Install 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.
Off-Premises or Out-of-Building Stations
Out-of-building campus stations are telephones not physically located in the same building as
the equipment room but located on the same property. Only analog telephones connected to
TN746B, TN769, or TN2183 Analog Line circuit packs can be installed out-of-building.
