e1 shutdown
Syntax e1 e1-number shutdown
undo e1 e1-number shutdown
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-number unframed
undo e1 e1-number unframed
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
