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.

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