Step Command Remarks
4. Set the framing format. frame-format { sdh | sonet }
Optional.
SDH by default.
5. Configure the clocking mode. clock { master | slave }
Optional.
Slave clocking mode by default.
6. Configure the loopback
mode.
loopback { local | remote }
Optional.
Disabled by default.
7. Configure the AUG
multiplexing path.
multiplex mode { au-3 | au-4 }
Optional.
AU-4 for SDH, and AU-3 for
SONET by default.
Only subcards PIC-CLS4G4L and
PIC-CHS1G4L support this
command.
8. Configure the J0 byte.
flag j0 { sdh j0-string | sonet
j0-value }
Optional.
9. Configure the signal degrade
(SD) threshold and signal fail
(SF) threshold.
threshold { sd | sf } value
Optional.
By default, the SD threshold is
10e-6 and the SF threshold is
10e-3.
10. Restore the default settings. default Optional.
11. Shut down the E-CPOS
interface.
shutdown
Optional.
Up by default.
NOTE:
•
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.
Configuring the operating mode of an E-CPOS
interface/channel
As mentioned earlier, E-CPOS interfaces are different from CPOS interfaces in rate hierarchy and
channelization hierarchy. The major types of E-CPOS interfaces supported currently include:
• STM-16 E-CPOS interfaces (at 2488 Mbps), which can be channelized into 2.5 Gbps/622
Mbps/155 Mbps POS channels.
• STM-4 E-CPOS interfaces (at 622 Mbps), which can be channelized into 622 Mbps/155 Mbps
POS channels or E3/T3 serial interfaces.
• STM-1 E-CPOS interfaces (at 155 Mbps), which can be channelized into 155 Mbps POS channels
or E3/T3 serial interfaces.
Configuring the interface/channel operating mode on a 2.5 Gbps E-CPOS interface
You can use the using command to configure a 2.5 Gbps E-CPOS interface to operate in channelized
mode or concatenated mode.
