APS on channelized CES MDAs

Overview

You can protect a channelized SONET/SDH port on a channelized CES MDA with a protection port of the same speed on a different channelized CES MDA in the same NE. The APS configuration on a channelized CES MDA provides protection against a port, MDA, or IOM failure. All SONET/SDH paths and TDM channels in a SONET/SDH port are protected.

Consider the following when you configure APS protection on a deep channel on a channelized CES MDA:

• Both SONET and SDH channels are supported.

• Up to three common configuration SONET channels can be created in an APS configuration.
