Connecting to the ATM or IP Network
The connection to the ATM or IP network is made through the Shelf Concentration
and Processing (SCP) card in the BLC. Depending on the model, the SCP card
supports an OC3/STM1, E1 IMA, DS1 IMA, or Gigabit Ethernet uplink. See the
Shelf Concentration and Processing (SCP) Card Installation Instructions for more
information.
Connecting 24-Port Models to an MDF or POTS Splitter
You can connect 24-port ATM line cards to an MDF or other demarcation point
through the BLC. Do not connect the Model 8985 to a POTS splitter. Refer to the
appropriate BLC Installation Guide for more information.
Refer to Connector Pin Assignments in the ATM Line Cards, Models 8955, 8965,
8968, 8975, and 8985, User’s Guide for pinouts of the BLC ports.
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 BLC.
2. Locate the connector on the back of the chassis that corresponds with the slot
where you installed the line card. Connectors are labeled 2 and 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
