This section provides a brief overview of Models 120S and 120I. The Model 120 servers use tsame software and are based on the same design, CPU, and hard drives, and but have differeservice card configurations.

Both servers include a floppy drive that uses 3.5-inch double-sided, high-density diskettes. the floppy drive to install, reconfigure, andpatches or RSDs, and b

Hard disks provide storage for the operating system, system software, mailbox and message statistics, and digitized speech. The Model 120 uses a SCSI bus and SCSI disks.

In both servers, the telephony interface, voice recognition, and Fax cards support the Multi-Vendor Integration Protocol (MVIP) bus.

ISA card slots, the floppy drive, and SCSI hard disks. This system accommodates up to eight ISA-compatible telephony interface cards (analog or digital) for a maximum of 60 ports. Up to four SCSI disks of the same size provide up to 960 hours of redundant speech storage. The base system includes a SCSI hard disk and interface card, a modem, and a minimum of four ports on one line card.

service cards and indicates which cards must be configured.

The servers use the Multi-Vendor Integration Protocol (MVIP) bus. MVIP hardware devices communicate with each other via the 40-pin MVIP bus cable that connects to the top of the MVcards. Some cards access only a sub

IP set of the MVIP data. The Resource Manager handles this

automatically when the cards are configured through the software.

1 Service Cards for NuPoint Messeng

The Resource Manager is a software utility that allows you to configure the telephony interface hardware and the fax card, allocate hardware resources, and manage MVIP usage to prevent conflict among different applications.

At startup, the Resource Manager reads the system configuration from the configuration files updates its database. It then invokes the hardware driver for each device in the configuration, initializes all devices, and downloads any software that the hardware needs. Next, it configures the MVIP clock and busy-out trunks on the card

When initialization is complete, the Resource Manager is ready to serve any application that needs to allocate and use the hardware resources. It allows each application to allocate

TR 1925 Phoneline Exceptions Technical Reference

This technical reference explains what Phoneline Exceptions are and how to configure them to control a particular line, a range of lines, or all lines installed in NuPoint Messenger servers using the NuPoint Voice application.



1 Introduction

Telephony parameters are set values that determine the characteristics of the telephony interface between the NuPoint Messenger server and the PBX or Central Office switch. The default values were chosen for each parameter to conform to the valid ranges for most PBXs. Certain PBX installations might require minor changes to one or more parameters to achieve optimal PBX interface with the server. When any default telephony parameter is changed, the system is said to have a phoneline exception (line exception, or LE). Different types of LEs are described below:

• Timeout parameters - LE timeout parameters help control port usage by minimizing the time between call-processing events. Each LE value is set to ensure that the first event completes successfully without allowing excess time to elapse before the next event starts.

• Incoming signal detection - Line card ports use these LEs to monitor the telephony interface and detect incoming signals.

• Output signaling adjustments - These LEs control the signaling and tones needed to dial out for pagers, message delivery, and off-system messaging applications.

• DTMF detection - The NuPoint Messenger server receives events in the form of DTMF tones. Some aspects of DTMF detection can be customized for individual line card ports.

• Greet command parameters - The greet command, used for call progress and line signal monitoring, is a general purpose software routine. It detects speech, recorded announcements, dead lines, and call-progress tones, such as ring back, busy, and reorder. When the NuPoint Messenger server software instructs a line-card port to "wait for a greeting," the greet command uses digital signal processors to detect tones and speech.

• Speech and silence detection during recording - These parameters work together to detect speech pauses, then stop the system recording when a pause occurs and restart the recording when speech resumes. This function can be enabled or disabled.

Since adjusting a telephony parameter can cause undesirable effects in other, seemingly unrelated areas, be sure that a modification is necessary before you make it. If you are unsure of the valid ranges for your PBX, contact your PBX vendor. This chapter lists default values for the parameters and describes the LEs that can be adjusted.

2 The Phoneline Exceptions Program

Any telephony parameter that is not set to its default value is a "phoneline exception." Depending on the purpose, an LE affects a particular line, a range of lines, or all of the lines installed in the server.

The defaults provided with the server conform to North American Signaling Standards and, under most conditions, provide adequate service. Before using an LE, troubleshoot to determine the specific problem, interpret any compatibility issues, and then determine if an LE can help resolve that problem. After making a change, test and retest all lines affected by the change.

The LEs listed here include all available for this release. Not all LEs are available in all releases and revisions of software. To determine which LEs are available on your system, reach the Phoneline Exception menu and run a default LE report.

LEs are available on a per port basis. Make sure that any changes made to one range of lines do not adversely affect the performance of other line groups on your system.

When you change telephony parameters, keep these points in mind:



• You enter the LE number (referred to as a command number), not the LE name, when you modify these parameters.

• You modify most of these parameters on a line-by-line, or a group of lines, basis. A few LEs set parameters for all ports on one card.

• When you use the "add line exceptions" menu option to change a parameter, the change takes effect for either the first or the second call received on that port after the change, depending on the specific LE.

• When you use the "cancel exceptions" menu option to reset any parameter to its default value, the change takes effect only after you reboot or reinitialize the system.

Reach the Phoneline Exceptions menu online from the System Maintenance menu. Use it to generate a report of phoneline parameters that are set to values other than their defaults; to change current phoneline parameters; to reset parameters for a particular line to the default values; and to obtain a report of all telephony parameters and their default values. It is recommended that before you make any changes to any LE, you print the phoneline exceptions report for reference purposes. For more information about using the Phoneline Exceptions menu to change the telephony parameters, see CP 7022 in the Installation and Service Manual.

3 List of Phoneline Exceptions

This section lists and describes the LEs that are available on the NuPoint Messenger servers. Some LEs are duplicate functions. In these cases, use the lower numbered LE.

Note: Not all LEs are used. The numbering gaps are intentional. In addition, LEs 826 through 843 apply only to R2 signaling. See the R2 Integration Manual for more information on R2 signaling.

1 Start Record No Speech Time

What to Enter: Value in seconds between 0 and 16

Default: 5

How it Works: Sets the time between the end of the record beep and playing of the prompt "nothing recorded" when no speech is detected.

Tips & Techniques: Check the effect of this LE by logging into a mailbox, pressing M to make a new message, entering the mailbox number for the message, and then noticing the time between the end of the record beep and the prompt "nothing recorded." This time period is equal to the value of LE 1. Too short a time causes recording to end before the caller starts speaking. Too long a time ties up ports waiting for speech, even if the caller disconnects before starting to speak.

2 Stop Record Timeout


Default: 3

How it Works: Sets the time between end of speech when recording a message and playing of the prompt "end of message."



Tips & Techniques: Check the effect of this LE by setting it to some value, logging into a mailbox, pressing M to make a message, entering a mailbox number for the message, recording a message, and then noticing the length of time between the end of the message (speech) and the prompt "message complete." That time period is equal to the value of LE 2. Too short a time causes recording to end when the caller pauses between words or sentences. Too long a time ties up ports waiting for more speech after the caller disconnects.

3 Dial Tone Detect Time


Default: 2

How it Works: Sets the number of seconds of continuous energy required to detect dial tone. During all states, actual time is twice the set value.

Tips & Techniques: If this value is 1, false dial tone detection is possible. If this value is too large, any process requiring dial tone detection (such as paging, message delivery, or Auto-Wakeup) requires excessive time to detect dial tone. The server disconnects if a dial tone is detected during any process where it is not expected (disconnect supervision). Set to 0 (zero) to disable dial tone detection for R2 signaling and DID or tie lines that do not have dial tones. For NP TDD, set to 15 seconds in the NuPoint Voice Modify menu, TDD Options submenu.

Interactions & Limitations: LEs 3, 22, and 136 all have control over dial tone detection. This LE sets the number of seconds of continuous energy detected. LE 22 plus this LE gives the total time before the port times out (out-dialing, only). LE 136 sets the power required to validate the dial tone.

See Also: LEs 22 and 136 for more information about dial tone detection.

4 Pause Compression Enable

What to Enter: 0 for Disable, or 1 for Enable

Default: 1

How it Works: Enables or disables silence elimination. When enabled, the time between speech is not recorded if the silence lasts more than half a second.

Interactions & Limitations: Disabling this LE can cause a significant amount of your hard disk to be used to record the silence between spoken words and phrases, but it preserves the entire message with pauses.

6 DTMF Detect Enable


Default: 1

How it Works: Enables or disables DTMF detection on a port. If you set this LE to 0 on a port,



that port no longer recognizes any DTMF tones.

Tips & Techniques: Can be used in an Audio Text application where, for security purposes, no user input is allowed.

8 Dead Line Timeout


Default: 50

How it Works: Sets the time to wait for the presence of ringing, busy, or speech during a greet command. An event is sent when a line is totally silent after executing a greet command to determine that the line is dead.

Tips & Techniques: Reduce this value if the PBX does not give disconnect supervision.

See Also: FCOS bit 17 for quicker disconnect.

9 Ringing Timeout


Default: 15

How it Works: Affects outgoing calls. Sets the time that must elapse, after ringing has started, before the server considers an out-dialed call "Ring No Answer." You can change this parameter if these two conditions are present:

• NP Receptionist is installed.

• An outside caller is automatically forwarded to the NuPoint Messenger server after a certain number of rings.

Tips & Techniques: The value should be at least two seconds less than the value of call forward busy and no answer on your integrated PBX.

Note: This timer also affects the time a pager outdial rings a phone for message delivery and NP WakeUp.

10 Silence Timeout

What to Enter: Value in hundredths of a second between 0 and 255

Default: 75

How it Works: Sets the time of silence after incoming speech terminates that qualifies the end of speaking. After this, the greet command stops and an event is generated. This field should not require changing, but might be reduced slightly to improve response time.

See Also: LE 182. See the Greet Command section for more information on setting this field.



11 Speak Timeout


Default: 3

How it Works: Sets the time for the called party to stop speaking during a greet command. This field should not require changing.

Tips & Techniques: Speech and modem carrier tones that last a long time can cause the greeting to fail and the system to treat the call as a failure.

See Also: LEs 10 and 182. See the Greet Command section for more information.

12 MF Detect Enable


Default: 0

How it Works: If enabled, detects MF tones (North American Standard).

Interactions & Limitations: Do not change this field. The application automatically enables and disables MF detect before and after call setup. MF detect is disabled during voice mail activity. It is used only for call setup.

See Also: LE 31.

13 Enable AGC


Default: 1

How it Works: The automatic gain control (AGC) adjusts weak and strong signals to make the output level constant.

14 Pulse Per Second

What to Enter: One of following settings:

0 = 10 pps, 60-40 duty cycle 1 = 10 pps, 66-34 duty cycle 2 = 20 pps, 66-34 duty cycle

Default: 0

How it Works: Defines the pulse per second rate for dial pulse output. Adjust this parameter when the receiving equipment does not conform to North American Signaling Standards.



22 Start Dial Tone Timeout


Default: 8

How it Works: This value plus the value of LE 3 equals the time before a port times out when a dial tone is not present. For out-dialing only.

Interactions & Limitations: LEs 3, 22, and 136 all control parts of dial tone detection. LE 22 plus LE 3 gives you total time before the port times out. LE 136 sets the power required to validate dial tone.


23 Flash Hook Time


Default: 50

How it Works: Sets the time that the server remains on-hook during flash. When changing this field, start by adjusting it to the halfway point of the PBX min/max flash detect time (the default average on most telephone equipment is 60 to 65 hundredths of a second).

Tips & Techniques: Intermittent or complete transfer failures can occur if flash hook time is too short. If the calling party complains about hearing DTMF tones during transfer, this value is too low. If the value is too high, the PBX interprets it as a disconnect and drops the call.

Interactions & Limitations: For systems that run Centrex Integrations, set this LE to 100 (1 second) to allow operator transfers from the server or if the NP Receptionist feature is installed.

24 Wink Start


Default: 1

How it Works: Enables or disables a 200 ms off-hook condition that the line card sends after an incoming call is verified. It works for DID and E&M connections only.

Tips & Techniques: If you are installing a line with no dial tone to a pager outdial group, you might need to enable wink start. Wink start is a type of out signaling capability. In DID applications, wink start is usually required by the Central Office. Certain PBXs also require wink start signaling on E&M tie trunk connections.

25 Enable DTMF Column 3




Default: 0

How it Works: Enables detection of fourth column DTMF tones (A, B, C, D).

Tips & Techniques: Used only for special applications such as AMIS.

31 MF Receive Debounce Time

What to Enter: Value in milliseconds between 0 and 255

Default: 20

How it Works: Sets the time that an MF tone must last to be recognized as a valid digit.

32 DTMF Receive Debounce Time

What to Enter: Value in milliseconds, set in increments of 10, between 33 and 153

Default: 33

How it Works: Sets the time a DTMF key must be held down to be recognized as a valid NuPoint Voice command.

Tips & Techniques: Check the effect of this LE by pressing the DTMF keys and noticing how long you must hold down the key before the system responds. For example, if this value is 43 ms, DTMF keys must be held down 43 ms before the system responds. This LE is active at all times, except when playing or recording a message. Normally, this does not require adjustment.

33 Record DTMF Receive Debounce Time


Default: 63

How it Works: Configures how long a DTMF key must be held down while recording a message or greeting before the system recognizes the DTMF key.

Tips & Techniques: Check the effect of this LE by logging into a mailbox and recording a message. While recording the message, press a DTMF key and notice how long you must hold down the key before the system responds. For example, if this value is set to 43 ms, DTMF keys must be held down for 43 ms before the system responds. Some electronic telephone sets provide only a short burst of tone to the voice mail port, regardless of how long a DTMF key is pressed. Check this at the voice mail port.

Interactions & Limitations: This LE is purposely set higher than LE 32 to prevent false DTMF detection.



34 Play DTMF Receive Debounce Time


Default: 63

How it Works: Configures how long a DTMF key must be held down during playing of a message (and the prompt "end of message") or during review of a recorded message before the system recognizes the DTMF key.

Tips & Techniques: Check the effect of this LE by logging into a mailbox and playing a message. While playing the message, press a DTMF key and notice how long you must hold down the key before the system responds. For example, if this value is set to 43 ms, DTMF keys must be held down for 43 ms before the system responds. Some electronic telephone sets provide only a short burst of tone to the voice mail port, regardless of how long a DTMF key is held down. Check this at the voice mail port.

Interactions & Limitations: This LE is purposely set higher than LE 32 to prevent false DTMF detection.

35 Sleep After Hang-Up


Default: 2

How it Works: Time after hanging up that a port ignores an incoming call or a ringing event.

Tips & Techniques: Raise this value if the system answers with the caller’s menu or the "I do not understand that command" prompt. Too high a value results in poor use of ports and a perception of Ring No Answer problems or general greetings when using integrations.

Interactions & Limitations: For R2 signaling, set to 0.

See Also: LE 140. This LE overrides LE 140 if this LE is set higher.

38 Centrex Time Out


Default: 7

How it Works: Time that the system responds after seeing ringing or a data packet on a configured Centrex line. If ringing occurs on a port configured for Centrex and there is no data packet associated with that port within the configured time for this LE, the system answers with a general greeting instead of the mailbox greeting. If the data packet occurs first, the system waits the configured time for ringing. If that does not occur, the system invalidates the first data packet, restarts the timer on the ringing event, and waits the configured time again for data.

Other Requirements: The Centrex Optional Feature software must be installed.



Tips & Techniques: DMS 100 sites require a minimum of 10 seconds.

39 Pause Before Answer


Default: 0

How it Works: Time that a port delays before answering a ringing line.

41 Pause Before Dial Pick Up String


Default: 100

How it Works: Used with pickup-type integrations. Enables configuration of the delay between going off-hook and dialing the pickup feature access code.

42 Centrex Ring Timeout


Default: 7

How it Works: For the Centrex integration, if a data packet is received but a corresponding ringing event is not detected during this window, a Centrex ring timeout occurs and an error message is logged into the system logfile. This can occur if a caller hears the call being forwarded and decides to hang up. The data packet has already been received at this point, but there is no ringing event to match the data packet.

Other Requirements: The Centrex Optional Feature software must be installed.

Tips & Techniques: If this value is too low, it can result in the general greeting; if it is too high, it can result in the call being answered with the wrong mailbox greeting.

43 Answer Supervision Timeout


Default: 20

How it Works: Time that the line card waits to receive a ringing event when the dial string includes an "L." "0" means "wait forever."

Other Requirements: "L" must be in the dial string.



128 Minimum Busy Half Cycle (Non-Greet)

What to Enter: Number of half cycles between 2 and 255

Default: 25

How it Works: Minimum number of half cycles for busy or reorder detection. Not used when a greet or play command is active.

Tips & Techniques: Can be reduced if necessary to coincide with the PBX time for busy or reorder tone.

129 Minimum Busy Half Cycle (Greet)

What to Enter: Value in half cycles between 2 and 255

Default: 15

How it Works: Minimum number of half cycles for busy or reorder detection. Used only when the greet command is active.

Tips & Techniques: Can be reduced if necessary to coincide with the PBX time for busy or reorder tones.

131 Loop Break Detect Time

What to Enter: Value in hundredths of a second, between 0 and 255

Default: 75

How it Works: Time needed for the server to detect a line break (disconnect).

Tips & Techniques: If the PBX goes on-hook for a longer interval, NuPoint Voice considers it a disconnect and goes on-hook.

133 Delay Before Wink


Default: 20

How it Works: After a valid incoming seizure, the port waits this time before sending the wink start signal. It is active only when the line card is set to DID or E&M, or when wink start is enabled.

136 Minimum Call Progress Tone Detect Power

What to Enter: Value between 10 and 255



Default: 103 (about -41 dBm)

How it Works: Minimum power required to validate call progress tones, such as dial, busy, reorder, pagers, and ring back.

Tips & Techniques: Calculate the value as dBm = 0.11 (value) - 52.


140 No Break/Ring Time On Loop


Default: varies by trunk type:

• 200, Ground Start

• 75, Loop Start

• 0, DID/E&M

How it Works: Time that line breaks are ignored after off-hook.

Interactions & Limitations: If LE 35 is present, that value overrides this LE.

See Also: LE 35.

142 Inhibit Play Time


Default: 50

How it Works: Sets the time before a port begins to play the first prompt after answering.

Tips & Techniques: For integrations that use DTMF signaling, this LE can be increased, if necessary, depending on DTMF interval timing. If the beginning words of mailbox greetings are being cut off, increase this value. For NP TDD, set to 100 in the application menus.

144 In-Ring Off Time


Default: 75

How it Works: Time that the incoming ringing current must be off before a valid ringing event is returned.

Tips & Techniques: If you want distinctive ringing, set this value to 50. See LE 148 for other ringing information.



Interactions & Limitations: LEs 144 and 148 control incoming ringing detection.

See Also: LE 148.

148 In-Ring On Time Low


Default: 1

How it Works: Minimum time for an incoming ring burst to be considered valid.

Tips & Techniques: If you want distinctive ringing, set this value to 50. LEs 144 and 148 control incoming ringing detection.

See Also: LE 144.

154 Pulse-Out Interdigit Delay


Default: 75

How it Works: Length of time between accepting a pulse output command and starting the pulse output of digits.

156 Record Prompt (Beep) Duration


Default: 20

How it Works: Time for the record prompt beep. The following three LEs control the record prompt beep:

• LE 156 controls length of beep.

• LE 158 controls frequency of beep.

• LE 178 controls output level of beep.

See Also: LEs 158 and 178.

158 Record Prompt Frequency

What to Enter: Frequency in Hertz between 200 and 3600

Default: 1000

How it Works: Sets the frequency of the record prompt beep. The following three LEs control



the record prompt beep:

• LE 156 controls length of beep.

• LE 158 controls frequency of beep.

• LE 178 controls output level of beep.


161 Pause Compression: Silence Threshold Level 24/32 Kbps


Default: 32

How it Works: When pause compression is enabled for 24/32 Kbps, sets the level that is treated as silence. When the number of consecutive frames set by LE 163 occur below this level, those frames are not recorded.

Tips & Techniques: Calculate the value as dBm = (value - 89) * 2/3.

See Also: LE 163.

WARNING! Do NOT change this phoneline exception. Changes are not supported for this phoneline exception.

Silence Threshold Level 18 Kbps


Default: 32

ber of consecutive frames set by LE 163 occur below this level, those frames are not recorded.

For the two-, four-, and eight-port cards, use the provided cables.

For the 16/32-port interface with unbalanced serial connections, use shielded, low-capacitance cables that are designed for serial data ure noise immunity.

Hard Disk Types

This section discusses how to configure the Master and Slave jumpers on an IDE hard disk.

CAUTION! Set only the Master/Slave IDE jumpers. Other default jumper and switch settings are for reference purposes. Do not change them without specific instructions from your support representative. Failure to comply with this warning can result in total, unrecoverable Hard Disk Failure.

An IDE drive can be jumpered as any one of the following:

• As Master in single disk configuration

• As Master in a two-disk configuration

• As Slave in a two-disk configuration with an existing master disk

When installing a hard disk, verify the Drive Manufacturer and Model Number that are printed on the hard disk. Wear a properly grounded wrist strap to avoid component damage. Turn off the power to the system before starting the work. Follow all ESD procedures when handling system assemblies.





The disk is pre-configured at the factory and it is ready to install. However, it is a good field practice to double check the disk configuration. Before you install a new disk, check the following:

• Read the Technical memo for the hard disk. It gives information on how to set the Master/Slave jumpers on the disk.

• Refer to the Installation and Service Manual for instructions on how to remove and replace disks.

TR 1936 SCSI Hard Disk (Model 640) Technical Reference

This technical reference provides information for the SCSI hard disks used in the NuPoint Messenger server Model 640. It provides guidelines for basic configuration and installation.

The Model 640 uses hard disks to store the operating system, speech, names, greetings, prompts, messages, and application programs for system functions. Additionally, all disks use the Small Computer System Interface (SCSI) bus to interface to the system.


This section provides general information about SCSI disks used with the Model 640. For information about a specific disk, consult the original documentation, including Technical Memos. If you still have questions, contact your support representative.

In the Model 640 storage assembly, the SCSI ID for a disk contains two digits. The first digit identifies the module number. The second digit identifies the slot that the disk is installed in. There are no jumpers to set on the disks.

Figures 1 through 8 in this section show the disk configuration and pairing with SCSI IDs for one, two, three, and four module systems. The first three modules must include at least one primary (active) disk. Each matching redundant disk resides on a different module than its primary. This protects speech and records if a module crashes.

Use the following guidelines when installing a hard disk.

CAUTION! In the Model 640, there are no jumpers for setting the SCSI ID. Do not change the SCSI ID jumper configuration.

1. Identify the model number of the hard drive. Refer to the Technical Memo for the hard drive,

then refer to the disk illustration for the hard drive.

2. Remove all internal SCSI disk terminators. In the Model 640, the SCSI cable is terminated externally.

List of Technical References Power and Grounding Requirements -----------------------------------------------TR 1900 AMPS Power Supply --------------------------------------------------------------------TR 1926

TR 1900 NuPoint Messenger Server Site Planning Power and Grounding Requirements

This technical reference contains power supply and grounding requirements for the NuPoint Messenger server Models 640, 120, and 70. To ensure a safe and successful installation, It is recommended that the power and grounding for the servers meet these requirements.

Note: For information regarding international power and grounding requirements, contact your distributor.

WARNING! The power and grounding information in this document is not intended to take the place of the country electrical codes and local practices for your area. All site wiring must comply with country and local electrical codes.

1 Facility Power Requirements

Transient power disturbances can degrade the system performance. These are caused most often by heavy machinery such as air conditioners and elevators or copy machines and other office equipment. Therefore, provide a dedicated circuit with an isolated ground for the server to minimize this type of disturbance.

AC installations in the United States require a standard 3-prong, 110 VAC, isolated ground (IG) receptacle. Locate the receptacle within 3 ft. (1 m) of the server to eliminate the need for an extension cord. Elsewhere, terminate the power cord with an approved power plug that mates with the isolated ground receptacle approved for your country.

Isolated Ground Requirements



WARNING! The server must be grounded correctly to ensure personnel safety and proper system operation. The chassis ground terminal on the server must be connected to the correct ground source to ensure personnel safety and proper system operation.

Use an isolated ground for the server. See Figure 1. Verify that resistance and impedance between the server and the master ground bar (MGB) equals less than 1 Ω. Verify that the voltage between the server and the MGB equals 0 V. Verify that the current equals 0.1 A RMS or less when all telephone lines are idle.

Figure 1 Typical 110-VAC Single Phase Receptacle

Use a separate circuit for each Model 70 or 120 server. For optimum reliability, use two separate circuits for each Model 640 module, one for the CPU and one for the Storage assembly. See Figure 2.

Note: In this document, a module is the functional unit in a Model 640 that includes a CPU assembly, the CPU Power Supply, and a Storage assembly. The Storage assembly has a separate built-in power supply. A server comprises one or more modules.

The 120/240VAC power connection for the Model 120 is similar to a typical computer. The DC power terminals provide input for -48VDC. See Figure 4.

Always connect the chassis ground to an isolated ground before connecting power during installation. It provides the safety ground and a return path for spurious currents due to voltage transients induced by electromagnetic fields near inter-assembly cabling and other electrical wiring. See Figure 4.



CAUTION! Check that the AC power supply voltage selector is correctly set for 110VAC or 220VAC before plugging the Model 120 into a dedicated circuit.

Figure 4 Model 120 Power Connections

4 Model 640

The Model 640 will be in one of four possible configurations of AC or DC power in an open frame (rackmount) or an enclosure.

Note: For optimum reliability, use two dedicated circuits with an isolated ground for each module in the system.

The AMPS Assembly for the Model 640 internally generates -48V for analog telephony ports, only.

Note: Talk batteries provide a low noise, 48V power source used exclusively for analog telephone ports (Tip, Ring, and E&M leads).

When analyzing the power requirements, consider the following:

• Run the line (L), neutral (N), and ground (G) conductors in the same conduit. If a conduit is not used, be sure to use an insulated ground wire to connect the panelboard chassis to the MGB.

• Isolate the N and G buses from the panelboard chassis.

• Do not strap the N and G buses together at the panelboard except at the main incoming service panel or at the first point of distribution after the output of the service transformer that feeds the main electrical service panel. If the MGB bonding is not accomplished within the transformer, it can be bonded at the first point of distribution.



• From the customer's electrician, obtain written verification of the MGB bonding and a procedure for checking all connected output panelboards to ensure that only one neutral-to-ground bond exists. This eliminates the possibility of ground loops.

• In the U. S., ensure that all outlets are conventional National Electrical Manufacturer’s Association (NEMA) IG receptacles with only one duplex receptacle per dedicated circuit.

For optimum reliability and to ensure NP CSO (CSO) of Model 640 modules, use a dedicated branch circuit with isolated ground for each CPU assembly and each Storage assembly.

Figure 2 shows typical branch circuits that supply dedicated 110VAC circuits from the equipment-room power panelboard.

AC Grounding Requirements

WARNING! The ground terminals on the CPU assembly must be connected to the correct ground source to ensure personal safety and proper system operation.

The CPU Power supply, described in TR 1926, includes the following three ground connections:

Logic Ground (LG): Provides the ground reference for the logic levels used by various active components on the circuit cards.

Chassis Ground (CG): Provides a return path for spurious currents that might reach the chassis as voltage transients induced by electromagnetic fields from nearby electrical wiring.

-48V Talk Return (TR): Provides the ground reference for the telephone circuits.

Open Frame Connections

When installing the modules in an open frame system, make the ground connections as shown in Figure 5. Deviating from this may cause grounding problems.

Note: Figure 5 uses these additional terms: Ground Window Bar (GWB) and Talk Ground Window Bar (TGWB).

Figure 5 Model 640 --AC Power and Grounding

For an open frame system, use 6 AWG (26,3000 circular mils), or better, stranded copper cable for the following connections:

• CG between each open frame and from one open frame to the GWB for the site

• TR terminal strip to the TGWB for the site

• LG terminal strip to the GWB for the site

Enclosure Connections

Each enclosure for AC systems includes a Power Distribution Panel (PDP) that provides connections to the NuPoint Messenger components and to the site ground connections. See Figure 6.



Figure 6 AC Power Distribution Panel

All power and ground connections within an enclosure are prewired at the factory.

In all enclosures for AC systems, the PDP provides an AC to DC power supply with separate power switch that provides 48 VDC to the fans in the top of the enclosure.

In the first enclosure, the PDP provides the following:

• One 2-position terminal block connects LG and TR from the module(s) in the enclosure to the back of the PDP and from the front of the PDP to the Master Ground Bar (MGB).

• Studs on the front and rear provide CG connections. Each assembly unit in the enclosure connects to the stud at the rear. The stud on the front connects to the MGB for the site.

In the second enclosure, the PDP provides one 2-position terminal block that connects LG and TR from the module(s) in the enclosure to LG and TR on the back of the PDP in the first enclosure.

A ground braid mounted near the top of the enclosures provides the CG connection between two adjacent enclosures in the same system.

DC Requirements

Systems that use -48 VDC power require a power distribution panel between the power source and each module. For optimum reliability, use a separate, dedicated circuit with isolated ground through a fuse or circuit breaker for each module in the Model 640.

DANGER! Be certain that the external breakers are set to OFF or the fuses are removed from the main distribution panel before installing the terminal lugs or connecting the power leads.

Table 5 lists specifications for the DC system power. For optimum reliability and to ensure NP CSO (CSO) of server modules, it is recommended that each CPU assembly and each Storage assembly has a dedicated branch circuit with isolated ground.

TR 1926 AMPS Power Supply Technical Reference

This technical reference provides information about the Alarm and Monitor Power Supply (AMPS and AMPS II) for the Model 640.

1 Description

The Alarm and Monitor Power Supply, AMPS and AMPS II, are AC or DC power supply assemblies used on Model 640 servers.

Physical and Electrical Characteristics

The AMPS assembly conforms with standard EIA-310, Racks, Panels, an Associated Equipment and Bellcore TR-NTW-000063, Network Equipment - Building System (NEBS) Generic Equipment Requirements.



The AMPS unit occupies 3U (5.25 in. or 13.5 cm) in a 19-inch enclosure or open frame. The AMPS II unit occupies 2U (3.50 in. or 9 cm). All units measure 16.88 in. (42.9 cm) wide and 12 in. (30.5 cm) deep.

Note: The EIA RS-310-C Standard defines one modular unit (U) as 1.75 inches (4.5 cm).

AMPS assemblies use either AC or DC power. AC assemblies use 90 - 131V or 180 - 264V at 47 to 63 Hz. DC assemblies use 42 - 56 VDC. Each AMPS assembly powers and protects one CPU assembly and one CSO/IO Assembly. Table 1 shows the DC outputs, current levels, and protection devices.

Table 1 DC Output Over-Current Protection Voltage Current Protection Device

+5V 60 A absolute maximum

Factory set on Electronic Circuit Breaker (ECB)

+5V Set point value Programmed on ECB at power-on by operator

+12V 15 A Power supply assembly -12V 5 A Power supply assembly -48V 4 A Power supply assembly

Connect each AMPS assembly to a single branch circuit with a 20 Amp AC or DC circuit protector.

Filter-fan units cool the power assembly and protect the interior from dust particles larger than 30 PPM. The AMPS unit includes one filter-fan unit. The AMPS II unit includes two filter-fan units.

The AMPS and AMPS II assemblies provide safety (frame) ground connections. The customer must provide an adequate fault path to ground beyond the NuPoint Messenger system. Follow the recommendations of the National Electrical Code and comply with all ordinances for your location in order to provide an adequate safety ground for the AMPS or AMPS II assembly.

2 Functional Overview

The AMPS or AMPS II assembly monitors and regulates the system electrical voltage and current levels, fan functionality, and system temperature. It also detects blown fuses, monitors the server, and displays visible alarms when it detects conditions detrimental to the server.

The AMPS or AMPS II assembly provides two monitors. An Electronic Circuit Breaker (ECB) monitors the output current to the system. The Fan Monitor Board (FMB) checks fan operation. Under software control, the FMB and ECB work in conjunction with an internal, module-control card to monitor the power supply assembly, fan operation, and temperature. The cards also provide visible lights for Critical, Major, and Minor alarms.

The server can operate continuously because the AMPS or AMPS II assembly monitors the system power and cooling and provides alarms. Online monitoring reduces system maintenance and decreases diagnostic time if a fault occurs. This increases system reliability, availability, and serviceability.

Electronic Circuit Breaker (ECB)



The ECB monitors the +5V current for over-current (Max current), undercurrent (Fault), and programmable delta current (Delta Monitor) levels. Deviations from specified limits are indicated on the front panel of this assembly. Deviations are also communicated through the rear panel AUX port for custom connection to a Site Event Buffer or other, similar device. In multi-module environments, the ECB communicates deviations among power supplies for each module.

In AMPS units, the ECB is a field-replaceable, plug-in card that resides beside the FMB module in the power supply assembly. In AMPS II units, the ECB is integrated into the power supply.

Fan Monitor Board (FMB)

The FMB monitors and enables alarms in single- or multi-module servers. It provides alarms for voltage levels, temperature, and fan rotation.

In AMPS units, the FMB is a field-replaceable, plug-in card that resides beside the ECB module in the power supply assembly. In AMPS II units, the FMB is integrated into the power supply.

Voltage Monitor Features

Within each module in the server, ±5V, ±12V, and -48V in the AMPS or AMPS II assembly and +5V and +12V in the Storage Assembly are monitored.

In addition, the AMPS unit provides test points on the front panel for manually measuring the +5 V, +12V, -12V, and -48V outputs.

In a multi-module server, the +5V output on each power supply is monitored so that the other modules can sense when the +5V logic power is disrupted for any CPU. This supports NP CSO (CSO), which is an optional feature. If a power supply problem causes the Master Module to fail, CSO allows the Master Module software to move to another module.

Fan and Temperature Monitor Features

The FMB monitors the rotation sensor on each fan. An alarm signals when the fan rotation falls outside of the limits set on the FMB. The FMB also monitors the temperature in each module. An alarm signals when the internal temperature exceeds 50°C.

Rear Panel ALARM I/O

Four DB9 connectors located on the rear panel provide alarm input/output (I/O). The ECB IN and ECB OUT connectors carry Max, Delta, Fault, and +5V alarms to other modules in a server. The AUX connector allows a remote connection to a Site Event Buffer or similar device to provide external site-event monitoring functions. A fourth connector carries voltage, fan, and temperature signals from the Storage Assembly for processing.

Power and Grounding

External wiring provides power and ground to the AMPS or AMPS II assembly. Use a dedicated circuit with an isolated ground for each power supply.

The rear panel includes an AC input terminal for AC units or a DC input terminal for -48V DC units. The use of a 20 Amp circuit breaker for each branch is recommended.

The rear panel provides three ground connections: Chassis Ground (CG), Logic Ground (LG) for digital logic levels, and -48V Talk Return (TR) ground for analog signals.



All power and grounding terminal blocks on the AMPS and AMPS II assemblies use #6 terminal block screws. For connecting wires to the terminal block, use crimp lugs that fit #6 studs.

For more information about power and grounding for the system with illustrations of wiring, refer to TR 1900.

3 Indicators and Controls

Switches, indicators, and controls for the AMPS and AMPS II assemblies are located on the front and rear panels of each unit.

WARNING! Disconnect the server from its power source before connecting any cables or components.

Before you install a new AMPS or AMPS II assembly:

• Read this entire Technical Reference

• Refer to the Model 640 Installation and Service Manual for instructions on how to remove and replace the AMPS assembly.

Note: After installing the AMPS or AMPS II assembly, or adding or removing components in a module, you must reprogram the Delta Monitor set point. Turn the power switch off, then hold the Program Current Level pushbutton in for 2 seconds while turning the power switch ON.

6 Maintenance Guidelines

The fan filters are located on the back of the AMPS or AMPS II assembly. In an office-like environment, inspect the filters every three months and replace them as needed. If the environment conditions of the site are less ideal, the optimal replacement interval may be shorter.

On the AMPS unit, remove the four screws that hold the EMI-filter assembly to the fan. The filter assembly is hinged on the left. Slide the old filter out, then slide the new filter in.

On the AMPS II unit, remove the four screws that hold the EMI-filter assembly to the fan. The filter assembly is hinged on the top. Slide the old filter out, then slide the new filter in.

2 Connecting Guidelines


Before you connect the console terminal, review the Specifications section above and refer to TR 1912 (Pentium CPU) or TR 1934 (486 MB) for information about Port 1, the console port for the server.

Follow these guidelines:

• To connect the video display unit, use the provided adapter and the cable that the customer provides.

• To use a dumb terminal, connect it directly to the console port.

• To use a PC, install Procomm 2.1 and the keyboard-driver file, then connect a "null-modem" cable to the console port. The null-modem cable swaps pins 2 and 3 of the interface



connection to emulate a modem connection.

After installing the terminal or PC, test it according to the manufacturer’s instructions.

TR 1932 Hardware Alarms MonitorTechnical Reference

This document provides information for the Hardware Alarms Monitor (HAM) used in the NuPoint Messenger server Model 640. It provides a brief description of the location of the alarm indicators, alarms configuration data, and guidelines for other HAM tasks you can perform. For more information on using the HAM software, refer to the Diagnostics Manual.

1 Introduction

The Hardware Alarms Monitor (HAM) software works with the Model 640 Module Control Board (MCB) II hardware alarms subsystem to serve as an alarms monitor for the voice mail system. The HAM software detects error events and posts those errors to the event log to assist in diagnosing system problems. HAM event counters track how many times each type of alarm occurrs.

When an error or alarm occurs, the alarm event causes the following actions:

• The event is posted to the NVRAM event log

• The event is posted to the system error logfile if this feature is enabled

• The event is counted and added to the alarm event counters

• Depending on the severity, the appropriate front panel indicator lights

• Depending on the severity, the audible alarm sounds if this feature is enabled

• The event triggers a continuous interrupt protection (CIP) limit, and the alarm is disabled if the CIP limit is reached

The NVRAM event log is non-volatile so that the alarm configuration and details are retained when the server is powered off.

The indicator lights are light emitting diodes (LEDs) on the MCB II board. The indicators also show on the front panel of the Alarm and Monitor Power Supply. Each indicator is triggered by a relay. If you want to, you can connect the relays to a peripheral device to trigger external alarms. These indicators are described below:

Alarm Severity MCB II LED AMPS Lamp Critical Red Red Major Yellow Amber Minor Green Yellow

Figure 1 shows the position of the alarm LEDs on the MCB II card and Figure 2 shows the position of the alarm indicators on the front panel of the Alarm and Monitor Power Supply (AMPS).

Figure 1 Alarm Indicator Lights on the MCB II Card

Figure 2 Alarm Indicators on AMPS’ Front Panel



2 Alarms Configuration Data

The HAM software is included with Release 6.1 software for all Model 640 servers that use the MCB II card.

Assigning Alarm Levels

The Assign Alarm Levels menu lets you assign an alarm level to a particular alarm condition. This assignment affects which indicator lights when the alarm condition is detected. You can assign the alarm level as critical, major, or minor. You can specify alarm levels for all alarms or separately for current fault alarms, fan fault alarms, power supply glitch alarms, MCB II memory parity error alarms, power supply surge alarms, power supply failure alarms, fuse alarms, and temperature alarms.

Table 1 shows the fault type and default settings for the alarm level classification.

Table 1 Default Alarm Levels Fault Type Minor Major Critical Audible Alarm

Power supply negative glitch

X

Power supply positive glitch X Current limits exceeded X X

Fan faults X X Power supply surge X X

Fuse faults X X Memory parity error X X Power supply failure X X X Temperature alarms X X X

Setting Audible Alarms

The audible alarm is also configured using the Assign Alarm Levels menu. By default, all major and critical faults trigger the audible alarm. You can change the fault level required to trigger the audible alarm. Table 2 shows the alarm level required to trigger the audible alarm, based on the level set for the audible alarm.

Table 2 Audible Alarm Trigger Levels

Audible Alarm Level

Fault Levels

Critical Major Minor Critical Enabled Major Enabled Enabled Minor Enabled Enabled Enabled

For example, if you set the audible alarm level to critical, then only faults of critical severity will trigger the audible alarm. If you set the audible alarm level to minor, then critical, major, and minor faults will all trigger the audible alarm.



3 HAM Guidelines

In addition to assigning alarm levels and setting audible alarms, the HAM software features allow you to perform the following tasks:

• Enable and disable alarms

• Set limits for Continuous Interrupt Protection (CIP)

• Enable alarms that have been automatically disabled by CIP

• Specify a default module to configure one module differently from other modules

• Initialize the event log and event counters and restore the default alarm configuration

• Reset the audible alarm, alarm event counters, indicators, and event log

• Reset alarms and indicators automatically after the fault is cleared

• Test the audible alarm and indicators

• Display, print, or save the alarm configuration, counters, or event log

Enabling and Disabling Alarms

You can enable and disable alarms using the Enable Alarms menu and the Disable Alarms menu. Using the menus you can enable or disable all current fault alarms or only the fan fault alarms, power supply glitch alarms, power supply surge alarms, power supply failure alarms, fuse alarms, and temperature alarms.

Setting Continuous Interrupt Protection

You can enable continuous interrupt protection (CIP), which determines when an alarm should be automatically disabled. Use the Enable menu to set CIP limits for the time period and number of faults. If the same alarm is reported the specified number of times within the specified time limit, the alarm is disabled.

You can specify a time limit of one second, one minute, or one hour, and a fault limit of two to nine. By default, the CIP time limit value is two seconds and the CIP fault limit value is three. Use the Disable menu to disable CIP. Also, the Reinstate Configuration options lets you re-enable alarms that have been automatically disabled by CIP.

Specifying a Default Module

The Host Selection menu allows you to perform functions on a specific module or to specify that functions apply to all modules. After you select a module, all subsequent functions apply only to the selected module. By default, all functions apply to all modules. Once a module is selected, that module remains selected for all operations until another module or all modules are selected. This option is useful when you want to configure one module differently from the others.

Initializing Alarms, Event Counters, and the Event Log

The Initialize menu restores alarm configuration default values. This menu also clears the NVRAM event log and event counters.

Resetting the Audible Alarm, Alarm Event Counters, LEDs, and Event Log

The Reset menu lets you reset the audible alarm, alarm event counters, the front panel LEDs, and the NVRAM event log.



The Reset Alarm Counters menu lets you reset all alarm counters or reset separately the current fault counters, fan fault counters, power supply glitch counters, memory parity error counters, power supply surge counters, power supply failure counters, fuse counters, and temperature fault counters.

The Reset Indicators menu lets you reset the LEDs for all panel indicators or reset separately the critical, major, or minor LED indicators.

The Reset NVRAM Event Log menu lets you clear the NVRAM event log for a specific module or modules. This feature is useful when you have corrected a fault and the fault history is no longer relevant.

Resetting Alarms Automatically

When an alarm turns on the appropriate indicator, the indicator remains lit until you reset it, even if you have cleared the fault that triggered the alarm. Optionally, you can use the Auto Reset feature to automatically reset an indicator after the fault that triggered the indicator has been cleared.

Testing the Audible Alarm and Fault Indicators

The Test menu lets you test and reset the audible and visual alarms. When you test the audible alarm, a message is displayed for three seconds which states you should be hearing the audible alarm. If the audible alarm is not working, the hardware switch settings might not be correct or the cables might not be connected properly.

Displaying, Printing, or Saving Alarm Information

The View menu lets you display, print, or save to a file the alarm configuration, alarm counters, alarm faults, or the NVRAM event log. All options from the View menu display the Report Output Routing submenu from which you can direct the requested information. The information can be displayed on your screen, sent to one of two serial ports for printing, saved to a file, or appended to a file.

TR 1933 Modems Technical Reference

For maintenance purposes, a US Robotics Sportster modem is recommended and shiped with NuPoint Messenger servers.

This technical reference provides information about configuring and using this maintenance modem with the NuPoint Messenger server Models 640, 120, and 70. For information about configuring and using a modem with an optional feature, such as NP Net, refer to the documentation for that optional feature.

1 Description

This section describes the serial port connections on the servers. It also gives cable descriptions and specifications.

Serial Ports

Each Model 640 module includes six standard serial ports, two on the CPU card and four on the



MCB II card. To add ports to a Model 640, use a Serial Interface card.

The Model 120 and Model 70 servers provide two standard serial ports. To add ports to a Model 120 or 70 server, use a Serial Smartcard or Serial Interface card.

For general light-duty and maintenance use, connect the supplied modem to Serial Port 2. If Serial Port 2 is already in use, connect the modem to a port on an optional serial interface card.

If the modem supports an optional feature application, connect the modem to a port on an optional serial interface card. For more information about using a modem with an optional feature, refer to the documentation for the specific optional feature.

Table 1 shows conventions for serial ports connections and locations for all servers.

2 Configuration Guidelines

Use the information in this section to configure your maintenance modem.

For most applications, configure the serial port device type as a modem.

Occasionally, the modem handling tasks do not start properly for remote access, so you may need to set the serial port device type as a null terminal.

Note: Do not leave remote access connected for extended periods. If you hang up before exiting from all menus, the active console may not close properly, placing the next modem user into the active console session.

Configuring as a Modem-Type Device

Use the following steps to configure a modem-type device at the server:

1. For the US Robotics Sportster modem, turn off the power for the modem and set only the following switches to ON:

- 3, Enable result code display

- 5, Disable auto answer

- 8, Smart mode AT command set recognition

2. Turn the modem power on.

3. From the Main menu, select System Maintenance, Additional Options, then the Console/Serial Port Setup menu.

4. Assign the serial port as a modem device and set it to 9600 baud.

5. Reboot the system to enable the new configuration.

Configuring as a Null Terminal-Type Device

Use the following steps to configure a null terminal-type device at the server:

1. For the US Robotics Sportster modem, turn off the power for the modem and set only the



following switches to ON:

- 1, Ignore DTR

- 4, Suppress keyboard echo

- 7, Use &F0 generic software setup at power on to ON.

2. Turn the modem power on.

3. From the Main menu, select System Maintenance, Additional Options, then the Console/Serial Port Setup menu.

4. Assign the serial port as a terminal device and set it to 9600 baud.

5. Reboot the system to enable the new configuration.

Note: When access as a terminal is no longer needed, reconfigure the serial port and modem as a modem-type device.



1. Before you connect the modem, become familiar with the material presented in the Specification section above.

CAUTION! The modem may require that the input signals be present on different connector pins. If so, purchase an adapter from a local dealer.

2. Use the cable that came with the system to connect the modem to the server port.

- Plug the 9-pin connector into Serial Port 2 (designated "SER2" in system software), using a DB9 gender converter if necessary.

- Plug the 25-pin connector into the modem.

3. To configure the modem software, reach the System Maintenance menu, Additional Options, then the Console/Serial Port Setup option.

4. After installing the modem, test it according to the manufacturer’s instructions.
