About The ST1D/ST2D Voice Switches*
Each ST1D/ST2D Voice Switch connects internal extensions or IP phones to a central office
(CO) digital trunk line.
The switch provides connectivity through:
•
One audio input port (3.5 mm stereo) for connecting to a music-on-hold source
•
One audio output port (3.5 mm stereo) for connecting to a corporate paging system
or night bell. You can use a paging adapter to provide a balanced output as well as a
contact closure ideal for overhead paging systems. Refer to the Paging Adapter (PA-1)
Quick Install Guide for information about the Paging Adapter.
•
Two RJ-45 10/100/1000 Mbps LAN connectors
•
One DB-9 (female), RS-232C maintenance port (default 115,200 bps, 8 bits, no parity, 1
stop bit, no handshake) for serial communications
•
USB port for logging/troubleshooting
•
RJ-48C Telco port(s) for connecting the switch to telephone company lines. The ST1D
has one RJ-48C Telco port, and the ST2D has two RJ-48C Telco ports. These are the
T1/E1 configurable connections.
