Site Locations

Site locations are closets that provide a point in the station wiring for the administration of
remote powering. Adapters are used at site locations to terminate the 25-pair station cables and
provide connection points (modular jacks) for power adapters and 4-pair station cables.
The 258A and BR2580A adapters plug into a 25-pair female cable connector. These adapters
divide the 25-pair cable into six 4-pair (modular jack) circuits. See
Adapters'' on page 159.
The 356A adapter plugs into a 25-pair female cable connector. See
159. The 356A adapter divides the 25-pair cable into eight 3-pair circuits. Although the circuits
are 3-pair, the adapters modular jacks will accept the 8-wide modular plug used on the 4-pair
station cable.
!
CAUTION:
Adapters wired similarly to the 356A should not be used. Their jacks do not accept 4-pair
plugs.

Station Circuit Distribution from Equipment Room

This section explains the station circuit distribution from the equipment room to the information
outlets for new wiring installations. Example connection diagrams are provided to show the
options for running and connecting the station cables.
If most of the telephones/voice terminals that require remote powering are within 250 ft
(76.2 m) of the equipment room, 4-pair station circuits are run from the equipment room to the
information outlets. If this is not the case, or if the customer requires 2-point administration,
3-pair station circuits are run from the equipment room to satellite locations. Then, the 4-pair
station circuits are run from the satellite locations to the information outlets.
