Station Circuit Distribution from Equipment Room

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.

4-Pair Station Circuits

Four-pair circuits can be run directly from an equipment room MDF to a 258A or BR2580A
adapter as shown in
station cables connect the adapter to the information outlets.
The 4-pair station cables can be run directly from the equipment room to the information outlets
if 4-pair terminal blocks are used in the distribution field. See

terminal blocks.
If 110-type terminal blocks are used with a modular plug-ended station cable, an adapter can be
connected directly to the 110-type terminal block connectors. See
