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
Chapter 6 – MDF PCB Wiring
for wiring/interconnecting details.
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!
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.
