6.
Set overhead bytes for the
E1 channel.
e1
e1-number
flag c2
c2-value
e1
e1-number
flag j2
{
sdh
|
sonet
}
j2-string
By default, C2 is set to
hexadecimal
02
, and J2 contains
cyclic empty character strings.
7.
Configure the E1 channel
operating mode.
•
Specify the unframed mode:
e1
e1-number
unframed
•
Specify the framed mode
and bundle timeslots:
a.
(Optional.)
undo e1
e1-number
unframed
b. e1
e1-number
channel-set
set-number
timeslot-list
range
By default, an E1 channel
operates in framed mode and is
not channelized.
When you place an E1 channel in
unframed mode, the system
automatically creates a 2.048
Mbps serial interface.
When you bundle timeslots on an
E1 channel in framed mode, the
system automatically creates a
serial interface for the bundle. The
rate of the serial interface is
identical to 64 kbps x number of
bundled timeslots.
8.
(Optional.) Shut down the
specified E1 channel.
e1
e1-number
shutdown
By default, an E1 channel is up.
Configuring a T1 channel
The serial interface created for T1 channels have the same logical features as a synchronous serial
interface. You can configure these serial interfaces in the same way you configure a standard
synchronous serial interface. For more information about configuring synchronous serial interfaces,
see "

The default setting is slave.
5.
(Optional.) Enable loopback
on the T1 channel.

By default, loopback is disabled.
6.

t1
t1-number
flag j2
{
sdh
