Direct Station Selection (DSS) Console/System Connection

Direct Station Selection (DSS) Console/System
Connection
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.
DDSS Console
Connections
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 CW1308 twisted single-pair or two-pair jacketed
telephone cable (maximum 303 meters) is used for the connection.
To accommodate the DDSS console line cord, the cable should be terminated in a BS6312
modular connector which then plugs into a slave LJU at the station location. The standard
single-pair, modular DDSS console line cord that is sent with the telephone is 3 metres in
length, the maximum allowed is 10 metres and has a BS6312 type connector at the LJU end
of the lead. Refer to
interconnecting details.
Notes
DDSS console cable runs must not have cable splits (single or double), cable bridges (of
any length) or high resistance or faulty cable splices.
CAUTION!

DDSS Programming

Program 03: Code 64 identifies the slots that support DDSS consoles.
Program 28: Assigns DDSS console(s) to telephones.

Chapter 4 – DK40 Universal Slot PCB Wiring
When installing the DDSS cable, do not run the cables parallel if they
are within 915 mm of an AC power line. AC power lines should be
crossed at right (90°) angles only. In particular, avoid running station
wire pairs near devices that generate electrical noise, such as neon or
fluorescent light fixtures.
