. This interface can operate at N x 64 Kbps 

and has the same logic features of a synchronous serial interface on which you 
make other configurations.

Displaying and debugging the CE3 interface information includes the tasks of 
shutting down the interface and displaying the interface information. As shutting 
down an interface will make the interface stop working, you are recommended to 
use the 

 command only when necessary.

Perform the following configuration in CE3 interface view.

Disabling/Enabling a CE3 interface will also enable/disable the E1 lines 
demultiplexed from the CE3 interface, the serial interfaces formed by the E1 lines, 
and the serial interfaces that the E1 lines form by means of timeslot bundling.

Disabling/Enabling an E1 line will also disable/enable the serial interface formed by 
it and the serial interface that it forms by means of timeslot bundling.

To disable/enable only a serial interface formed by E3 or E1 line, or by timeslot 
bundling on an E1 line, you can perform the 

/

 command 

in the view of the corresponding serial interface.

Perform the following configuration in any view.

This section describes how to configure a CT3 interface.

Both T3 and T1 belong to the T-carrier system promoted by ANSI. T3 uses the 
digital signal level DS-3 and operates at 44.736 Mbps.

CT3 interfaces support two operating modes, that is, T3 (unchannelized) mode 
and CT3 (channelized) mode.

■

A CT3 interface in T3 mode equals a synchronous serial interface of 44736 
kbps data bandwidth, on which, no timeslots are divided.
