VIS MJ—visual major

- VIS MN—visual minor

• AC PWR MN—power failure minor (AW1A-ENH only)

Housekeeping Alarms

The housekeeping alarm and control functions allow the FLM 150 ADM to gather external equipment alarms from the remote terminal sites and display them at the central office (CO). Control relays are provided to allow the CO to turn on remote equipment such as air conditioners or power generators.

The FLM 150 ADM provides for up to 16 internal and external alarm points, as well as four outgoing-only control relays. All alarm/control ports are bidirectional so that alarms can be input to the system and simultaneously transmitted to external equipment or surveillance equipment.

The alarm type and severity for each port can be provisioned through the craft interface. Control ports can be operated locally or remotely using the craft interface. Unused alarm or control ports should be disabled. The control relays can only be operated using TL1 commands.

Housekeeping interface specifications are listed in Tables 2-4 and 2-5.

2.9 Orderwire Interface

The 2-wire telephone function interfaces through a phone jack located on the front panel of the unit. The 4-wire extension function interfaces through backplane connectors CN 7 and CN 8. Two connectors are provided so that data can be daisy-chained to other systems.

Orderwire data is carried in the E1 and E2 bytes of the SONET overhead. The E1 byte is designated as a local orderwire channel between adjacent network elements. The E2 byte is designated as an express channel between line-terminating NEs. The 2-wire interface on the front panel of the AW1A must be provisioned using the craft interface to access the E1 or the E2 channel. The 4-wire interface is connected to both channels.

For the 2-wire orderwire application, 3-digit numbers must be provisioned for selective calling and for the all/group call feature. These numbers are provisioned through the craft interface. The factory defaults for these parameters are selective call = 000 and all/group call = 777.

When the system is rung on the orderwire, the CALL LED on the front of the AW1A-ENH unit flashes for 90 seconds or until the call is answered, whichever comes first. If the all/group call number has been dialed, the CALL LED continues to flash for 90 seconds or until all sites have answered. An audible call signal can be connected to the orderwire through the backplane.



3: Embedded Operations Channel (EC1A) Unit

3 Embedded Operations Channel (EC1A) Unit

3.1 General

This section describes the functions of the following EC1A units as they are used in the FLM 150 ADM system:

• Embedded Operations Channel (EC1A)

• Embedded Operations Channel–Version 2 (EC1A-V2)

• Embedded Operations Channel–Software Download (EC1A-DL1)

• Embedded Operations Channel–Software Download, Version 2 (EC1A-DL2)

The EC1A unit accesses and processes the data communications channel (DCC) and the automatic protection switching (APS) channel in the Synchronous Optical Network (SONET) overhead for the tributary interfaces. Using the information contained in the APS channel, the EC1A controls switching of the tributary OC-3, Synchronous Transport Signal–Level 1 (STS-1), and optical virtual tributary group (OVTG) lines and units.

This unit is not required for DS1 and DS3 tributary interfaces because they do not contain DCC and APS overhead channels.




3.2 Features

Table 3-1 lists the EC1A unit(s) and associated supported features.

Table 3-1: EC1A Units and Associated Supported Features

Replaces the EC1A-DL1 unit.

√





The primary function of the EC1A unit is to access and process section, line and path overhead (SOH, LOH, and POH) in tributary DCCs associated with the Group 4 and 5 SONET interfaces. This includes all STS-1 (EC-1), OC-3, and OVTG tributaries. The EC1A unit also controls switching of the middle-speed tributary lines and units.

The EC1A-V2 unit supports the synchronization messaging application in ROM-based units. It does not support LAN/cell relay FASTLANE applications.

The EC1A-DL1 unit is used for SWDL systems.

The EC1A-DL2 unit is used for all SWDL applications. It is the interface between the MP1A-ADL/MP1A-V3 unit (FLM 150 ADM) and FASTLANE applications through the MC1A-APU or MC1A-APU2 unit.

Figures 3-1 and 3-2 show the functional block diagrams for the EC1A/-V2 and EC1A-DL1/-DL2 units respectively.

3.4 Options

Hardware Options

These units have no option switch settings.


The EC1A-DL1/-DL2 unit does not usually have to be provisioned when being replaced, even though provisioning parameters exist that affect unit operation. The MP1A and SV1A units maintain all option settings that are applied to the currently installed EC1A unit.

When the EC1A-DL2 unit is used in ROM-based applications, the on-board ROMs do not have to be replaced for future firmware upgrades. The on-board FLASH memory receives its new “firmware” through an automatic download from the SV1A-TL4 unit. When used in SWDL applications, the EC1A-DL2 unit receives its new software through the standard SWDL process.

All software provisioning options are written to, and maintained in the MP1A and SV1A units. Provisioning is performed using a craft interface terminal or operations support system (OSS) interface and is available for selections such as alarm indication signal (AIS) format, bit error rate (BER) threshold, service status, and the ability to monitor/inhibit incoming signal alarms. Refer to the Turn-Up and Operation practice (FJTU-320-515-270), Section A, Software Provisioning.




3.5 Front Panel Description

The front panel of the EC1A unit has two LEDs. These are shown in Figure 3-3 and listed in Table 3-2.

Table 3-2: EC1A Unit LED Descriptions

3.6 Compatibility

The EC1A unit is compatible only with basic ROM-based platforms.

The EC1A-V2 unit (supporting synchronization messaging) is used in ROM-based systems and is compatible only with Release 11 firmware for the FLM 150 ADM. If it is used with Release 10 for the FLM 150 ADM, erroneous alarms may be generated, even though service outages will not occur.

The EC1A-DL1 unit (SWDL) is compatible only with the MP1A-ADL and SV1A-TDL1 units. It can be used with SWDL Release 11.1S for the FLM 150 ADM; however, FASTLANE applications will not be supported in systems configured with EC1A-DL1 units. If the EC1A-DL1 unit is used in Release 11 ROM-based systems, a unit mismatch will be generated. This alarm will be indicated by a flashing FAIL LED and an autonomous alarm message.

The EC1A-DL2 unit for SWDL applications, is compatible only with Release 11 firmware for the FLM 150 ADM It may be used in some later versions of ROM based systems. It is fully backward compatible with existing hardware and can replace the EC1A-DL1 unit.

For more details on compatibility, see the Application Engineering practice, FJTU-320-515-120.

3.7 Availability



In addition to providing front-panel LEDs, the EC1A units provide equipment failure and unit-removed alarm and status messages through the craft and OSS interfaces.

Unit Fiber Type Connector Type Part Number





The HC1A-3xxx unit receives three synchronous transport signal level 1 (STS-1) synchronous payload envelope (SPE) signals from the middle-speed channel units. These signals are then byte interleaved into an STS-3 SPE. The HC1A-3xxx unit then adds line and section overhead (LOH and SOH) channels to form the complete STS-3 signal

These units multiplex and demultiplex three STS-1 signals to and from an STS-3 signal timed by the reference timing from the timing, control, and access (TCA) unit. The section and line overhead bytes that are transferred to/from the HS1A unit are dropped and inserted in this unit. The STS-3 signal is then converted to an OC-3 by 1310-nm or 1550-nm laser diodes (LDs) for transport over the fiber. In the receive direction, optical/electrical (O/E) conversion is performed vice versa. For the optical parameters, refer to the Application Engineering practice, FJTU-320-515-120, Appendix B, Equipment Engineering.

Hardware Options

The HC1A-3xxx unit has no hardware option settings.


All software provisioning options are written to, and maintained in the MP1A and SV1A units. Provisioning is performed using a craft interface terminal or operation support system (OSS) interface and is available for selections such as alarm indication signal (AIS) format, bit error rate (BER) threshold, service status, and the ability to monitor/inhibit incoming signal alarms. Refer to the Turn-Up and Operation practice (FJTU-320-515-270), Section A, Software Provisioning.

4.6 Compatibility

The HC1A-31xA units that supports applications using MMF are fully backward compatible with all other Fujitsu OC-3 units at both the NE and the network level. However it is not recommended to use a MMF OC-3 unit at one end of a span and a different type of unit on the other end, since the MMF OC-3 units are designed for use with multi-mode fiber and other Fujitsu OC-3 units are designed for use with single-mode fiber (SMF).

For more information about compatibility, refer to the Application Engineering practice, FJTU-320-515-120.

• Bit error rate (BER) monitoring

• Section/line overhead access

• Adds and drops section and line overhead

• Time slot assingment (TSA) function

• Byte interleaving mux/demux

• Pointer processing

• O/E, E/O converter

The HC1A-6Lx1 unit multiplexes and demultiplexes up to three STS-1 synchronous payload envelopes (SPEs) to and from an OC-12 signal. The HC1A unit works with the MP1A and HS1A units to process performance data and perform TSA functions for the OC-12. The HC1A-6Lx1 units provide add/drop functionality for a maximum of three STS-1 signals per FLM 150 ADM. Any additional STS-1 signals contained in the OC-12 signal pass through to the opposite HC1A-6Lx1. The HC1A also communicates with the timing, control, and access (TCA) unit for synchronization.

Transmit Direction

In the transmit direction (OPT OUT), the HC1A-6Lx1 unit receives up to three STS-1 SPE signals from the MC1A middle-speed channel units. The rest of the 12 signals (pass through signals) are received from the other HC1A high-speed channel unit. These signals are byte interleaved into an STS-12. Line overhead (LOH) and section overhead (SOH) are added to the first STS-1 channel to complete the STS-12 signal. After the necessary overhead information has been added, the signal is scrambled and converted to an optical signal.

Receive Direction

In the receive direction (OPT IN), the HC1A-6Lx1 unit receives the OC-12 signal, converts it into an electrical signal, and descrambles it. After the data contained in the LOH and SOH is processed, the resulting signal is demultiplexed into 12 separate SPE signals. Up to three of these may be dropped to the MC1A unit(s) while the rest are sent to the other HC1A unit for continuation around the ring.

All pass-through STS-1s are handled through a pair of ribbon cables that connect the two HC1A-6Lx1 units.

6: High-Speed Channel (HC1A-STS1) Unit

6 High-Speed Channel (HC1A-STS1) Unit

This section describes the functions of the FLM 150 ADM high-speed channel-STS1 (HC1A-STS1) unit. The unit provides the tributary interface and input/output processing for up to three STS-1 signals. It processes STS-1 signals and sends the STS-1 synchronous payload envelopes (SPEs) to the appropriate TS1A or MC1A unit for further processing. In the reverse direction, the HC1A-STS1 unit converts STS-1 SPE information back to the STS-1 format.

6.1 Features

The features supported by the HC1A-STS1 unit are as follows:

• Loss of signal (LOS), loss of frame (LOF), and loss of pointer (LOP) monitoring

• Path overhead (POH) monitoring in ring configurations

• Path protection switching in ring configurations

• Alarm indication signal (AIS) generation and line and path AIS detection circuitry

• Line build out (LBO) selections.


The HC1A-STS1 provides input/output (I/O) processing for up to three STS-1 channels. This processing includes decoding, descrambling, and drop handling in the receive direction, and coding, scrambling, and signal conditioning in the transmit direction.

Transmit Direction

In the transmit operation, up to three STS-1 (51.84 Mb/s) signals are prepared for transmission. In this process, each signal is processed in the following manner:

• Scrambled to improve quality through noise reduction

• Coded with line and section overhead information

• Converted to bipolar format

• Conditioned by LBO to match the appropriate cable length.

In addition, section and line overhead information is inserted.




Receive Direction

During receive processing, each STS-1 (51.84 Mb/s) signal is processed as follows:

• Converted to unipolar format

• Decoded to determine signal parameters

• Checked for proper parity

• Descrambled

• Stripped of section and line overhead information

• Checked for loss of frame (LOF), loss of signal (LOS), line alarm indication signal (LAIS), remote failure indication (RFI), and bipolar violation (BPV).

The payload is then sent to the TS1A or MC1A unit.

7: High-Speed Switch (HS1A) Unit

7 High-Speed Switch (HS1A) Unit

7.1 General

This section describes the functions of the high-speed switch (HS1A-AD1/-AD2) unit as it is used in the FLM 150 ADM systems. The unit controls the high-speed line and unit protection switching for all configurations of the FLM 150 AD. Only one HS1A unit is used in each shelf.

7.2 Features

Table 7-1 lists the HS1A unit(s) and associated supported features.

Table 7-1: HS1A Units and Associated Supported Features

Feature HS1A-AD1 HS1A-AD2

Supports both 150 terminal and ADM (including ring) configurations. √ √

√ √

√

The HS1A unit accesses and processes the path, line, and section overhead bytes on the high-speed line in the SONET Synchronous Transport Signal Level 1 (STS-1) format. The HS1A unit overhead processing complies with all SONET standards.

The HS1A unit provides automatic protection switching (APS), line alarm indication signal (LAIS), and remote failure indication (RFI) for all the STS-1 channels in the STS-3 signal. Both bidirectional and unidirectional (1:1 ratio) switching can be performed. For bidirectional switching, if a failure occurs on the receiving line of the local shelf, the receiving and sending lines will be switched to the Protect lines. For a unidirectional switch, the signal going in one direction only is switched. This choice is user provisionable through the craft or operation support system (OSS) interface.

The HS1A unit also provides an SDCC interface for transporting end-to-end Operation Support information.

The HS1A unit controls protection switching for the high-speed line based on information obtained by monitoring the path, line, and section overhead bytes. In addition, the unit processes and modifies the SONET overhead bytes for the STS-3. For additional information, refer to the Guide to SONET practice, FJTU-320-500-500.




Transmit Direction

In the transmit direction, the HS1A unit provides a data link with other network elements (NEs) by supplying information for the path, line, and section overhead channels for the STS-3 signal. This information is sent to the high-speed channel (HC1A) units where it is placed in the appropriate overhead bytes and added to the synchronous payload envelope (SPE) to form the STS-3. These overhead bytes are used for signaling to various types of NEs and to provide performance monitoring (PM) functions.

The HS1A unit provides section and line overhead for the STS-3 signal. Section overhead information is processed by each lightwave NE to accomplish basic transport functions over each section of the signal path. It includes signal framing and identification information, section performance monitoring information, and a 192-kb/s SDCC. Line overhead is processed by all line-terminating NEs to facilitate payload management. The overhead includes automatic protection switching commands and a 576-kb/s DCC for future use.

When an automatic protection switch (APS) has been activated in the receive direction, the HS1A signals that a switch has occurred in the APS channel of the return signal.

The HS1A unit, in conjunction with the MP1A unit, provides path overhead information for each of the three STS-1s in the OC-3 signal. Path overhead is used to provide end-to-end payload management at the service-terminating location of SONET networks. Path overhead information for STS-1 tributary signals is passed through the FLM 150 ADM without being modified. The HS1A unit accesses path overhead from the incoming STS-1 signal, divides it into its constituent tributaries, and sends it to the MP1A unit. Path overhead includes an STS path tracing function.

Receive Direction

In the receiving direction, the HS1A unit accesses and processes the path, line, and section overhead bytes from the received STS-3 signal. These data streams are received from the HC1A units and divided into individual overhead channels. These channels are either sent on to the MP1A unit for further processing or analyzed within the HS1A unit to obtain information on the quality of the incoming signal. Based on this information, the HS1A unit controls protection switching for the HC1A units.

Protection Switching

When degraded service is detected because of a failed optical line or a high-speed unit failure, the controller in the 8-bit CPU switches to the Protect unit. Both Working and Protect high-speed interfaces are transmitting and receiving at all times. This assures that the Protect line status is being monitored by the HS1A unit at all times. The HS1A unit controls protection switching from one circuit to the other based on bit error rate (BER) and unit status. The HS1A unit activates a switch to protect whenever the BER alarm threshold has been crossed. The BER alarm threshold is user provisionable through the craft/OSS interface.

The optical line is selectable as either a bidirectional or unidirectional switch. For bidirectional switching, if a failure occurs on the receiving line of a local shelf, the receiving and sending lines will be switched to the Protect lines. This is performed by transporting the switch request command to the remote shelf using the automatic protection switching (APS) byte in the SONET overhead. This command switches the receiving line at the remote shelf. For unidirectional switching, the signal going in one direction only is switched (Figure 7-2). This choice is user provisionable through the craft/OSS interface.

Nonrevertive Switching

A software option allows configuring the FLM 150 ADM for revertive or nonrevertive protection switching. When nonrevertive switching is selected for the high-speed interface a second “hit” will not occur when the failed circuit recovers.

Lock-In

The FLM 150 ADM provides lock-in functions to prevent successive switching of the unit and the line that can occur with intermittent digital errors. The lock-in is initiated when middle- or high-speed interface unit switching occurs four times in 10 minutes and remains for 24 hours or until lock-in is reset using the craft terminal. The lock-in function is software provisionable as either Allowed (Y) or Inhibited (N).

7.4 Options

Hardware Options

The HS1A unit switch options are used to set up the direction of the data link around a ring. The data link consists of far-end alarms via the Far End Select (FE SEL) button on the Microprocessor unit, orderwire, and telemetry byte-oriented serial protocol (TBOS). These switch options have no effect on DCC communication and are only valid when the NE is configured as a ring.

Even though these switch options only apply in ring applications, it is recommended that the same switch setting be used for terminal and linear applications. This consistency will make the upgrade easier if the need arises to change the configuration of a point-to-point or linear system to a ring.

These options are defined in the following paragraphs. Figure 7-3 shows the HS1A unit front panel and the hardware option settings and locations.




TBOS 1/2

This switch is used to set the normal direction of the data link in a ring application. All nodes in a given ring should be set to the same direction. The factory default setting is “1” TBOS.

F1 Set

This switch sets the content of the F1 byte in the SONET overhead. This byte is used by the FLM 150 ADM in ring applications for signaling. When this switch is set in the Open (OFF) position, the FLM 150 ADM ring node will transmit all 1s in the F1 byte if it detects a failure. This signal will be relayed by all SLAVE nodes in the ring. In addition, each node will switch its data link direction upon receiving the signal. When this switch is set in the Closed (ON) position, the node detecting a failure transmits all 0s in the F1 byte. All 0s signaling is not relayed by subsequent nodes. The factory default setting is Open (OFF).

RESTR (Restore)

This switch is used in ring configurations to select whether restoration of the data link, in the event of an optical failure, is desired. If restoration is desired, set this switch to the Closed (ON) position. If data link restoration is not required, set this switch to Open (OFF). The factory default setting is the Closed (ON) setting.

This switch is used to select whether a given FLM 150 ADM node is being optioned as the data link Master. Only one node in a ring or network can be optioned as the MASTER. All other nodes must have this switch set in the SLAVE position.


All software provisioning options are written to, and maintained in the MP1A and SV1A units. Provisioning is performed using a craft interface terminal or OSS interface and is available for selections such as alarm indication signal (AIS) format, BER threshold, service status, and the ability to monitor/inhibit incoming signal alarms. Refer to the Turn-Up and Operation practice (FJTU-320-515-270), Section A, Software Provisioning.

8 Low-Speed Channel (LC1A-D1/D1E/D1E2) Unit

8.1 General

This section describes the LC1A DS1 interface units used in the FLM 150 ADM system. Each unit provides SONET multiplexing/demultiplexing for up to four DS1s on the low-speed side and one SONET virtual tributary group (VTG) on the high-speed side.

8.2 Features

Table 8-1 lists the LC1A unit(s) and associated supported features.

Table 8-1: LC1A Units and Associated Supported Features

Synchronous Optical Network (SONET) compatibility with floating VT 1.5 asynchronous mapping for DS1.

√ √ √

Adjustable bit error rate (BER) threshold for path switching: 10–5, 10-6, 10–7, or 10–8.

√ √ √

All 1s or all 0s for DS1 alarm indication signal (AIS). √ √ √

DS1 line code: B8ZS or alternate mark inversion (AMI). √ √ √

DS1 loopback: Near-end facility loopback and far-end terminal loopback.

Bipolar violation (BPV), bit interleaved parity-2 (BIP-2) detection circuit.

√ √ √

Performs virtual tributary (VT) path selection (ring) on receipt of VT unequipped code.

In ring configurations only, receipt of the VT unequipped code from one direction automatically triggers a path switch to the VT signal coming from the other direction.

√ √




Injects VT alarm indication signal (AIS) on the receipt of DS1 oss of signal (LOS) or AIS.

Detection of any incoming DS1 failure causes injection of VT AIS for the duration of the failure. This feature is useful when interconnecting rings at the DS1 rate. By enabling this option, any DS1 level failure (for example, a DS1 cable problem) has visibility within the SONET envelope, thus allowing path switching to occur. Previously, the DS1 spans between the back-to-back terminals could have caused signal failure because a failure at the DS1 level was transparent to the path-switching functions of the ADM.

√ √

Provides path performance monitoring (PM) based on frame errors (SFs) or CRC-6 errors (ESFs).

√ √

Automatic protection switching (APS) on signal label mismatch (SLM).

In addition to unequipped code path switching, this feature enables path switching on receipt of any payload other than VT mapped.

√

Software provisionable LBO settings.

This allows independent LBO settings for each DS1 channel. The Protect slot LC1A-D1E2 automatically accepts the LBO settings of the failed LC1A-D1/-D1E/D1E2 unit when protection switching is initiated. The default setting remains 0 to 250 feet.

Transmit Direction

In the transmit direction, each incoming DS1 signal (up to four) from the DSX-1 is converted from bipolar (AMI or B8ZS) to a unipolar format and mapped into two identical VT1.5 signals. These VT1.5 signals, along with the signals from the other three channels, are fed to a pair of multiplexers. There they are multiplexed into two identical 6.912-Mb/s VTG signals that constitute the output of the unit.

Loss of an incoming DS1 or detection of a DS1 AIS causes an alarm condition report only if the incoming signal alarm inhibit (SINH) is disabled. In this case, VT AIS is inserted automatically by the LC1A unit. If a loss of the 6.912 Mb/s output signal is detected, an associated alarm is generated, and VTG AIS is substituted for the transmit direction signal.

Receive Direction

In the receive direction, the incoming Working and Protect VTG signals are individually demultiplexed into four VT1.5 channels. Working or Protect is selected independently for each of the VT1.5 channels. The VT unipolar signals are then converted to bipolar 1.544-Mb/s DS1 signals. Each DS1 signal then passes through the LBO circuitry located at the unit’s low-speed output.

If a loss of the incoming VTG signal is detected, an associated alarm or status information report is generated, and DS1 AIS is substituted in the outgoing DS1 channels. If an incoming VT AIS is detected, DS1 AIS (all 1s or 0s alternate) is generated and the status information is reported.

All status/alarm information is sent to the Microprocessor (MP1A) Unit for processing.

Blinking red Unit MISMOUNT: the system is configured for a different mode or the mounted unit is not used in this configuration.



LINE Red The incoming signal has degraded or failed. A service-affecting alarm such as a BPV within a DS1, or an LOS, loss of frame (LOF), or BER exists.

Yellow One or more non–service-affecting path-level conditions exist. Possible conditions include an AIS within the VT path or an unequipped code (UNEQ).





8.6 Compatibility

The following guidelines apply for combining LC1A units:

• The LC1A-D1E units cannot be mixed with the LC1A-D1 units in the same group.

• The LC1A-D1E2 units can be mixed with either the LC1A-D1 or the LC1A-D1E units. The LC1A-D1E2 will function as either an LC1A-D1 or LC1A-D1E, depending on the low-speed group provisioning. Do not mix the LC1A-D1E2 unit with both LC1A-D1 and LC1A-D1E units in the same group.

None of the features of these units require that a specific type of DS1 interface unit be installed at the far end of the DS1 channel.

The following describes MP1A and SV1A compatibility with LC1A units for the FLM 150 ADM:

• All LC1A-D1 and LC1A-D1E features are supported by all MP1A and SV1A types.

• LC1A-D1E2 features are supported by MP1A-V3 and SV1A-TL4 units as well as the software download units (MP1A-ADL and SV1A-TDL1).

• LC1A-D1E2 units installed in a shelf with MP1A-V2 and SV1A-TL2 will perform only the LC1AD1E level of performance monitoring (PM). The LBOs will automatically be set to 0 to 250 feet and are not provisionable.


8.7 Availability



In addition to the front-panel LEDs, the MP1A unit provides equipment failure and unit-removed alarm and status messages through the craft and OSS interfaces.



9: Low-Speed Channel OVTG Optical (LC1A-F6)Unit

9 Low-Speed Channel OVTG Optical (LC1A-F6) Unit

9.1 General

The LC1A-F6 is a low speed channel—optical virtual tributary group (OVTG) unit that is used in the FLM 150 ADM system. The basic function of this unit is to provide an OVTG interface to the FLM 6. Table 9-1 lists the different types of LC1A units. All four of these units are functionally identical; the only difference is the optical connector type.

9.2 Features

The features supported by the LC1A-F6 units are as follows:

• Optically extends four VT1.5 signals out to an FLM 6, thus extending the SONET envelope out to the customer premises

• Provides an extended-temperature 6.912-Mb/s OVTG interface

• Multiplexes and demultiplexes four DS1 signals to/from VTG signals

• Uses the SONET VT structured multiplexing method

• Provides nonrevertive path protection switching (as does the LC1A-D1 unit)

• Provides 1+1 optical line switching toward the FLM 6

Table 9-1: LC1A Unit Characteristics

Unit Connector Part Number

LC1A-F6 FC FC9612LF61

LC1A-F6C1 SC FC9612LC61

LC1A-F6T1 ST FC9612LT61

LC1A-F6D1 D4 FC9612L461





The LC1A-F6 unit optically extends four VT1.5 signals out to the FLM 6. The FLM 6 terminates the VT path and provides four DS1 interfaces. The optical signal is identified as an optical virtual tributary group (OVTG).

The LC1A-F6 unit can be installed in either low-speed Groups 4 or 5, but not Group 3, of the FLM 150 ADM shelf. Within each low-speed group, the LC1A-F6 unit can be configured as either seven unprotected or four protected (1:1) OVTG interfaces. Shelf capacity in the FLM 150 ADM is therefore either 14 unprotected or 8 protected OVTGs.

Note: All units installed in a low-speed group must of the same type (for example, LC1A-D1Es cannot be mixed with LC1A-D1 or LC1A-F6 units in the same group).

Note: The LS1A-D1 unit is required for the Protected LC1A-F6 configuration.

Transmit Direction

In the transmit direction, four VT1.5 signals from the MC1A-MDM1 FLM 150 ADM are multiplexed into an OVTG signal and sent to the FLM 6. For the optical parameters, refer to the Application Engineering practice, FJTU-320-515-120.

Receive Direction

In the receive direction, incoming OVTG signals from the FLM 6 are converted to electrical signals without terminating the VT1.5 path overhead bytes. The resulting four VT1.5 signals are then sent to the MC1A-MDM1 unit in the FLM 150 ADM.

10: Low-Speed Switch (LS1A-D1) Unit

10 Low-Speed Switch (LS1A-D1) Unit

10.1 General

This section describes the functions of the Low-Speed Switch 1 (LS1A-D1) unit used in the FLM 150 ADM systems. The LS1A-D1 unit controls the low-speed line and the unit protection switching. The primary function of the LS1A-D1 unit is to provide automatic protection switching for the low-speed channel (LC1A) unit.

10.2 Features

The features supported by the LS1A-D1 unit are as follows:

• 1:7 protection switching for LC1A-D1/-D1E/-D1E2 units

• 1+1 protection switching for the LC1A-F6 unit

• Data communication channel (DCC) connectivity for the protected LC1A-F6 (4WP) configuration

• Support for terminal, linear add/drop multiplexer (ADM), and ring configurations





When the low-speed LC1A-D1/-D1E/-D1E2 channel unit is used, the incoming DS1 signals are protected 1:7. When a low-speed unit fails or is removed, the LS1A unit selects the affected backplane signals and reroutes them to the Protect LC1A-D1/-D1E/-D1E2 unit. Traffic flows through the LS1A unit only when a switch is in progress; therefore, if normal traffic flow is in progress, the LS1A unit can be removed from the backplane without loss of service.

The incoming low-speed signal is switched before the signal has reached the interface circuit. This architecture requires that all eight low-speed interfaces in the 1:N switch subsection must be of the same type (for example, if LC1A-D1 units are being used in low-speed Group 5 in the FLM 150 ADM, all units in Group 5 must be LC1A-D1s).

Because the FLM 150 ADM provides revertive switching for the low-speed interface switch, when the failed low-speed interface unit is replaced, the switch back from the Protect unit occurs automatically.

The LS1A-D1 provides switching control for up to eight LC1A low-speed interface units. Of the eight low-speed units, seven are working, and one is equipped for protection.

Note: The LS1A-D1 unit must also be used with the LC1A -F6 low-speed channel–optical virtual tributary group (OVTG) unit in the protected configuration. In addition to providing automatic protection switching, the LS1A-D1 unit is required for data communications channel (DCC) connectivity in this configuration.

11 Middle-Speed Channel (MC1A-D3/D3A2) Unit

11.1 General

This section describes the functions of the FLM 150 ADM Middle-Speed Channel-DS3 units (MC1A-D3 and MC1A-D3A2). These units provide the interface and input/output processing for DS3 rate signals. They map the DS3 payload into an STS-1 synchronous payload envelope and transmit it to the high-speed units for further processing and interleaving. In the reverse direction, the units convert STS-1 payload envelope information into the DS3 format.

11.2 Features

Table 11-1 lists the MC1A-D3 and MC1A-D3A2 unit(s) and associated supported features.

The following paragraphs describes the operation of the MC1A-D3 and MC1A-D3A2 units.

Transmit Direction

In the transmit direction, incoming DS3 (44.736 Mb/s) signals (to the S-IN connector) are converted from bipolar to unipolar (B/U) format and mapped into the SONET STS-1 payload envelope format. These DS3 signals are decoded and monitored for signal degradation in a synchronization send (SYNC S) circuit. The signals are multiplexed and divided into data streams for further processing.

Note: The designations S-IN and R-OUT are the way the connectors are labeled on the back of the FLM 150 ADM shelf.

Receive Direction

In the receive direction, data signals are demultiplexed and mapped into DS3 signals. These unipolar signals are converted to bipolar DS3 signals and transmitted. They are monitored for signal degradation in the synchronization receive (SYNC R) circuit, coded into a bipolar format, and routed to the DS3 R-OUT connector. An line buildout (LBO) circuit on the receiving side provides an equivalent cable distance of 450 feet. Front-panel LEDs provide alarm indications. The units provide automatic switching functions to execute the protection line.

Loopback Capabilities

The MC1A-D3/-D3A2 units also provide terminal loopback (TLB) and Facility Loopback (FLB) capabilities. TLB returns the signal received from the HC1A unit back through the HC1A unit after the signal has been processed by the MC1A-D3/-D3A2 circuits. FLB returns the incoming DS3 signal to the sending device before the signal has been sent to the High-Speed Channel Unit (HC1A). Loopback switching can be initiated from either the local or remote terminal through the craft interface.




STS-1 Path Switching

The MC1A-D3A2 unit can optionally perform STS-1 path switching based on the detection of STS-1 unequipped code. This option is applicable to unidirectional path switched (UPS) rings only. The FLM 150 ADM can automatically insert STS-1 unequipped code (within the OC-n or EC-1). If no cross-connect exists for a particular STS-1, the MC1A-D3A2 performs path switching upon detection of the STS-1 unequipped code. This option prevents the loss of service due to accidental deletion of system cross-connects.

Injection of STS-1 AIS

The MC1A-D3A2 unit can optionally inject STS-1 alarm indication signal (AIS) whenever incoming DS3 AIS or loss of signal (LOS) is detected. This feature is used to interconnect between rings at the DS3 rate. With this option enabled, any DS3 level failure will have visibility within the SONET envelope and allow path switching. Previously, the DS3 spans between the back-to-back terminals could have caused signal failure because a DS3 level failure was transparent to the path switching function of the ADM. The MC1A-D3A2 provides a solution for this application.

12: Middle-Speed Mux/Demux (MC1A-MDM1)Unit

12 Middle-Speed Mux/Demux (MC1A-MDM1) Unit

12.1 General

This section describes the functions of the FLM 150 ADM middle-speedmux/demux (MC1A-MDM1) unit. The unit is the STS-1 signal interface to/from the LC1A-D1 low-speed unit. Each unit multiplexes and demultiplexes seven virtual terminal (VT) group signals to and from the STS-1 SPE (synchronous payload envelope) signal. These VT group signals are converted into synchronous transport signal level 1 (STS-1), where they are multiplexed and routed to a high-speed channel (HC1A) unit. The MC1A-MDM1 supports all FLM 150 ADM applications.

12.2 Features

The features supported by the MC1A-MDM1 unit are as follows:

• Multiplexes seven virtual tributary (VT) groups into an STS SPE (synchronous payload envelope)

• Demultiplexes an STS SPE into seven VT groups

• Adds and drops STS-1 path overhead





The primary function of the MC1A-MDM1 unit is to multiplex and demultiplex VT group signals into SONET STS-1 payload capacity to send on to the HC1A unit and vice versa.

Transmit Direction

In the transmit direction, incoming VT group signals received from the LC1A are byte-interleave multiplexed based on the timing received from the timing, control, and access unit (TCA) unit, and STS-1 path overhead bytes are added. The MC1A-MDM1 can accept up to seven VT group signals. The signals are then multiplexed and divided into data streams suitable for processing in the HC1A unit.

Receive Direction

In the receive direction, data signals are received, demultiplexed, and divided into seven VT group signals. When alarms are generated, LEDs will give a visual indication on the front panel of the MC1A-MDM1 unit. When alarms are generated, the CPU in the MP1A unit provides automatic switching signals to operate the protection line switch.

13: Middle-Speed Channel (MC1A-STS1/-ST1P)Unit

13 Middle-Speed Channel (MC1A-STS1/-ST1P) Unit

13.1 General

This section describes the functions of the FLM 150 ADM Middle-Speed Channel-STS1/ST1P Interface Unit (MC1A-STS1/-ST1P). The MC1A-STS1/-ST1P units provide the tributary interface and input/output processing for up to three STS-1 signals. The MC1A-STS1/-ST1P units process the STS-1 signal and send the STS-1 synchronous payload envelope (SPE) to the high-speed channel units for insertion into the OC-3. In the reverse direction, the MC1A-STS1/-ST1P units convert STS-1 SPE back to the STS-1 format.

13.2 Features

Table 13-1 lists the MC1A-STS1/-ST1P unit(s) and associated supported features.

The primary function of the MC1A-STS1/ST1P unit is to convert STS-1 signals into the format required by the HC1A units and vice versa. The unit also monitors each STS-1 for signal quality and uses this information and information contained in the path, line, and section overhead to control protection switching.

Transmit Direction

In the transmit direction, each incoming STS-1 IN (51.840 Mb/s) signal is converted from a bipolar to unipolar (B/U) format, decoded, and descrambled. The section and line overhead is dropped, and performance data is transferred to the R OUT overhead insertion circuits of the HC1A unit. Path overhead information is monitored and H-byte (pointer) information is inserted. The signals are then converted into data streams suitable for processing in the HC1A unit.

Receive Direction

In the receive direction, data signals are received from the HC1A unit. These data streams are converted to a serial format, and path overhead information contained in them is monitored. Payload pointer information and line and section overhead are inserted. The signal is then scrambled and converted to a unipolar serial format. This unipolar signal is converted to a bipolar STS-1 and transmitted. When an MC1A unit failure, LOS condition, or LOF condition is detected, the MC1A-STS1/ST1P units provide automatic switching functions. An LBO circuit on the R OUT side provides an equivalent cable distance of 450 feet.


The MC1A-STS1/ST1P also provides TERM loopback and FAC loopback capabilities. Loopback testing is effective in isolating signal failures.

Facility loopback returns the incoming STS-1 signal to the sending device before it has been sent to the High-Speed Channel (HC1A) Unit. Terminal loopback returns the signal received from the HC1A unit back through the HC1A unit after it has been processed by the MC1A-STS1-/ST1P circuits.

Initiate loopback switching though the craft interface from either the local or remote terminal.

14: Middle-Speed Transmux (MC1A-TMxx) Unit

14 Middle-Speed Transmux (MC1A-TMxx) Unit

14.1 General

This section describes the functions of the FLM 150 ADM middle-speed channel transmux units with EC1 interface (MC1A-TME1) and DS3 interface (MC1A-TMD3).

FLM 150 ADM In the MC1A-TME1 unit, STS-1 signals are demapped to DS3 signals. The DS3 signals are demultiplexed into DS1 signals, then mapped to VT1.5 rate signals. The VT1.5 signals are mapped to the STS-1 synchronous payload envelope before transmitting to the high speed units for further processing and interleaving.

The MCIA-TMD3 unit demultiplexes the DS3 payload into DS1 rate signals. The DS1 signals are mapped to the VT1.5 rate signals, then mapped to the STS-1 synchronous payload envelope. From there the STS-1 signals are further processed and interleaved.

In the reverse direction MC1A-TMxx provides STS-1 path switching function for combination with current TS1A, TS1A-ENH, and TS1A-ENH2 units.

14.2 Features

• VT1 performance monitoring

• Support M13 format and C-bit parity format for DS3 signal frame format

• Software provisionable line build out (LBO) Selections

• Terminal and facility loopback functions

• In–band loopback functions for DS3 C-bit parity format

• Out–of–band loopback functions for DS3/EC-1/DS1

• Performs VT1.5 path selection and grooming into physical EC-1, OC-3, optical virtual tributary group (OVTG), and DS1 interfaces

15: Middle-Speed Channel OC-3 Optical (MC6A-3xxx/-31xx) Unit

15 Middle-Speed Channel OC-3 Optical(MC6A-3xxx/-31xx) Unit

15.1 General

This section describes the functions of the Middle-Speed Channel OC-3 (MC6A-3xxx/-31xx) medium-range, short-range, and long range units as they are used in the FLM 150 ADM. These units provide the interface and input/output processing for one OC-3 rate signal.

Unless specified otherwise, all the Middle-Speed Channel OC-3 units are referred to generically as MC6A-3xxx throughout this section.

The MC6A-3xxx unit demultiplexes the OC-3 payload into one STS-1 synchronous payload envelope (SPE) and transmits it to the high-speed units for further processing and interleaving. In the reverse direction, the MC6A-3xxx unit converts STS-1 SPE information received from the high-speed channel units to the OC-3 format. These units can be used in the FLM 150 ADM, FLM 2400 ADM High Density TRIB shelf, and FLM 600 ADM stand alone and TRIB shelf. Although these units can be used in all three products, the signal flow and provisioning options vary depending upon the product. This section describes the signal flow and hardware options of the units as used in the FLM 150 ADM. These units can be installed in the middle-speed Groups 4 or 5 of the FLM 150 ADM shelf.

Transmit Direction

The incoming OC-3 (155.520 Mb/s) signal is converted from serial to parallel and descrambled into SONET STS-3 format. The section overhead (SOH) is dropped, and the signal is demultiplexed into its constituent STS-1 signals. The line overhead (LOH) is dropped from each STS-1 and only the first STS-1 is sent to the high-speed units (HC1A) for further processing.

Receive Direction

An STS-1 SPE signal is received from the HC1A units. LOH and SOH are added and the three data streams are byte interleaved. After parallel-to-serial conversion, the resulting STS-3 is scrambled and sent out as an OC-3.


FAC and TERM Loopback capabilities are also provided. A facility loopback returns the incoming OC-3 signal to the OC-3 output before the parallel to serial conversion (see the LB block on the right side of the diagram). This allows testing the tributary OC-3 source, optical cross-connect, optical cables, and MC6A unit input/out circuits.

A terminal loopback returns the signal received from the HC1A unit back through the HC1A unit after it has been processed by most of the MC6A-3xxx circuits. This sends it back to the far-end, or originating site, where the loop testing is being done.

Loopback control may be initiated from either the local or remote terminal through the craft interface options.




Figure 15-1 shows the functional block diagram of the MC6A-3xxx plug-in units. The primary function of the MC6A-3xxx unit is to convert OC-3 signals to and from the STS-1 payload envelope (SPE) format.

The terms transmit and receive relate to the shelf ’s high-speed (OC-3)interface . Added signals travel in the transmit direction and dropped signals in the receive direction.

15.4 Options

Hardware Options

The following paragraphs describe the SONET/SDH hardware option switch that is available on the MC6A-31xL/-31xM/-31xS and MC6A-31xA units. Even though the SDH setting is shown and described in the following paragraphs, the SDH setting is not used in the FLM 150 ADM system.

With MC6A-31xL/-31xM (Issue 2), MC6A-31xS (Issue 2 and later), and MC6A-31xA units, the SONET/SDH option, both Segment 1 and Segment 2 of the DIP switch should be set to OPEN for SONET applications or CLOSED for SDH applications.

When both switches are set to OPEN for SONET (factory default), the transmit SS bits pattern on bits 5 and 6 of each H1 byte = 00 (STS1#1), 00 (STS1#2), and 00 (STS1#3).

When both switches are set to CLOSED for SDH, the transmit SS bits pattern on bits 5 and 6 of each H1 byte = 10 (STS1#1), 11 (STS1#2), and 11 (STS1#3).

Figure 15-4 shows a view of the hardware option switch locations and default settings on the MC6A-31xL/-31xM (Issue 2), MC6A-31xS (Issue 2 or later), and MC6A-31xA units. Except for the part number, it is the same for all units.

With MC6A-31xL/-31xM (Issue 3) units, only Segment 1 of the DIP is used to set the SONET/SDH option. Segment 1 should be set to OPEN for SONET or CLOSED for SDH applications. Segment 2 is reserved for manufacturing purposes and should not be changed from the default setting.

Figure 15-5 shows a view of the hardware option switch locations and default settings on the MC6A-31xL (Issue 3) unit.

15.6 Compatibility

The MC6A-31xA units that support MMF applications and the MC6A-31xS (Issue 3 or later) units that support SMF or MMF applications are fully backward compatible with all other Fujitsu OC-3 units at both the NE and the network level. It is important to understand that the MC6A-31xA units support only MMF and are designed to different specifications than those of the MC6A-31xS units and therefore are not fully compatible with each other. The primary differences between these two specifications are the optical transmit and receive power levels.

Table 16-1: MC6A Units and Associated Supported Features (cont’d)

Feature MP1A MP1A-V2 MP1A-V3 MP1A-R11 MP1A-ADL





The MP1A-V2/-V3/-R11unit functions as the main controller that processes alarm and status information in all FLM 150 ADM configurations. The unit consists of two 16-bit CPU buffers, electronically erasable programmable read-only memory (EEPROM), random access memory (RAM), and peripheral input/output (I/O) circuits to other units. The CPU monitors and controls provisioning data in the shelf according to the program stored in ROM. The RAM functions as a work area, while the EEPROM registers alarm and status data.

In the MP1A-ADL unit, the download program is stored in FLASH memory. The CPU monitors and controls provisioning data in the shelf according to the download program. All provisioning data is maintained in non-volatile FLASH memory, enabling the system to recover power loss without human intervention. The MP1A stores the standby database file for the database restoral process.

The MP1A unit also communicates with the SV1A unit.

16.4 Options

Hardware Options

The MP1A unit is equipped with a 10-position rotary switch that sets the equipment ID number of the network element (NE). As many as nine shelves in the network can be assigned a unique number. With a jeweler’s screwdriver, turn the switch until the white arrow points to the desired number.

ID numbers should not be duplicated within a system. If more than nine NEs exist in a system, the remaining NEs must be set to zero. Assigning unique shelf equipment ID numbers allows the MP1A unit to work with the AW1A unit to monitor far-end alarm/status LEDs.

16.6 Compatibility

The compatibility for the MP1A units is listed below:

• The MP1A unit is compatible only with the SV1A-TL1 and EC1A units. These units are now “manufacturing discontinued.”

• The MP1A-V2 unit is compatible with the SV1A-TL2 and -TL3 units and the EC1A/EC1A-V2 unit. The SV1A-TL2 and -TL3 units are now manufacturing discontinued.

• The MP1A-V3 unit can only be used in conjunction with the SV1A-TL4 unit, and only of the same release level. Fujitsu does not recommend using newer issues of the MP1A-V3 unit with older issues of the SV1A-TL4 unit, because it may be traffic affecting. The EC1A/EC1A-V2 can be used with the MP1A-V3 unit.

• The MP1A-R11 can only be used with SV1A-R11 units. Either the EC1A/EC1A-V2 or EC1A-DL2 unit can be used with the MP1A-R11.

• The MP1A-ADL unit is compatible only with the SV1A-TDL1 and EC1A-DL2 units (with Release 11 or above)


CAUTION:Traffic may be affected if Release 9.1 or 10 units are mixed with Release 11 units using synchronization status messaging or if the NE uses Release 11 for the FASTLANE feature (ethernet port mapped bridge or DS3 UNI cell relay).

16.7 Availability



In addition to providing front panel LEDs, the MP1A unit provides equipment failure and unit-removed alarm and status messages through the craft and OSS interfaces.



17: Power (PW1A) Unit

17 Power (PW1A) Unit

17.1 General

This section describes the functions of the FLM 150 ADM Power (PW1A) Unit. This unit generates secondary voltages for use by the FLM 150 ADM shelf from the –48 V dc office supply.

17.2 Features

The PW1A unit provides the following main features:

• Input overload protection

• Front panel alarm and status LEDs

• Test jacks for voltage measurements.


The unit converts the primary –48 V dc battery supply to +5.4 and –5.6 V dc sources through dc to dc converters. The PW1A unit generates secondary voltages that are supplied to each plug-in unit installed into the FLM 150 ADM shelf. The secondary voltages can be measured through the test jacks provided on the unit front panel.

Although one PW1A unit will supply the FLM 150 ADM equipment, two units are normally installed to provide redundant power sources. If one unit fails, the other can power the entire shelf and maintain service. With one unit operating normally, the other unit can be removed and replaced without interrupting system power.

The –48 V dc primary power is applied to an input circuit containing test jacks and a circuit breaker. The circuit continues through the PW1A unit to be converted to +5.4 and –5.6 V dc. The circuit breaker installed in the –48 V dc input circuitry provides input overload protection to the FLM 150 ADM shelf.

At the output of each dc voltage source, a diode is wired so that a single power supply failure does not interrupt shelf power. A voltage detector circuit will initiate an alarm (LED) indication if an abnormal voltage output is detected.




Figure 17-1 shows a block diagram of the PW1A unit.

17.4 Options

Hardware Options

This unit has no option switch settings.


The PW1A unit requires no software provisioning. All software provisioning options are written to, and maintained in the MP1A and SV1A units. Provisioning is performed using a craft interface terminal or OSS interface and is available for selections such as AIS format, BER threshold, service status, and the ability to monitor/inhibit incoming signal alarms. Refer to the Turn-Up and Operation practice (FJTU-320-515-270), Section A, Software Provisioning.

SV1A-R11 SV1A-TDL1





The SV1A units provide the X.25 interface to transmit line condition and performance monitoring information to an OSS. They provide interface to the Microprocessor (MP1A) unit that provides memory administration and backup for overall control of the FLM 150 ADM system.

The SV1A-TDL1 unit provides memory backup for the MP1A-ADL unit. If the MP1A-ADL unit fails or is removed, the current system operating software is maintained in non-volatile FLASH memory. The provisioning database is retained in RAM and EEPROM on the MP1A-ADL, and in RAM in these units. When a replacement MP1A unit is inserted, the backup data is automatically written to the new unit. Conversely, inserting a new SV1A unit in a shelf that contains a working MP1A unit results in the automatic downloading of this data to the new SV1A unit.




Figure 18-1 shows the functional block diagrams for the SV1A-TL1/-TL2/-TL3 units.

The SV1A-TB unit provides the TBOS interface to send out line condition and performance monitoring information to a serial telemetry information gathering device supported by the local craft interface. This information is sent over the User Channel in the SONET overhead. The TBOS maps are provided in Tables 18-2 through 18-7.

Segment 1 of the Select OSS clock switch provides user selection of either OSS or back-to-back (B-B) connection of the FLM 150 ADM.

• Setting the switch to the OSS position connects the network management administration (NMA) to the local FLM 150 ADM.

• Setting the switch to the B-B position configures the FLM 150 ADM connection to another NE through the OSS1 connector on the backplane.

Segment 2 of the Select OSS clock switch is not used.

Note: If 10S (or later) software is in use, the selection between OSS and B-B is accomplished with a TL1 command.

All software provisioning options are written to, and maintained in the MP1A and SV1A units. Provisioning is performed using a craft interface terminal or OSS interface and is available for selections such as AIS format, BER threshold, service status, and the ability to monitor/inhibit incoming signal alarms. Refer to the Turn-Up and Operation practice (FJTU-320-515-270), Section A, Software Provisioning.


The front panels of the SV1A-TB, SV1A-TLx and SV1A-R11 units have three LEDs and a terminal connector (TERM). The terminal connector is a 25-pin, D-Sub connector, RS-232C interface that provides craft terminal or modem interface. The RS-232C interface, DCE operation, is used on the front panel of the SV1A units. The RS-232, DTE operation, is used through the modem connector (CN 11) on the backplane for modem access.

The front panel of the SV1A-TDL1 unit has an LED to indicate that software download is in progress.

The following describes the compatibility for each SV1A unit:

• SV1A-R11—compatible only with the MP1A-R11 unit.

• SV1A-TL4—compatible only with the MP1A-V3 unit. The SV1A-TL4 is backward compatible; however, Fujitsu does not recommend using newer issues of the SV1A-TL4 unit with older issues of the MP1A-V3 unit, because many features of the SV1A-TL4 will not be functional.

• SV1A-TDL1 unit—compatible only with the MP1A-ADL and EC1A-DL1/-DL2 units.

• SV1A-TB, -TL2, and -TL3—only compatible with the MP1A-V2 unit. These units are manufacturing discontinued.

• SV1A-TL1—only compatible with the MP1A unit. Both of these units are manufacturing discontinued.

For more details on compatibility, refer to the Application Engineering practice, FJTU-320-515-120.

CAUTION:Traffic may be affected if Release 9.1 or 10 units are mixed with Release 11 units using synchronization status messaging or if the NE uses Release 11 for the ethernet port mapped bridge or DS3 UNI cell relay.

18.7 Availability



In addition to providing front panel LEDs, the SV1A units provide equipment failure and unit-removed alarm and status messages through the craft and OSS interfaces.



19: Timing Control and Access (TCA) Unit

19 Timing Control and Access (TCA) Unit

19.1 General

This section describes the functions of the FLM 150 ADM Timing Control and Access units. There are two versions of this unit, the TCA and the TCA-ENH (enhanced) version. These units provide synchronization timing to other units in the FLM 150 ADM shelf. These functions are generated from the external building integrated timing supply (BITS), line timing inputs, or from an internal ±20 parts per million (ppm) clock. The units also provide line build-out (LBO) for the external clock signal outputs and can be used in all FLM 150 ADM configurations. The TCA-ENH unit supports synchronization status messaging and can be used in all FLM 150 ADM configurations.




19.2 Features

Table 19-1 lists the TCA and TCA-ENH unit(s) and associated supported features.

a An NE equipped with a TCA-ENH unit and Release 11R or earlier versions of the SV1A/MP1A units with any version of the HS1A unit.

b An NE equipped with a TCA-ENH unit and Release 11Q/S enhanced versions of the SV1A, the MP1A, and the HS1A-AD1 units.

The TCA/-ENH unit provides synchronization timing to other units in the FLM 150 ADM. It provides both automatic and manual switching, holdover functions, and DS1 Superframe (SF) or Extended Superframe (ESF) external output capabilities. These enhanced features allow the TCA/-ENH unit to provide synchronization distribution.

The unit receives the primary and secondary BITS input signals. If the primary timing fails, signals are automatically switched to a secondary timing reference. If both primary and secondary timing fails, self timing is derived from the internal clock to maintain system timing. The internal clock maintains a minimum ±20 ppm, long-term, free running accuracy. A holdover function is provided to maintain system timing if all referencing timing is lost. The clock input from the BITS is synchronized into a DS1 SF or ESF all-1s format.

The TCA/-ENH unit also provides incoming EC-1/OC-3/OC-12 signals from GP1,2,4, and 5 (line timing) as external timing reference. Frequency of the transmitted OC-3/OC-12 signal depends on network configuration. A microprocessor is provided for retiming DS1s from the internal clock.

The unit selects the best available timing reference using synchronization timing messages.

Note: Before removing a working TCA /-ENH unit, a manual switch from the Working to the Protect unit should be performed to prevent bit errors. A manual switch from the current “online” TCA /-ENH unit should be performed using the TL1 command OPR-PROTSW-EQPT:TID:AID:CTAG::MAN. The AID should indicate the unit being switched from.




Figure 19-1 shows a functional block diagram of the TCA/-ENH unit.

20: Time-Slot Assignment (TS1A) Unit

20 Time-Slot Assignment (TS1A) Unit

20.1 General

This practice describes the functions of the Time-Slot Assignment (TS1A) and Time-Slot Assignment–Enhanced (TS1A-ENH/-ENH2) units as they are used in the FLM 150 ADM system. The TS1A units provide time-slot assignment (TSA) and path switching functions for VT1.5 and STS-1.

20.2 Features

Table 20-1 lists the TS1A, TS1A-ENH, TS1A-ENH2 unit(s) and associated supported features.




Note: The TS1A-ENH2 unit is supported with Release 12S and later for the FLM 150 ADM.


The primary function of the TS1A unit is to provide time-slot assignment to incoming and outgoing VT1.5 signals.

The TS1A units allow any VT1.5 or STS-1 signal from the incoming high-speed lines to be cross-connected to any channel of any low or middle-speed groups.

Figure 20-1 shows the functional block diagram of the TS1A unit.

The TS1A-ENH unit provides additional functionality to the original TS1A. When equipped with the TS1A-ENH unit, the FLM 150 ADM allows the user to groom VT1.5 signals into tributary OC-3 and EC-1 interfaces. With the original TS1A unit, VT grooming was provided only for low-speed groups configured for DS1 or OVTG interfaces. For OC-3 and EC-1 interfaces, cross-connections can only be at the STS-1 rate.

The TS1A-ENH unit eliminates the interface restriction by allowing VT1.5 cross-connection from any high-speed STS-1 to any low-speed group regardless of tributary interface types.
