CE1/PRI interface view

ce1: Sets the interface to operate in CE1/PRI mode.

e1: Sets the interface to operate in E1 mode.

Use the using command to configure the operating mode of the CE1/PRI 
interface.

Use the undo using command to restore the default, that is, CE1/PRI mode.

A CE1/PRI interface can work in either E1 mode (non-channelized mode) or 
CE1/PRI mode (channelized mode).

In E1 mode, the interface equals a 2 Mbps interface without timeslot division. Its 
logical features are the same like those of a synchronous serial interface. In 
CE1/PRI mode, it is physically divided into 32 timeslots numbered 0 through 31, 
where timeslot 0 is used for FSC. This interface can work as either a CE1 interface 
or a PRI interface.

After you set the CE1/PRI interface to work in E1 mode, the system automatically 
creates a serial interface numbered serial interface-number:0, where 
interface-number represents the number of the CE1/PRI interface.

# Set CE1/PRI interface E1 2/0 to work in E1 mode.
