Connecting Blocks
Working With 8-Pin Jacks
The system uses 8-pin mod jacks to connect extensions, trunks and optional equipment. Using the Installation
Cable (P/N 80892) makes it easy to connect the PCBs to standard 66M1-50 connecting blocks. These cables
have six 8-pin modular jacks on one end and are unterminated on the other. In general, each cabinet needs:
● One 66M1-50 block and Installation Cable (P/N 80892) for extensions and optional equipment.
● One 66M1-50 block and Installation Cable (P/N 80892) for trunks.
● Depending on your PCB configuration and local codes, you may need an additional 66M1-50 block
and Installation Cable (P/N 80892) for optional equipment.
Punching Down the Cables
The Installation Cables have six 8-pin jacks installed on one end and are unterminated on the other. Each
8-pin jack connects 4 extensions or 4 trunks.
To punch down the cables (Figure 2-12) through (Figure 2-15):
1. For each 66M1-50 block, punch down the Installation Cable in standard color-code order.
- Use Figure 2-12 Connecting Extensions on page 2-10 when connecting extensions.
- Use Figure 2-13 Connecting Trunks on page 2-11 when connecting trunks.
2. After you have punched down your cables, route them through the side of the cabinet and secure them
with the strain relief (Figure 2-14 Securing the Cables on page 2-12).
Making Your Own Cables
If you want to make your cables (instead of using Installation Cable P/N 80892), follow the pinouts in
Figure 2-15 8-Pin (RJ61X) Jack Pinouts on page 2-13.
