1. Overview

The UA board allows sets and UA terminals to be connected.

There are two versions of the UA board :

- UA32 allows 32 UA lines to be connected,

- UA16 allows 16 UA lines to be connected. This board is a simpler version of the UA32 board.

UA32 or UA16 board configuration is described in module UA (UA16, UA32) board - Configuration .

UA32 or UA16 board connection is described in module UA (UA16, UA32) board - Connection .

2. Location

The UA interface is connected, via the backpanel, to the system and distribution frame.

3.1. UA module (QUA256)

This daughter board interfaces the UA links and board IPCMs. Two QUA256 are connected on a IPCMlink and each QUA256 processes four UA lines (8 QUA256 on the board). It comprises:

- 4 line interfaces,

- one PCM UA (IMU).

3.1.1. UA line interface

This interface carries out:

- conversion of the (0V/5V) signal into a (-2.5 V/2.5 V) signal sent on the UA line,

- protection of the PCM UA interface against over voltage and overload,

- passband filtering on IMU component input,

- UA line power supply in -48 V via a current limiter. This limiter inhibits UA line power supplywhen the board is removed from the frame and protects the line and power supply against shortcircuits and over voltages.

The UA line is made up of a twisted pair.

3.1.2. PCM UA interface (IMU)

This transmitter/receiver interfaces the system end IPCM link (2.048 Mbits, full duplex) and the terminalend four UA links (628 Kbits, ping-pong mode). This component is transparent for UA frame content.

The UA link presents a 125 µs frame with the following format.

The B1, B2 and B3 channels carry voice and data from the UA terminal or S0 bus connected to the set.

The SIG channel carries UA set signalling and, where appropriate, the D channel of the S0 bus connec-ted to the UA terminal.

Transmission of 4 x 64 Kbit/s channels (B1, B2, SIG, B3) is followed by reception of 4 x 64 Kbit/schannels. The two phases are separated by a hold and propagation time, each starting with a syn-chronization bit (SYN).

Two register blocks (transmission and reception) synchronize the data between the four UA links andthe IPCM link. The data of the IPCM frame are temporarily stored before being sent to the four UAlinks and vice versa.

3.2. Common part

The common part interfaces the UA board with the other system boards. For further details, refer tothe description of the common part.

The four IPCMs present the same configuration.

B BBBBBBB BSS S

IPCM 1, IPCM 2 and IPCM 3 present the same type of frame.

Each IPCM is connected to two QUA256. Therefore, they carry the four TSs (B1, B2, SIG, B3) of eachof the EIGHT UA links.

In addition to the system interfacing function, the 80C188 processor handles UA link level 2.

3.3. Power supply

Board power supply

From the -48 V powering the board, one CM8 converter supplies the +5 V and +12 V voltages requi-red for board operation.

UA lines power supply

The board powers the UA lines with -48 V via the line interfaces. When the board is inserted, the micro-processor controls the current limiters, using CDELIM (1..16), so that line powering starts sequentially,since start up current must be minimized in the system.

A fuse is located on board input on the -48 V powering all the limitation circuits.

- by cable : in this case, distribution frame is carried out with a Type 1 cable with or withoutdistribution module (see module TY1 64PTSDIN cable - Hardware description or module TY164PTSDIN cable with module - Hardware description ),

- by patch panel (VH cabinet only) : in this case, the connection is carried out directly using thepatch panel : 2-wire 32-port module (see module VH rack - Connection - 32 ports module ).
