This section provides examples to configure PPP, FR, cHDLC, and ATM n*DS0 channels on a channelized port on channelized ASAP OC-3 SFP MDA in slot 1/1/1. The ASAP OC-12 SFP MDA also supports the SONET options.
ALA-A>config# port 1/1/1
At this level you must choose the tributary. When provisioning DS3 nodes on a channelized ASAP OC-3 MDA, you must provision the parent STS1-1 SONET path first.

To set the channelized mode on a port, the DS3 parameter must be in a shutdown state. Clear channel uses out-of-band signaling, not in-band signaling, so the channel's entire bit rate is available. Channelized ports use in-band signaling and must be explicitly enabled.

In the TDM E1 context, configure DS0 channel groups and their parameters. For a DS1 channel-group, up to 24 timeslots can be assigned (numbered 1 to 24). For an E1 channel-group, up to 31 timeslots can be assigned (numbered 2 to 32). For ATM, all timeslots are auto-configured when a channel group is created (there is no sub-E1 for ATM). ATM, Frame Relay and BCP-NULL encapsulation examples follow:

Services can now be applied to the configured channelized ports. Follow examples of other channelized ports in this document.
