•
If you specify internal clocking, the interface transmits data using the line module or
the chassis as the internal clock. You must specify one of the following for internal
clocking:
•
module —Specifies internal clock is from the line module itself
•
chassis —Specifies internal clock is from the configured router clock
•
If you specify line clocking, the interface transmits data with a clock recovered from
the line’s receive data stream.
•
Example
host1(config-controll)# t1 2,4-10 clock source line
•
Use the no version to restore the default value, line .
•
See t1 clock source.
t1 description
•
Use to assign a text description or an alias to T1 or fractional T1 channels on a CT3
module.
•
You can use this command to help you identify the interface and keep track of interface
connections.
•
The description or alias can be a maximum of 80 characters.
•
Use “show controllers t3” on page 29 to display the text description.
•
Examples
host1(config-controll)# t1 2 description london t1 interface
host1(config-controll)# t1 2/1 description london first ft1 interface

t1 framing

The framing format you choose must be compatible with the framing format at the
other end of the line.
