Installation
Mount the wire troughs and the termination blocks. There is a
2.
wire trough above and below each termination block.
If necessary, repeat steps 1 and 2 for a second column.
3.
4. Run the 25-pair amphenol cable on the RJ21X interface to the
termination blocks. If more length is needed, an A25D male-
connector, single-ended, 25-pair, non-plenum cable can be
used.
5. As needed, mount D-rings to properly dress the wires.
6. Cut off the amphenol connector on the cross-connect field
side and strip the wires for each of the 25 pairs.
7. Punch down the 25-pair wires to the termination block.
Route the wires through the fanning slots on the
a.
termination block.
Insert the conductors into the designated 110 connecting
b.
blocks already on the termination block.
Use the D-impact tool to seat the conductors (see
c.
Figure 41).
d. Remove any insulation fragments with a spudger.
8. Test the CO lines for proper connection (see "Testing CO
Lines/Trunks" in this chapter).
Label the network interface jacks, CU module jacks,
9.
termination blocks, and D2R cords properly (see "Labeling
CO Lines/Trunks" in this chapter).
10. For each line/trunk, plug one end of a D2R cord into the
designated jack on the termination block and the other end
into the line/trunk jack on the proper CU module.
Note: The modular jacks on the termination block are 8-wire
jacks. The D2R cords are only 6-wire cords, but they will plug
into the 8-wire jacks.
