CT3 interface view
Parameter
line-number: T1 line number in the range of 1 to 28.
Description
Using the t1 shutdown command, you can shut down a T1 line on the CT3
interface. Using the undo t1 shutdown command, you can enable the T1 line.
By default, T1 line is enabled.
This command will affect not only the specified T1 line but also the serial
interfaces formed by bundling the timeslots of the T1 line. Executing the t1
shutdown command on the specified T1 line will shut down all these serial
interfaces and the data transmission and receiving will be stopped as a result.
Likewise, executing the undo t1 shutdown command will re-enable all these serial
interfaces.
Example
Shut down the first T1 line on the T3 interface.
