Syntax of the "no" form
The no form of this command returns the value to the default setting:

Controller configuration:
Example
The following example sets the short haul LBO to 266 feet:
XSR(config)#controller t1 1/0
XSR(config-controller<T1-1/0>)#cablelength short 266
channel-group
For T1/E1 controllers only
This command specifies timeslots that map to channel‐groups for T1/E1/ISDN‐PRI data lines (for
channelized/fractional T1/E1/ISDN‐PRI services).
Timeslots and fractional/channelized T1/E1 groups allow multiple logical WAN interfaces to be
created out of a single channelized T1 or E1 controller port. The logical interfaces created can have
different encapsulation types – PPP, Frame Relay, etc. For each channel group (a fraction of a T1/
E1/ISDN‐PRI line), the following values must be set:
1.
The channel group must be identified by a channel group number.
2.
One or more timeslots of the T1/E1/ISDN‐PRI line must be assigned to a particular channel
group.
3.
The base speed increment for the single channel can be specified in kilobits per second.
