The following safety precautions must be observed at all times during operation, service, and repair of this equipment. Failure to comply with these precautions, or with specific warnings elsewhere in this manual, violates safety standards of design, manufacture, and intended use of this product. RFL Electronics Inc. assumes no liability for failure to comply with these requirements.

GROUND THE CHASSIS

The chassis must be grounded to reduce shock hazard and allow the equipment to perform properly. Equipment supplied with three-wire ac power cables must be plugged into an approved three-contact electric outlet. All other equipment is provided with a rear-panel ground terminal, which must be connected to a proper electrical ground by suitable cabling. Refer to the wiring diagram for the chassis or cabinet for the location of the ground terminal.

DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE OR IN WET OR DAMP AREAS

Do not operate the product in the presence of flammable gases or fumes, or in any area that is wet or damp. Operating any electrical equipment under these conditions can result in a definite safety hazard.

KEEP AWAY FROM LIVE CIRCUITS

Operating personnel should never remove covers. Component replacement and internal adjustments must be done by qualified service personnel. Before attempting any work inside the product, disconnect it from the power source and discharge the circuit by temporarily grounding it. This will remove any dangerous voltages that may still be present after power is removed.

DO NOT SUBSTITUTE PARTS OR MODIFY EQUIPMENT

Because of the danger of introducing additional hazards, do not install substitute parts or make unauthorized modifications to the equipment. The product may be returned to RFL for service and repair, to ensure that all safety features are maintained.

READ THE MANUAL

Operators should read this manual before attempting to use the equipment, to learn how to use it properly and safely. Service personnel must be properly trained and have the proper tools and equipment before attempting to make adjustments or repairs.

2.1 INTRODUCTION

This section gives a functional description of the IMUX 2000 M-DACS, including how the unit can be configured for point-to-point, drop/insert, or Bi-directional Line Switch Ring using electrical and/or fiber E1 interfaces. This section also defines all common equipment, connectors, switches, and indicators used in the IMUX 2000 M-DACS. It also briefly discusses the cross-connect and line-switch modes of operation of the DACS module.

2.2 MULTIPLEXER CONFIGURATIONS AND SYSTEMS

The IMUX 2000 M-DACS is a drop/insert multiplexer with Digital Access Cross-Connect (DACS) functionality. It can be fitted with an electrical E1 interface or an optical E1 interface using a variety of interface adapters. The optical interface adapters permit the E1 circuit to operate over a fiber optic cable and are available in both multimode and single-mode configurations at several different wavelengths.

M-DACS-E1 RFL Electronics Inc. June 19, 2006 2-1 (973) 334-3100


2.2.1 MULTIPLEXER FUNCTIONALITY

The multiplexer serves as an interface between E1 “high-speed” circuits and multiple voice and data “low-speed” circuits. Channel modules convert voice and data signals into single or multiple 64,000-bits/second (64-kbps) digital signals. These 64-kbps signals or “time slots” are then combined by time division multiplexing (TDM) into an E1 signal. The multiplexed voice and data circuit becomes payloads within the E1 circuit.

A single E1 circuit provides 32 full-duplex, 64-kbps time slots for an aggregate payload capacity of 2.048 Mbps in each direction. The time slots are numbered 0 through 31. Time slot 0 is reserved for system use, and if CAS (Channel Associated Signaling) is used, time slot 16 is dedicated to this function. Time slot 30 is used for fast reframe function, if enabled. See Section 10 for more information on E1 framing.

2.2.2 E1 TIME SLOT USAGE

The specification for the E1 system calls for 32 full-duplex 64 Kbps time slots, numbered 0 to 31, providing a data rate of 2,048,000 bps, or 2.048 Mbps. Time slot 0 is reserved for system use (framing information, CRC, etc.) and is not available to the user. This leaves a maximum aggregate payload capacity of 1.984 Mbps (31 time slots of 64 Kbps each).

Some applications, such as voice communications, require additional data such as ring, on-hook, or off-hook state to be associated with the payload. This additional information is referred to as signaling. In E1 systems this signaling information is passed between nodes using Channel Associated Signaling, or CAS. CAS utilizes time slot 16 to pass the signaling information for all time slots. The E1 specification calls for a multiframe structure within the data located in time slot 16 to allocate the signaling bits between time slots.

If CAS signaling is used anywhere in a network, it should be used throughout the network, thus precluding time slot 16 for user data. If CAS is not used in a network, time slot 16 may be used for payload traffic by selecting Common Channel Signaling (CCS) which will de-select CAS. Note, however, that this will prevent signaling information from passing between nodes.

The RFL fast reframe uses time slot 30. If fast reframing is required in a network, all nodes should have fast reframing enabled, and time slot 30 will be reserved. If all nodes have fast reframe disabled, time slot 30 will be available for user payload data.

RFL recommends using the Network Communications Module (NCM) for network communications on time slot 31.

Note from the above discussion that an E1 network can have between 28 and 31 time slots available for user payload depending on the system configuration.




2.2.3 DROP/INSERT FUNCTIONALITY

A drop/insert multiplexer is essentially a multiplexer configured as two back-to-back E1 Common Modules (CM4s), in which some circuits terminate while others pass through. A drop/insert multiplexer can terminate payload circuits from either of two different E1 circuits; that is, from either of two different locations. (See Figure 2-2.)

2.2.4 POINT-TO-POINT SYSTEMS

The simplest type of IMUX 2000 M-DACS system configuration is a point-to-point system. A point-to-point system consists of two M-DACS multiplexers connected by a single E1 electrical or fiber optic circuit. (See Figure 2-3.) As the figure illustrates, the same payload circuits will appear at both ends of a point-to-point system. Most payload types (such as voice and full-duplex data circuits) are bi-directional, and will have both an input and an output at each terminal multiplexer.

2.2.5 LINEAR DROP/INSERT SYSTEMS

The addition of one or more drop/insert multiplexers converts a simple point-to-point system into a linear drop/insert system. (See Figure 2-4.) Data, voice, and orderwire (multiple drop voice) circuits can be established between any two locations in a E1 drop/insert system. As shown in Figure 2-4, a three-location system can provide circuits between Locations 1 and 2, Locations 2 and 3, and Locations 1 and 3. The only limiting factor is the capacity of the E1 circuit between any two adjacent locations, which is 32 time slots. Drop/insert systems are not limited to a single drop/insert multiplexer, and may contain more than three locations.

2.2.6 CROSS-CONNECT MODE OF OPERATION

The DACS module has eight bi-directional E1 ports. The DACS module allows any received DS0 from any port to be transmitted as any DS0 on any port. The DS0 grooming takes place by time slot interchanging. Each incoming E1 is disassembled into DS0s. Then each DS0 is temporarily held in memory, until it is needed to be combined into the outgoing E1 stream. The DACS module follows the instructions in a time slot interchange map which determines which incoming DS0s will be aligned with which outgoing DS0s. Each DACS module contains 8 time slot interchange maps (0 through 7), one default (normal map) and seven alternate (backup maps). The DACS module maps are normally programmed at the factory to customer specifications but can be re-programmed by the user. This can be done via the RS-232 Remote Port on the MA-235 via the Network Management Software as described in Section 5. A detailed discussion of DACS module mapping can be found in paragraph 2.2.9. A sample mapping of the DACS module can be seen in Figure 2-5 showing time slot interchanging, pass-thru, and hair pinning modes.

The DACS module contains one normal time slot interchange map (map 0), and seven back-up timeslot interchange maps (maps 1-7). During normal operation, the DACS module monitors the status of all enabled port receivers. If a problem is detected by a port receiver, the DACS module will switch (if switching is enabled) into a backup (or alternate) map. The exact conditions which cause the map switch, as well as the criteria used to select which map to use, are programmable by the user. Refer to paragraph 2.2.9 for more detail on DACS module mapping.

2.2.8 COMPARISON OF CROSS-CONNECT AND LINE-SWITCH MODES.

The DACS module can operate in one of two basic modes, Cross-Connect mode or Line-Switch mode. The basic difference between the two is that Cross-Connect mode utilizes elastic stores and buffers for interim storage of data, while Line Switch mode feeds the received E1 stream directly to a transmitter.

Figure 2-7. DACS module Cross-Connect and Line-Switch mode data paths.

Cross-Connect mode provides great flexibility in handling payload data, and is inherently more stable and immune to E1-level disturbances.

On the other hand, Line Switch mode offers an order of magnitude shorter through-delay, which is particularly important in sensitive teleprotection applications. In a typical network, a E1 path may cross each M-DACS twice and the delays add quickly. The need to remain within delay limits of the equipment can easily trade off against other performance parameters. A comparison of the characteristics of each of the two modes is shown in Table 2-1.

More stable; small incoming disturbances may be absorbed by Cross-Connect mode DACS module.

Less stable; moderate incoming disturbances may affect outgoing E1 streams of Line-Switch mode DACS module.

Usually cleaner switch, less disturbances in the network.

Switch may cause small disturbances to propagate through other Line Switches in the network.

Through-Delay Short (hundreds of microseconds per each pass through the DACS module).

Very short (tens of microseconds per each pass through the DACS module).



2.2.9 DACS MODULE MAPPING

2.2.9.1 INTRODUCTION

The function of the DACS module is to “groom” or break down the DS0 elements in eight E1 frames and then recombine them as specified in a map. Each DACS module has eight DS0 grooming maps labeled map 0, and maps 1-7. Map 0 is the primary DACS module map for no detected failures in the network path.

A typical M-DACS application has two sets of paths: six network paths which are connected either to another T1 system or to a higher order multiplexer, and two paths (Port 5 & 6) connected to the CM-4s. These paths are shown in Figure 2-8. The DACS module monitors E1 data passing through it on its six network paths and uses an alternate map if an error is detected on one of these network paths. The DACS module will switch (if switching is enabled) from map 0 to one of the other alternate maps (1-7) depending on which Map Select Criteria has been met. Map Select Criteria must be programmed by the user using NMS as described in Section 5 of this manual. The DACS module uses programmable and non-programmable criteria for error detection. The DACS module can also detect a recovery from an error and will switch back to the primary map.

To perform these functions, the DACS module uses a microprocessor that monitors its internal circuitry. It is programmable and can be monitored via the M-DACS Serial Control Bus. The DACS module can operate in the following modes: CAS or CCS with CRC4 enabled or not. See paragraph 5.5.3.7.2 for information on how to program these modes using NMS.

2.2.9.2 DS0 GROOMING

The configuration for DS0 grooming is contained in the active map. There are eight maps, one for no network path failure, and seven alternate maps. The transmitted DS0 data is mapped to the received DS0 data. Each transmitted DS0 has a coded index in the map referred to as the DS0 time slot. The content of the DS0 time slot is the address of the received DS0 data. Figure 2-9 shows a typical DACS module routing and its active map. This map is described in detail in paragraph 2.2.9.5.

2.2.9.3 ERROR DETECTION AND SWITCHING

The DACS module constantly monitors its network paths for the following errors: bit error rate exceeded, all ones signal, loss of data and loss of frame and fast loss of frame. Any one of these errors can cause an alarm condition, but only if the enable for each has been selected via programming. In addition, any combination of the four paths can go unused. If unused, a failure in a path will not cause an alarm or a change in operation. Before switching, the DACS module will wait a selected time delay. If the error is removed during this period, the DACS module will not switch.

The bit error rate is determined by periodically sampling the CRC failures and comparing them against a programmed value. The other error conditions are read directly from the internal circuitry of the Dallas transceiver chip. The loss of frame error is either the severely erred framing event (SEFE) or the loss of sync (RLOS) signal. The loss of data signal is receive carrier loss (RCL). The all ones signal is the blue alarm (RBL). The fast loss of frame error is the loss of the fast reframe pattern.

2.2.9.4 ERROR RECOVERY

Although a DACS module has switched, it will still transmit DSOs along the failed network path as directed by the new map. Any transceiver affected by an error will undergo recovery, even if it has not caused a switch.

Since a transceiver can only monitor receive errors, it insures that its fellow transceiver gets an error by sending an all ones signal for 10 ms. After this, the transceiver waits until all errors are cleared. It allows an extra 50 ms period after errors are cleared to allow the fellow transceiver to fully reframe. Then it waits an extra recovery time before going fully on line.

Typical DACS module routing for Map 0

June 19, 2006 2-12 (973) 334-3100


Figure 2-9. A typical DACS module and its active map.



2.2.9.5 DESCRIPTION OF A TYPICAL DACS MODULE MAP Figure 2-9 represents a typical DACS module routing and its active map. Each DACS module has eight bi-directional ports labeled Port 1 through Port 8. Each port has a E1 frame, and each frame has 31 DS0 time slots labeled Time Slot 1 through Time Slot 31. The contents of each time slot, has two numbers separated by a comma. The first number is the Port number, and the second number is the Time Slot number.

The map shows where the DS0 data is coming from and where it is going to. The position in the map, which is the DS0 time slot, and its corresponding port number, is where the data is going to and the content of that DS0 time slot is where the data is coming from. This can be better understood by referring to the following examples.

Example 1: 3,01 under the heading Port 2 is located in time slot 1. This indicates that the data going to Port 2 time slot 1 came from Port 3 time slot 1.



If a time slot is not configured to pass data, it will be labeled 0,FF. Note in Figure 2-9 that each port has two columns, an RX column and a TX column. The RX column cannot be changed by the user. The TX column can be changed by the user.

2.2.9.6 MAPPING OF A DACS RING

Figure 2-10 shows an example of a fiber optic E1 Loop System consisting of four M-DACS units labeled M-DACS A, M-DACS B, M-DACS C, and M-DACS D. In this example no failures are detected in any of the network paths. Therefore, each DACS module in the M-DACS unit is using its own map 0. The outer heavy line represents the primary path and the inner light line represents the backup path.

Figure 2-11 shows the same E1 Loop System with a break in the network path between M-DACS A and M-DACS B. The break can be in any one of the primary path fiber optic cables between M-DACS A and M-DACS B. Let’s assume in this example that the break occurred between M-DACS A port 1 and M-DACS B port 4. This will be detected by M-DACS A and M-DACS B and will cause M-DACS A to switch to map 1 and M-DACS B to switch to map 4. M-DACS C and D will be unaffected and therefore will still use map 0. Theremapping will cause data to be re-routed away from all direct connections between M-DACS A and M-DACSB, and will now follow the backup path as shown by the heavy line in the Figure 2-11.Table 2-2 shows map 0 for M-DACS A, Table 2-3 shows map 1 for M-DACS A.Table 2-4 shows map 0 for M-DACS B, Table 2-5 shows map 4 for M-DACS B.Table 2-6 shows map 0 for M-DACS C.Table 2-7 shows map 0 for M-DACS D.

2.2.9.7 MAP SELECT CRITERIA

When a DACS module detects a port failure, the failed port switches from Map 0 to an alternate map (Map 1 to Map 7). The map switching takes place in accordance with Map Select Criteria, which must be programmed by the user using NMS.

“X” represents a break in any one of the primary path fiber optic cables. Only the maps for M-DACS A and M-DACS B areeffected. The DACS Map Select Criteria which was programmed by the user causes M-DACS A to switch to map 1 and M-DACS B to switch to map 4.

Each line represents 2 fiber optic cables, one for transmit and one for receive.

When a break occurs as shown, M-DACS D stays in map 0since it has no knowledge of thebreak. Refer to M-DACS D,Map 0 (Table 1-6)

When a break occurs as shown, M-DACS C stays in map 0 since it has no knowledge of the break. Refer to M-DACS C, Map 0 (Table 1-5)
