Description

This command defines the channel timeslots for a fractional T1 or E1 line. Your service provider determines the timeslots for your lines.

channel-number

A number identifying the communication channel you are defining. For T1 lines, the channel number can be from 0 to 23; for E1 lines, 0 to 30.

timeslots range

A list of timeslots that make up this communication channel. The list can be a series of comma-separated timeslot numbers, or a pair of timeslots separated by a dash to indicate a range. Timeslot numbers range from 1 to 24 on a T1 line; 1 to 31 for E1. A timeslot cannot belong to more than one channel group.

speed kbps

The speed of a single timeslot in Kbps. Allowable values are 48, 56, and 64. 56 is the default for T1; 64 is the default for E1.

Example

When defining the timeslots range, the value can be a single number or a group of ranges separated by commas and hyphens. For example, the following ranges are all valid:

channel-group 3 timeslots 4
channel-group 5 timeslots 4,6-15,24
channel-group 8 timeslots 4-10
