Optional.
Disabled by default.
15. Set the intended bandwidth
for the CE1/PRI interface.
bandwidth bandwidth-value Optional.
16. Set the physical state change
suppression interval for the
CE1/PRI interface.

Optional.
By default, state change
suppression is disabled.
17. Restore the default settings for
the CE1/PRI interface.

20. Enter the view of the
synchronous serial interface
created on the CE1/PRI
interface.

Optional.
By default, 16-bit CRC is adopted.
Configuring error packets diffusion restraint
Error packets diffusion refers to the situation when one timeslot receives a certain error packet. All the
other timeslots are affected, and they also receive error packets.
You can restrain error packet diffusion by configuring three parameters: detect-timer, renew-timer,
threshold, which function in the following way:
If, during the time specified by detect-timer, the ratio of error packets on an interface is greater than that
specified by threshold, the interface is regarded as faulty and is shut down. After waiting for some time
specified by renew-timer, the interface is brought up again.
To configure error packets diffusion restraint:

Optional.
By default, the value of detect-timer
is 30 seconds, of renew-timer is
600 seconds; the threshold is 20%.
4. Restart the channel that is shut
down for the sake of error
