Command Remarks
3. Set the interface description.
description text
Optional.
By default, the description of an
E-CPOS interface is interface
name Interface, for example,
E-Cpos5/1/0 Interface.
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 J0 byte.
flag j0 { sdh j0-string | sonet
j0-value }
Optional.
8. Configure the signal degrade
(SD) alarm threshold and
signal fail (SF) alarm
threshold.
threshold { sd | sf } value
Optional.
By default, the SD alarm
threshold is 10e-6 (the value
argument is 6), and the SF alarm
threshold is 10e-3 (the value
argument is 3).
9. Set the physical state change
suppression interval.
link-delay seconds
Optional.
By default, physical state change
suppression is disabled on the
interface.
10. Set the intended bandwidth
for the E-CPOS interface.
bandwidth bandwidth-value 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 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.
• STM-1 E-CPOS interfaces (at 155 Mbps), which can be channelized into 155 Mbps POS channels.
