e1-number: Number of an E1 channel on the CPOS interface, in the range 1 to 63.

Use the e1 shutdown command to shut down an E1 channel.

Use the undo e1 shutdown command to bring up an E1 channel.

By default, E1 channels are enabled.

Disabling an E1 channel also disables the serial interfaces that are formed on it, if 
there is any.

e1-number: Number of an E1 channel on the CPOS interface, in the range 1 to 63.

Use the e1 unframed command to set an E1 channel on the CPOS interface to 
operate in unframed mode, that is, E1 mode.

Use the undo e1 unframed command to restore the default, that is, channelized 
mode.

So far, E1 channels on CPOS interfaces support two operating modes: clear 
channel (or unframed) and channelized.

■

In unframed mode, an E1 channel can form a 2.048 Mbps serial interface 
without timeslot division. It is named serial slot/port/e1-number:0.

■

In channelized mode, all timeslots except timeslot 0 on the E1 channel can be 
bundled arbitrarily to form serial interfaces. Considering the system processing
