Single Line Interface Board
The single line interface board (SLIBE and SLIBC) provide the interface to twelve 2500-type
telephones. The SLIB signals interface with industry-standard ringers and message waiting
lights.
An industry standard RJ21-type female connector is mounted on the front edge of the PCB
for connection to the station interfaces. In addition, one LED is mounted on the PCB to
indicate the in use state of the connected telephones. It will turn on when one or more ports
are busy.
The SLIBE can support a DTRU4 board (4 DTMF receivers). The SLIBC has built-in DTMF
receiver capability for all SLIBC circuits (this DTMF receiver capability cannot be used as a
shared system resource; the capability only applies to SLIBC circuits). The SLIBE and SLIBC can
support two MSGU boards in a daughter board type arrangement.
