Single Line Telephones
Description
The system is compatible with 500 type (dial pulse) and 2500 type (DTMF) analog telephone devices. This
includes on-premises single line telephones (SLTs), fax machines, and modems.
In DSX-40, SLTs connect to analog ports in the main equipment cabinet. In DSX-80/160, SLTs connect to
SLIU PCBs. Each analog port provides power and ring voltage for the connected SLT. The analog ports use
DTMF receivers. Each system provides 10 DTMF receivers that are shared by all connected analog ports.
Message Waiting
Both DSX-40 and DSX-80/160 support FSK Message Waiting lamps. DSX-80/160 also provides support for
high voltage Message Waiting lamps – while DSX-40 does not.
