Installing off-premises station wiring
The local telephone company provides cabling outside the building for off-premises stations. The off-
premises stations can appear on any of the RJ21X network interfaces provided for the central office (CO)
trunks.
CAUTION:
Only an FCC-approved (or equivalent) analog type telephone (such as a 2500-type), can
be used as an off-premises station. The TN746B and TN2183 Analog Line circuit packs
can be connected to off-premises stations.
1 Install an A25D (male to male) cable between the RJ21X network interface and a sneak fuse
panel.
2 At the main distribution frame (MDF), connect jumper wires between one row/connecting block
in the green field and up to three rows/connecting blocks in the purple field to concentrate the
analog line pairs.
3 Connect an A25D cable between the sneak fuse panel and the terminal block connector associated
with the green row in the previous step.
4 Install a green label on the terminal block to identify the remote location.
5 Administer per the Administrator’s Guide for Avaya Communication Manager.
