Figure 2-17. 258A and BR2580A Adapters
The 356A adapter plugs into a 25-pair female cable connector. See Figure 2-18
.
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.
