Location of Telephone Line Connections
Wireline Connector
When 4-wire (2 line) telephone connections are required, Line 1 and Line 2 are
provided through the 4–position wire wrap terminal connector. Table 10 provides
a description of the Wireline connector line pair assignments.
Connector 4 has 8 holes:
- the round holes are for wire insertion, and
- the square holes are for insert release.
This wire-trap terminal connector accepts only 0.52 sq mm (20 AWG) to 0.2
sq mm (24 AWG); solid wire
or stranded wire with a tin topcoat. Wires inserted
into the connector should be stripped to length 9.53mm (0.375 in).
As a removal release tool, use either:
- a stripped wire of any of above sizes, or
- the Wireline connector tool, part number 6600809D00.
Before applying excessive pullout force on the telephone connection wires, be
sure to release wires properly.
System Connector
When 8-wire (4 line) telephone connections are required:
- Line 1 and Line 2 are provided through the 4-terminal Telephone connector.
- Line 3 and Line 4 are provided through the System connector.
The location of the Telephone and System connectors on the station rear panel is
shown in Figure 9.
Table 4 describes the System connector pin assignments for Line Pairs 3 and 4.
