By default, E1 lines are up.
This command affects not only the specified E1 line but also the serial interfaces
formed by E1 line bundling. Performing the e1 shutdown command on the
specified E1 line shuts down all these serial interfaces. Data transmission and
receiving stop as a result. Likewise, performing the undo e1 shutdown command
restarts all these serial interfaces.
Example # Shut down the first E1 line on interface E3 2/0.
<Sysname> system-view
[Sysname] controller e3 2/0
[Sysname-E3 2/0] e1 1 shutdown
e1 unframed
Syntax e1 line-number unframed
undo e1 line-number unframed
View CE3 interface view
Parameter line-number: E1 line number in the range 1 to 16.
Description Use the
e1 unframed command to set an E1 line on the CE3 interface to work in
unframed mode (E1 mode).
Use the
undo e1 unframed command to restore the default.
By default, an E1 line operates in framed mode (CE1 mode).
An E1 line in unframed mode does not contain the frame control information; it
cannot be divided into timeslots. The system automatically creates a serial
interface numbered serial number/line-number:0 for it. This interface operates at
2048 kbps and is logically equivalent to a synchronous serial interface on which
you can make other configurations.
Related command: e1 channel-set.
Example # Set the first E1 line on interface E3 2/0 to operate in unframed mode.
<Sysname> system-view
[Sysname] controller e3 2/0
[Sysname-E3 2/0] e1 1 unframed
