e1 unframed
loopback
Command Reference Guide
By default, E1 line is enabled.
This command will affect not only the specified E1 line but also the serial
interfaces formed by bundling the timeslots of the E1 line. Executing the e1
shutdown command on the specified E1 line will shut down all these serial
interfaces and the data transmission and receiving will be stopped as a result.
Likewise, executing the undo e1 shutdown command will re-enable all these
serial interfaces.
Example
Shut down the first E1 line on the E3 interface.
[NEC-PHILIPS-E3 1/0/0]e1 1 shutdown
Syntax
e1 line-number unframed
undo e1 line-number unframed
View
CE3 interface view
Parameter
line-number: E1 line number in the range of 1 to 16.
Description
Using the e1 unframed command, you can set an E1 line on a CE3 interface to
work in unframed mode (E1 mode). Using the undo e1 unframed command,
you can set the E1 line on the CE3 interface to work in framed mode (CE1
mode).
By default, E1 lines are working in framed mode.
An E1 line in unframed mode does not contain the frame control information
and cannot be divided into timeslots. Naturally, no timeslot bundling can be
performed on it. In this case, the system automatically creates a serial interface
numbered serial number / line-number:0 for it. This interface operates at 2048
Kbps and has the same logic features of a synchronous serial interface on
which you can make other configurations.
For related command, see e1 channel-set.
Example
Set the first E1 line on the E3 interface to work in unframed mode.
[NEC-PHILIPS-E3 1/0/0]e1 1 unframed
Syntax
loopback { local | payload | remote }
undo loopback
View
CE3 interface view
Parameter
local: Enables the CE3 interface to perform local loopback.
payload: Places the CE3 interface in an remote payload loopback. Data passes
the framer in this case and will be looped back after payload is generated.
