4-Pair Station Circuits; 3-Pair To 4-Pair Station Circuit Distribution - Avaya S8500 Manual

Connecting the main distribution frame to stations and the public switched telephone network

4-pair station circuits

Four-pair circuits, via station cables, can be run directly from an equipment room MDF to a 258A or
BR2580A adapter as shown in
pair 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
location, on page 196. The station cables must be field-terminated on the 110-type 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

from an equipment room MDF to a satellite location using 110-type hardware. Four-pair circuits are
distributed from the satellite location to the information outlets.
Three-pair circuits can also be run directly from the equipment room MDF to a 356A adapter as shown in
Figure 74, 3-pair to 4-pair circuit distribution and connectivity,
connect the adapter to the information outlets. Four-pair station cables can be run directly from a satellite
location to the information outlets as previously described.
