R2511-HP MSR Router Series Interface Command Reference(V5)

193
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 to operate in unframed mode.
<Sysname> system-view
[Sysname] controller e3 2/0
[Sysname-E3 2/0] e1 1 unframed

0: Specifies the Digital Link mode, where the subrate is a multiple of 358 kbps. The subrate is in the range
of 358 to 34010 kbps. Up to 95 rate levels are available.
1: Specifies the Kentrox mode, where the subrate is a multiple of 500 kbps. The subrate is in the range
of 500 to 24500 kbps. In this mode, the subrate can also be 34010 kbps (making a total of 50 rate
levels).
subrate number: Specifies a subrate for the CE3 interface. The number argument is in the range of 1 to
34010 (in kbps).
