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:
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.
