Chapter 1. System Overview and Modes of Operation Line Interface Units Line Interface Units (LIUs) perform the primary multiplexing functions in the D/I Mux III system. Information from the various line cards is combined and converted to T1 format, and information from the network is distributed to the line cards, through the LIUs.
Page 53
Chapter 1. System Overview and Modes of Operation Figure 1-14. Line Interface Unit Block Diagram LIU Network Loop Switch The LIU Network Loop switch sends a standard loopback code to another D/I Mux III or Channel Service Unit (CSU) at the remote end. After a network loop is established, the information sent to the remote end will return to the local D/I Mux III as a loopback.
Chapter 1. System Overview and Modes of Operation T1 Interface Units Coastcom offers five interfaces to the T1 transmission lines for various types of applications. There are three versions of the Dual Channel Service Unit (CSU) Interface (with integral CSU functionality), and two versions of the Dual Digital Service Cross-Connect DSX-1 Interface (with no CSU functionality).
(AIS, an unframed all-ones T1 signal) to the network. If power fails in drop-and-insert mode, the T1 signal bypasses the shelf using only the equalization networks. Power Supplies Coastcom currently offers two (2) different power supplies for use with the D/I Mux III. -48 VDC Redundant (P/N 30338-902) The 30338-902 is a DC-to-DC converter used to power D/I Mux equipment from an external -48 VDC input supply.
Chapter 1. System Overview and Modes of Operation The Dual Synchronous Data Channel Unit (DSDCU) is ideal for computer- aided design (CAD), computer-aided manufacturing (CAM), and high speed batch data applications. This protocol- transparent card also finds applications in multi-site polled or packetized LAN environments, and videoconferencing.
Chapter 1. System Overview and Modes of Operation MODES OF OPERATION There are four modes of operation available with a D/I Mux III system. The three main modes of operation are single channel bank, drop-and-insert, and dual channel bank. These modes relate to the setup, timing, and structure of the T1 network.
Chapter 1. System Overview and Modes of Operation Drop-and-Insert Operation In drop-and-insert operation a D/I Mux III connects two T1 transmission lines in a unique fashion, as depicted in Figure 1-18. The D/I Mux III takes clock and DS0 channels from one T1 transmission port and passes them through the system to the other T1 transmission port.
• DB-9 Clock - The DB-9 Clock is an 8 Kbps to 1.544 Mbps TTL or V.35 external clock brought into the SYNC I/O connector on the back of the D/I Mux III system shelf. • Slot 2 Synchronization - The Slot 2 Sync is an 8 Kbps to 1.544 Mbps clock recovered from a...
Figure 2-1. In this configuration, the D/I Mux III connects T1 to the public digital switching system. Network-compatible circuits are a requirement, and include all of Coastcom's standard voice frequency interfaces and Digital Dataphone Service (DDS) data cards. Each circuit is given a telephone number or circuit identifier.
In the Proprietary mode, the DS0B can support synchronous and asynchronous transmission. Coastcom's single-port SDM line card offers DS0A DDS type data at rates of 2.4, 4.8, and 9.6 Kbps. A single DS0A data circuit takes up all of a 64 Kbps DS0 transmission channel.

(shared). Historically, the common connection between PBXs and local central offices has been 4-Wire Earth and Magnet (E&M) trunks. Coastcom offers 4-Wire E&M line cards for connection of PBXs within a private T1 network. Corporations that conduct a large amount of communication between their various facilities can benefit by dedicating a T1 network to internal communications.
Chapter 2. Applications Drop-and-Insert Drop-and-insert operation is used to transport information to several locations along a single T1 transmission line, as depicted in Figure 2-3. Systems connected to the drop-and-insert network can be used to communicate with several locations. Running one T1 line, instead of several, is highly cost effective in that transmission line costs are minimized, and a drop-and-insert network uses less equipment than does channel bank technology.
Chapter 2. Applications Drop-and-insert operation is ideal for polled data networks. A data line card at a control center sends data on one of the T1 channels to all the data line cards that occupy the same DS0 transmission channel. Only the polled Data Terminal Equipment (DTE) will communicate back to the control center.
Chapter 3. Installation Chapter 3. INSTALLATION This chapter describes the D/I Mux III system shelf and common equipment hardware installation. Installation of the shelves, wiring, common equipment, and the control terminal are given in detail. A brief description of line card installation is included. Refer to individual line card user manuals for more detailed installation instructions for each line card.
Because all modules are inserted into the front of the shelf, enough space must exist in front of the system to allow installation and access to the modules. Coastcom recommends allowing an unobstructed depth of 18 inches at the back of the shelf for wiring access, and an unobstructed space of 30 inches at the front of the shelf for module access.
-48 V DC powered system. -48 V DC Power Supply Capacity Coastcom’s -48 V DC Power Supply (P/N 30338-902), either by itself or with a second 30338-902, can power all combinations of line cards up to the maximum D/I Mux III shelf capacity of 24.
The D/I Mux III is commonly installed in a 19-inch or, with rack adapter brackets, in a 23-inch rack, or cabinet. Accessory equipment also allows the D/I Mux III to be wall- or desktop-mounted. There are two methods for wall mounting a D/I Mux III system. A description of all the installations follows. Rack and Cabinet Installation D/I Mux III shelves mount on standard 19-inch or 23-inch mounting racks.
Figure 3-2. Rack Installation Desktop The D/I Mux III can be mounted on a table or desk top using the Coastcom Table Mount Base (P/N 117667-01). The Table Mount Base is recommended because it allows for proper air circulation under and through the D/I Mux III.
Chapter 3. Installation Figure 3-3. Table Mount Base Wall Mounting The D/I Mux III can be wall mounted when no rack mounting facilities are available. Research applicable building codes to ensure compliance. Mount the shelf where ventilation is best. Cooler operation of the unit will prolong the life of components and circuitry. Avoid wet or extremely humid locations.

Chapter 3. Installation Planning and Installation Off-premises connections: Telecommunication cables that leave the facility (off-premises wiring) can be subject to lightning and / or power surge conditions. Care must be taken that proper surge protection devices for such lines are installed prior to connecting them to a D/I Mux III multiplexer.
Chapter 3. Installation Grounding: Protection against safety fault or surge current is provided by connecting the D/I Mux III chassis to the facility earth ground. Since both safety fault currents and surge events are conducted to earth ground by this connection, it should be made with a short, direct, heavy grounding conductor, # 10 AWG or heavier. If not grounded in this manner, an adequate ground may be obtained through the D/I Mux III mounting ears if the facility equipment rack is securely grounded to the facility earth ground via a heavy, direct conductor.

Chapter 5. Diagnostics Chapter 5. DIAGNOSTICS D/I Mux III system diagnostics include alarms, power-up sequences, test loopbacks, and individual circuit testing. The T1 alarms are the standard T1 Bell System alarms; local, remote, and Carrier Group Alarm (CGA). Optioned with a Dual CSU Interface, the D/I Mux III can initiate a T1 bypass, T1 CSU loopback, and also respond to the network's T1 CSU loopback request.
Bipolar Violations, Bit 7 Zeros Suppression, 0-Density, and All Ones. These alarms are displayed on the Line Interface Unit (LIU) front panel Light Emitting Diodes (LEDs), and in the D/I Mux III system software. If one of these primary T1 alarms activates, an inspection of the T1 cable connections should be conducted, and the T1 carrier company should be called.
Chapter 5. Diagnostics B7 Alarm The Bit 7 Zeros Suppression Alarm (B7) LED illuminates if the D/I Mux III has been programmed for bit seven zero suppression. While historic, this type of zero suppression is rarely used, and should not be used for data circuits. BPV Alarm The Bipolar Violations Alarm (BPV) LED illuminates whenever the LIUs detect a series of bipolar violations.

Chapter 5. Diagnostics Drop-and-Insert Mode Tests Use these procedures when installing the D/I Mux III multiplexer for drop-and-insert operation. D4 channel banks, or D/I Mux IIIs in channel bank mode, are required at both ends of the T1 links to perform these procedures. The alarm function tests require a jackfield. Note: Single channel bank mode testing should be performed prior to drop-and-insert mode testing.

The FRM LED and the LOC LED on LIU A light. After approximately 2.5 seconds, the CGA LED illuminates, generating a remote alarm.
LIUs. Loopback Tests The following sections describe, and depict, the various D/I Mux III system loopbacks. Refer to the software diagnostics portion of this chapter for instructions on how to initiate and remove these loopbacks.
Chapter 5. Diagnostics Channel Bank: Bypass In channel bank bypass mode, the PCM span B input path to LIU B is broken, and replaced with the output from LIU A. From the output of LIU B, an Alarm Indication Signal (AIS) is sent to the output of span A.
Chapter 5. Diagnostics Channel Bank: Line Loopback Line loopback is set in response to receiving the “Line Loop Set” code on a span's input, or via software. Pulse Code Modulation (PCM) arriving at the input is looped back to the opposite span's output.
Chapter 5. Diagnostics Channel Bank: Payload Loopback Payload loopback is initiated from the D/I Mux III software interface. In payload loopback, the LIUs are included in the data path. Incoming PCM from span B is sent to the input of LIU B, then from the output of LIU B to the input of LIU A, and finally from the output of LIU A to the output of span A, as depicted in Figure 5-10.
Chapter 5. Diagnostics Drop-and-Insert: Normal Operation Under normal drop-and-insert operation, the Dual CSU Interface routes incoming PCM from span B to the input of LIU B, and sends PCM from the output of LIU B to the output of span B. Incoming PCM from span A is sent to the input of LIU A, and PCM from the output of LIU A is sent to the output of span A.
Chapter 5. Diagnostics Drop-and-Insert: Bypass Bypass mode removes the D/I Mux III from the T1 line by bypassing the incoming T1 PCM around the LIUs. The Dual CSU Interface receivers and line buildouts are left in line to provide the correct levels on the T1 line. Within the D/I Mux III shelf, the output of LIU B is connected to the input of LIU A, and the output of LIU A is connected to the input of LIU B, as illustrated in Figure 5-12.
Chapter 5. Diagnostics Drop-and-Insert: Line Loopback Line loopback is set in response to receiving the “Line Loop Set” code on a span's input. PCM arriving at the input is looped back to the opposite span's output. The LIUs are not in the PCM path.
Page 206
Chapter 5. Diagnostics Drop-and-Insert: T1-2 Line Loopback Line Loop Set code received on the input of span A causes span A input PCM to be looped back out span B before reaching the LIUs, as well as passing it on to the input of LIU A.
Page 207
Chapter 5. Diagnostics Drop-and-Insert: T1-1 and T1-2 Line Loopback Line Loop Set code received on span B input causes PCM to be looped back out span A's output, as well as being passed on to the input of LIU B. The PCM from the output of the LIU A is blocked.
Chapter 5. Diagnostics Drop-and-Insert: Payload Loopback Payload loopback is initiated from the D/I Mux III software interface. In payload loopback, the LIUs are included in the data path; line loopback does not include the LIUs. In payload loopback, the loopback occurs after rather than before the LIUs. Drop-and-Insert: T1-1 Payload Loopback Incoming PCM from span B is sent to the input of LIU B, then from the output of LIU B to the input of LIU A, and finally from the output of LIU A to the output of span A.

Chapter 5. Diagnostics Drop-and-Insert: T1-2 Payload Loopback Incoming PCM from span A is sent to the input of LIU A, then from the output of LIU A to the input of LIU B, and finally from the output of LIU B to the output of span B. PCM from the output of LIU A is also sent to the output of span A.
Chapter 5. Diagnostics Dual Channel Bank: Normal Operation In Dual Channel Bank operation, the D/I Mux III acts as two separate channel banks, one looking to T1-1, and the other looking to T1-2. The Dual CSU Interface routes incoming PCM from span B to the input of LIU B, and sends PCM from the output of LIU B to the output of span B.
Chapter 5. Diagnostics Dual Channel Bank: Line Loopback Line loopback is set in response to receiving a Line Loop Set code on a span's input. PCM arriving at the input is looped back to the opposite span's output. The LIUs are not in the PCM path.
Page 212
Chapter 5. Diagnostics Dual Channel Bank: T1-2 Line Loopback Line Loop Set code received on the input of span A causes PCM to be looped back out the output of span B. Output PCM from LIU A is sent to the output of span A. PCM from the input of span B and the output of LIU B are blocked.
Page 213
Chapter 5. Diagnostics Dual Channel Bank: T1-1 and T1-2 Line Loopback Line Loop Set code received on span B input causes PCM to be looped back out span A's output before reaching the LIUs, as well as being passed on to the input of LIU B. The PCM from the output of LIU B is blocked.
Chapter 5. Diagnostics Dual Channel Bank: Payload Loopback Payload loopback is initiated from the D/I Mux III software interface. In payload loopback, the LIUs are included in the data path; line loopback does not include the LIUs. In payload loopback, the loopback occurs after rather than before the LIUs.
Page 215
Chapter 5. Diagnostics Dual Channel Bank: T1-2 Payload Loopback PCM from span A (T1-2) is sent to the input of LIU A. The output of LIU A is looped to the input of LIU B. The output of LIU B is sent out on span B (T1-2). The input from span B (T1-1) is blocked, as is the output path to span A (T1-1).

D/I Mux III User’s Manual Appendix G. Modem Interfaces Modem Considerations There are a number of considerations to be taken into account when planning modem installation. Among the problems that might be encountered are line noise, timing discrepancies, sequencing difficulty, and control signalling errors. Each is described below. Line Noise Noise on the telephone line can inject data errors, can cause loss of carrier, and can and terminate the connection.
The basic sequence for modem call processing is listed below. More specific steps are listed in the following section for connecting and terminating modems when using the D/I Mux III system, the Digital Cross Connect II (DXC II) system, and the Network Communications Controller (NCC) system.
Processing Messages Proceed with message transmissions. Alarm mode switching during message processing is controlled by Coastcom’s NCC5 and NCC6 programs when communicating with the D/I Mux III system (the NCC2 program does not switch alarm modes). The program sends a Machine Machine Language (MML) command to disable alarm reporting, thus allowing ASCII or MML data transmission/reception to occur.
D/I Mux III User’s Manual Appendix G. Modem Interfaces Terminating Connection At the conclusion of transmission, the connection must be terminated. Follow the steps listed below for terminating connection with each device listed. Port Expander If a port expander, or other black box device, has been configured into the network follow the steps listed below, otherwise proceed to the next section.
Wait for an OK response (which should appear within 3 seconds), and continue. Port Coastcom’s NCC5 program will release the serial port back to the system. The NCC2 and NCC6 programs will release the port by restoring the original serial interrupt vector.
