Interframe Filling Tag
The interframe filling tag is the code sent when the timeslot bundled to form a logical channel
does not send any service data.
The AR1200 supports two interframe filling tags: 0x7e and 0xff. On the AR1200, you can set
the minimum number of interframe filling tags.
AIS Detection
AIS alarms are also called upstream alarms, indicating that the peer device or the receive link
of the local device is faulty.
If the number of 0s in 512 consecutive bits (two consecutive frames) of a received signal is
smaller than 3, an AIS alarm is generated. If the number of 0s in 512 consecutive bits of a received
signal is larger than or equal to 3, an AIS alarm is cleared.
RAI Detection
An RAI alarm is sent to an upstream device after the AR1200 detects loss of frame (LoF) caused
by clock asynchronization or loss of signal (LOS).
