Connecting lines and trunks

Throughout this procedure, make sure wiring is not reversed and is on the
proper terminals. Allow enough slack in the wiring to allow tracing and to
reconnect wires if they break at the terminal.
1 Extend incoming wiring (such as cables from the central office or wiring
from a recorded announcement machine) to the MDF and terminate them
on separate connecting blocks.
2 Assign and record terminal numbers (TNs) for each line or trunk.
Determine the location of the line or trunk connection and its assigned
TN from the work order or assignment records.
3 Connect each line and trunk to the TN using cross-connecting wire
(typically 24 AWG type-Z wire). Table 112 lists pair-termination tables
for line and trunk cards in NT8D11 (AC and DC vintage) CE/PE
modules and NT8D37 (AA and DC vintage) IPE Modules.
4 Cross-connect incoming wiring and lines and trunks at the
MDF.
