Direct Station Selection (DSS) Console/System
Connection
The Strata DK40i can support up to three DSS consoles and the DK424 systems configured with
RCTUA can support up to three DSS consoles, RCTUB up to four DSS consoles, RCTUC/D and
RCTUE/F 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
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 twisted single-pair or two-pair jacketed
telephone cable (maximum 1000 feet, 303 meters) is used for the connection.
To accommodate the DDSS console connection, the instrument end of the cable should be
terminated in a modular station connector block (RJ-11). Refer to Chapter 8 – DK40i/DK424
Universal PCB Wiring for wiring/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.
See Chapter 3 – DK40i Installation
See Chapter 5 – DK424 for secondary protection information and loop limits.

DDSS Console Configuration

An RDSU will not support a DDSS.
9-20
and 9-13 and follow these steps:
When installing the DDSS cable, do not run the cables parallel if they are
within three feet 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.
