Information About T1 Interfaces
The following sections provide information about T1 interfaces.
Overview of T1 Interfaces
The 12-port T1 interface module on CEM line card supports generic single or dual-port T1 trunk interfaces for voice, data, and integrated voice or data applications.
Configuring the Controller
To configure T1 interface, use the following commands:
enable configure terminal controller mediatype 0/4/0 mode t1 exit controller t1 0/4/0 clock source internal framing esf cablelength short 110 linecode b8zs no shutdown exit
Verifying Controller Configuration
Use show controllers command to verify the controller configuration:
#show controller t1 0/4/0 T1 0/4/0 is up Applique type is NCS4200-3GMS No alarms detected. alarm-trigger is not set Soaking time: 3, Clearance time: 10 AIS State:Clear LOS State:Clear LOF State:Clear Framing is unframed, Clock Source is Recovered Clock 0.
