Step Command Remarks
15. Enable user data inversion.
data-coding { inverted | normal }
Optional.
Disabled by default.
16. Set the intended bandwidth
for the CE1 interface.
bandwidth bandwidth-value Optional.
17. Shut down the CE1 interface.

Optional.
Up by default.
18. Enter the view of the
synchronous serial interface
created on the CE1 interface.

19. Set the CRC mode.
crc { 16 | 32 | none }
Optional.
By default, 16-bit CRC is adopted.
Configuring error packets diffusion restraint
Error packets diffusion occurs when the error packet received on one timeslot spreads to other timeslots.
You can suppress error packet diffusion by configuring three parameters: detection period (detect-timer),
renew-timer (renew-timer), and PER threshold (threshold).
If the packet error rate for the detection period exceeds the PER threshold, the interface automatically
shuts down to avoid the risk of error packets diffusion. At the same time, the renew timer starts. When the
timer expires, the interface automatically comes up.
To configure error packets diffusion restraint:

Command Remarks
1. Enter system view.

Optional.
By default, the detect-timer is 30
seconds, the renew-timer is 600
seconds, and the PER threshold is
20%.
