Cabling
The POTS card normally is connected to a 66 Block using a straight-through cable with
two RJ21X plugs. The cable you need depends on the hardware configuration of the
66 Block or other connection point. See
Attach the cable to the 50-pin Telco jack on the back of the DSLAM that is associated
with the slot the POTS card resides in.
Fastening the Cable with Cable Ties
Procedure
To fasten the Telco connector to the chassis using the provided cable ties:
1. Replace the longer captive screw on the cable connector with the #4-40 Phillips
pan-head screw shipped in a plastic bag with the BAC chassis.
2. Locate the connector on the back of the chassis that corresponds with the slot
where you installed the POTS card. Connectors are labeled 1–3 on the 8620
chassis, and 1–18 on the 8820 chassis.
3. Plug the Telco 50-pin cable into the appropriate connector.
4. 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.
