T1/E1 & T3/E3 Commands
2-58 Configuring T1/E1 and T3/E3 Subsystems
Syntax
cablelength short {133 | 266 | 399 | 533 | 655}
Syntax of the “no” form
The no form of this command returns the value to the default setting:
no cablelength short
Defaults
133 feet
Mode
Controller configuration: XSR(config-controller<xx>)#
Example
The following example sets the short haul LBO to 266 feet:
XSR(config)#controller t1 1/0
XSR(config-controller)#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.
Syntax
channel-group number timeslots range [speed {56 | 64}]
133 0 to 133 feet (cable length for short haul pulse shaping).
266 134 to 266 feet (cable length for short haul pulse shaping).
399 267 to 399 feet (cable length for short haul pulse shaping).
533 400 to 533 feet (cable length for short haul pulse shaping).
655 534 to 655 feet (cable length for short haul pulse shaping).
number Channel‐group number, ranging from 0 to 23 for T1 and 0 to 30 for E1 data lines.
