Connector Interface Modules
Rear connector modules or connecter interface modules (CIMs)
provide connections to the network and various types of customer-
provided equipment (CPE).
They also provide the following connections:
• Alarm relay
These contacts can be wired to an external alarm equipment.
The connector pins provide output as a normally open (NO)
contact, a normally closed (NC) contact, and a common (COM)
lead contact.
Loss of carrier conditions activate the relay contacts. For more
information on alarms, see Chapter 4, Troubleshooting.
• External timing source input
The 8-pin mini-DIN connector receives clock from an external
timing device.
