32 ◆ Installation DSX-80/160 Hardware Manual
Connecting 16ESIU Cards
The 16ESIU Card, just like the COI and SLI Cards, uses 8-pin mod jacks to connect extensions. Using the
Installation Cable (P/N 808920) makes it easy to connect the cards to standard 66M1-50 connecting blocks.
These cables have six 8-pin modular jacks on one end and are unterminated on the other. Each jack connects
four extensions. At minimum, the installation site needs:
❥ One 66M1-50 block and Installation Cable (P/N 808920) for extensions and optional equipment.
❥ One 66M1-50 block and Installation Cable (P/N 808920) for analog lines.
❥ Depending on your card configuration and local codes, you may need an additional 66M1-50 block and
Installation Cable (P/N 808920) for optional equipment.
To punch down the cables:
1. For each 66M1-50 block, punch down the Installation Cable in standard color-code order.
