5.2 Monitoring

an OC-12c/STM-4c

Interface

This section describes the physical indicators for an analysis device configured to
support OC-12c/STM-4c. You can obtain a different view of this same
information through the Channel tab, described on page 68. The ATM tab is
described on page 72.

Physical Tab

The Physical tab looks like this for an OC-12c/STM-4c interface:

Card number and interface type.

The sections below describe the alarms and errors specific to OC-12c/STM-4c.
