Wire Pair Identification
The feeder (in) and distribution (out) pairs are identified separately on the face of the enclosure blocks by color
code. The binding posts or IDC clips are given terminal pair identification, starting with one and proceeding to
the last pair number for that particular type of pair. Therefore, each has a feeder (in-green) pair number one
and a distribution (out-blue) pair number one, etc. Terminal blocks are numbered horizontally (EXAMPLE: Row
1, pairs 1-5; row 2, pairs 6-10; on RLS: Row 1, pairs 1-10; etc.).
Feeder Pairs
All standard pole-mounted cross-connect enclosures of 600 pairs and larger are configured for a feeder to
distribution ratio of 1 to 2. Engineering design may dictate different counts. Feeder pairs are located in the left
column for 100-pair to 400-pair enclosures; in the center column for 600-pair to 900-pair enclosures and in the
two center columns for 1200-pair to 2700-pair enclosures. Refer to
