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.
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
Use the no version to remove the text description or alias.
See t1 description.
Use to configure the framing format for T1 channels.
You must specify either esf (extended superframe) or sf (superframe) framing.
The framing format you choose must be compatible with the framing format at the
other end of the line.
Example
host1(config-controll)#t1 2 framing sf
Use the no version to restore the default value, esf.
See t1 framing.
