e1 unframed
Use e1 unframed to set an E1 line on the CE3 interface to operate in unframed mode (E1 mode).
Use undo e1 unframed to restore the default.
Syntax
e1 line-number unframed
undo e1 line-number unframed
Default
An E1 line operates in framed mode (CE1 mode).
Views
CE3 interface view
Default command level
2: System level
Parameters
line-number: E1 line number in the range of 1 to 16.
Usage guidelines
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.
Examples
# Set the first E1 line on interface E3 2/0/0 to operate in unframed mode.
<Sysname> system-view
[Sysname] controller e3 2/0/0
[Sysname-E3 2/0/0] e1 1 unframed
