T1/E1 & T3/E3 Commands
XSR CLI Reference Guide 2-59
Syntax of the “no” Form
Use the no form of the command to remove a channel group:
no channel-group number
Defaults
Speed: 64 kbps for both T1 and E1 controllers.
Mode
Controller configuration:
XSR(config-controller<xx>)#
Example
The following example issues the
channel-group
command for T1 controller configuration. Two
channels are created – the first creates group number 0 with timeslots 1 to 10; the second creates
group number 1 with timeslots 11 to 20, both with default speeds of 64 kbps.
XSR(config)#controller t1 1/0

clock source
This command defines the clock source for a T1/E1 or T3/E3 line. It is needed because of
synchronous transmission of data on digital interfaces as in the case of T1/E1 or T3/E3 lines. The
clock source sets the required timing synchronization between the transmitter and receiver using
line and internal settings.
Syntax
clock source {line | internal}
Syntax of the “no” Form
The no form of this command returns the value to the default setting:
no clock source
range
Assigns one or more timeslots or a range of timeslots to a channel group, ranging
from 1 to 24 for T1 and 1 to 31 for E1.
speed
Line speed of the T1/E1 link in kilobits per second.
line
Clock derived from the T1/E1 or T3/E3 line provider.
internal
Clock from a chip on the T1/E1 or T3/E3 controller card.
