CHAPTER 4. STATION WIRING
Adjunct Powering From Site Locations
Adjunct power can be provided through an adapter located in a site
closet. Adjunct power is required when the length of the 4-pair station
wiring from the equipment room or satellite location is more than 250
feet or when the 3-pair station wiring is run from the cross-connect field
to a 356A adapter.
Figure 4-9 shows connections for the 258A and 356A adapters. The
400B2 adapter and D6AP power cord provide power on the fourth pair
of the 4-pair station cable. The D6AP power cord connects to an
individual or a bulk power supply. The D6AP power cord is available in
7-, 14-, and 25-foot lengths.
