Return to Task List
The cabling outside the building for off-premises stations is provided by the local telephone company.
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, for example, a 2500-type,
can be used as an off-premises station. The TN746B and TN2183 Analog Line circuit
packs can be used for off-premises stations.
1 Connect an A25D cable between the RJ21X network interface and a sneak fuse panel. See Install
Sneak Fuse Panels on page 443 for details.
