Single Line Interface Board
The single line interface board (SLIB) provides the interface to six 2500-type telephones. The
SLIBE and SLIBC provide the interface to twelve 2500-type telephones. The SLIB signals
interface with industry-standard ringers and message waiting lights.
Three RJ11 connectors are mounted on the SLIB and 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 SLIB can support a DTRU board (2 DTMF receivers) and a MSGU board in a daughter
board type arrangement. The SLIBE and SLIBC can support a DTRU4 board (4 DTMF receivers)
and two MSGU boards in a daughter board type arrangement.
