BEFORE YOU START CABLING
Reviewing the Installation Method
Your system uses a different installation method for extensions
and trunk/AUX connections:
Extension Blocks
The system uses a 66M1-50 extension block and a second
66M1-50 cross connect block for connecting extensions.
See The Extension Blockon page 2-4 and the illustration on
page 2-5.
Trunk/AUX Mod Jacks
You’ll use up to 6 mod jacks for the trunk/AUX connections.
Turn to Trunk and AUX Mod Jackson page 2-8 for more on
this method.
Your telco normally provides trunks in RJ-11C, RJ-14C, or
RJ-25C modular jacks.
For more on connecting Door Boxes, Paging, music and power
failure, turn to Section 4, Optional Equipment.

1. Arrange your extension and extension cross-connect blocks
according to the illustration below.
2. Following Figure 2-2 on page 2-6, punch down a standard
25-pair cable on the extension block.
