Configuring Ports
A:7710-3>
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..24). For an E1 channel-group, up to 31
timeslots can be assigned (numbered 2..32). For ATM, all timeslots are auto-configured when a
channel group gets created (there is no sub-E1 for ATM). ATM, Frame Relay and BCP-NULL
encapsulation examples follow:
