B2CAU/BU, B3CAU/BU, B5CAU/BU up to eight consoles.
There are two types of consoles: the Digital DSS
(DDSS) and the Electronic (HDSS) console. The
DDSS console can be connected to designated digital
telephone circuits, and the HDSS console can only be
connected to designated PEKU circuits. This section
provides instructions on how to install both types of
consoles.
The DDSS console, which can operate with a digital
telephone (preferably an LCD model), can connect only to circuit 8 of a PDKU digital
telephone circuit. Standard twisted single-pair or two-pair jacketed telephone cable
(maximum 305 metres) is used for the connection.
To accommodate the DDSS console connection, the instrument end of the cable should be
terminated in a BS631 Modular Connector connected to a slave LJU. Refer to
Universal Slot PCB Wiring
