Four types of connections are required:

Connecting to an ATM Optical Interface

Connecting the Control Terminal

Connecting to the Ethernet Port

Connecting to the Power Source

Connecting to an To connect a CoreBuilder 7000 family ATM switch port to another ATM Optical Interface CoreBuilder unit, to a LinkSwitch 2700 ATMLink adapter, or to any device

with an ATM optical interface:

1Prepare an optical cable (Tx Rx). You may want to mark the ends of the cable so you can identify them.

2Snap the cable into a CoreBuilder 7000 family ATM switch port in one of the interface modules.

3Snap the other end of the cable into the selected optical interface of the other ATM device. Make sure that each wire connects to Rx on one end and Tx on the other.

4Repeat steps 1-3 for all ATM port connections to the CoreBuilder.

Perform steps 1-4 above when connecting a DS-3 coax cable set (Rx and Tx).
