Connecting a Line Card Using Cable Ties
Procedure
To connect a line card in the 8820 BAC using the provided cable ties:
1. On each cable, replace the longer captive screw on the cable connector with
the #4-40 Phillips pan-head screw shipped in a plastic bag with the unit. Do
not insert the screw past the connector body until
Step 4 .
2. Plug the Telco 50-pin cable into the appropriate connector for the slot
containing the card (labeled 1–18) on the rear of the 8820 chassis.
3. Thread the provided cable tie through the anchor mount on the end of the
connector where the cable will lie. Tighten the cable tie around the connector
and cut off any excess.
4. Secure the other end of the Telco 50-pin cable by tightening the Phillips
pan-head screw (that you replaced in Step 1 ) on the right side of the
connector.
5. Make sure the other end of the cable is connected to the appropriate POTS
splitter shelf, MDF, or demarcation point.

the other end. The connector’s captive screw must be replaced with a shorter one
and the locking pivot bracket must be installed on the other end, as shown in the
following procedure.
