Direct Station Selection (DSS) Console/System
Connection
The DSS console can be connected to a BDKU/BKDS or
PDKU on any circuit. DSS consoles are associated with
digital telephones via system programming. This section
provides instructions on how to install the consoles.
DSS Console Connections
DSS consoles are connected to BDKU/BDKS or PDKU
PCBs using standard twisted single-pair or two-pair jacketed
telephone cable (maximum 1000 feet, 303 meters) is used for
the connection.
To accommodate the DSS console connection, the
instrument end of the cable should be terminated in a
modular station connector block (RJ11). Refer to
MDF PCB Wiring
Notes
DSS console cable runs must not have cable splits (single or double), cable bridges (of any
●
length) or high resistance or faulty cable splices.
See the appropriate Installation chapter for secondary protection information and loop limits.
●
CAUTION!

for wiring/interconnecting details.
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.
