Perform the following configuration in CT3 interface view.

By default, the CT3 interface works in channelized mode.

When the CT3 interface is working in unchannelized mode, the system 
automatically creates a serial interface numbered 

serial number / 0:0

 for it. 

This interface operates at 44.736 Mbps and has the same logic features of a 
synchronous serial interface on which you can make other configurations.

When the CT3 interface is working in channelized mode, you can demultiplex it 
into 28 T1 lines at 1.544 Mbps and set their operating modes separately.
