Standard 06.01
Cabling lines and trunks
Follow Procedure 39 to connect lines and trunks. Ensure that 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.
Procedure 39
Connecting lines and trunks
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 (TN) 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 33 on
pair-termination tables for line and trunk cards in NT8D37 IPE Modules.

Cross-connect incoming wiring and lines and trunks at the MDF.
