e1 shutdown

Syntax e1 e1-numbershutdown undo e1 e1-numbershutdown

View CPOS interface view

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

Description 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.

Example # Shut down E1 channel 1.

<Sysname> system-view

[Sysname] controller cpos 1/0

[Sysname-Cpos1/0] e1 1 shutdown

e1 unframed

Syntax e1 e1-numberunframed undo e1 e1-numberunframed

View CPOS interface view

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

Description 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
