8.
Configure the SOH and
higher-order path overhead
bytes.

{
c2
path-number c2-value
|
s1s0
path-number s1s0-value
}
flag
{
j0
|
j1

}
flag-value
By default:
•
c2
is 0x02.
•
s1s0
is 0x00 for SONET and
0x02 for SDH.
•
j0
is 0x01 for SONET and a
16-byte empty character
string for SDH.
•
j1
is a 64-byte empty
character string for SONET
and a 16-byte empty
character string for SDH.
9.
Set the physical state
change suppression interval
on the interface.
link-delay
seconds
By default, the physical state
change suppression interval is 0
seconds.
10.
Set the signal degrade (SD)
or signal fail (SF) alarm
threshold for the interface.
threshold
{
sd
sdvalue
|
sf
sfvalue
} *
By default, the SD threshold is
10e to the power of negative 6
(10e
–6
) and the SF threshold is
10e to the power of negative
3
(10e
–3
).
11.
(Optional.) Configure the
action to take when an RDI,
SD, or SF alarm occurs on
the CPOS interface.
alarm-detect
{
rdi
|
sd
|
sf
}
action
link-down
By default, the device does not
take any actions on the interface
when an RDI, SD, or SF alarm
occurs.
12.
(Optional.) Restore the
default settings for the CPOS
interface.
default
N/A
13.
Bring up the CPOS interface.
undo shutdown
By default, a CPOS interface is
up.
If no cable is connected to a
physical interface, shut down the
interface with the
shutdown
command to prevent problems.
Configuring an E1 channel
The serial interfaces created for E1 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 "

To configure an E1 channel:

3.
Set the framing format for the
E1 channel.
e1
e1-number
frame-format
{
crc4
|
no-crc4
}
The default setting is no-CRC4.
4.
Set the clock mode for the E1
channel.
e1
e1-number

}
The default setting is slave.
5.
(Optional.) Enable loopback
on the E1 channel.
