Step Command Remarks
8. Configure the SOH and
higher-order path overhead
bytes.
• flag { c2 path-number c2-value
| s1 s1-value | s1s0
path-number s1s0-value }
• flag { j0 | j1 path-number }
{ sdh | sonet } flag-value
Optional.
• The default value of c2 is 0x02
(hexadecimal) and s1 is 0x0f
(hexadecimal). The default
value of s1s0 is 0x0 for SONET
and 0x2 for SDH.
• For SONET frames, the default
value of j0 is 0x01 and that of
j1 is null; for SDH frames, the
initial values (for example, the
value when the router is initially
powered on) of both j0 and j1
are SR8800, and the values
change to null after a change in
the framing format.
9. Restore the default settings. default Optional.
10. Shut down the CPOS
interface.
shutdown
Optional.
By default, a CPOS interface is up.
11. Bring up the CPOS interface. undo shutdown
Optional.
By default, a CPOS interface is up.
12. Configure the signal degrade
(SD) threshold and the signal
fail (SF) threshold. threshold { sd | sf } value
Optional.
By default, the SD alarm threshold
is 10e-6; the SF alarm threshold is
10e-4 for PIC-CLF2G8L and
PIC-CLF4G8L CPOS sub-cards and
10e-3 for other types of CPOS
sub-cards.
13. Configure E1/T1/E3/T3
channel attributes.
• See “ Configuring an E1
channel .”
• See “ Configuring a T1
channel .”
• See “ Configuring an E3
channel .”
• See “ Configuring a T3
channel .”
Optional.
NOTE:
•
E1 configuration is supported on the CPOS(E) interface module but T1 configuration is supported on the
CPOS (T) interface module.
• If no cable is connected to a physical interface, shut down the interface with the shutdown command to
prevent anomalies caused by interference.
• Use the shutdown command with caution, because once an interface is shut down, it stops operating.
