The cabling for off-premises stations is provided by the local telephone company. These 
stations can appear on any of the RJ21X network interfaces provided for the CO trunks. 

CAUTION:

Use only an FCC-approved (or equivalent) analog type telephone (such as a 
2500-type) as an off-premises station. The TN746B and TN2183 Analog Line 
circuit packs can be connected to off-premises stations.

To wire off-premises stations:

1. Install an A25D cable between the RJ21X network interface and a sneak fuse panel. 

2. At the MDF, connect jumper wires between 1 row/connecting block in the green field and up 

to 3 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 Step 2.

4. Install a green label on the terminal block to identify the remote location. 

5. Administer per Administrator’s Guide for Avaya Communication Manager.

Out-of-building campus stations are those telephones not physically located in the same 
building as the equipment room but are located on the same property.

TN746B, TN2183, or TN769 Analog Line circuit packs can be installed out-of-building.

The maximum distance from the system cabinet to the out-of-building voice terminal is 6000
