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.

To install the off-premises station wiring:

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.
