Interframe Filling Tag
The interframe filling tag is the code sent when a timeslot in a logical channel does not send any
service data.
The AR1200 supports two types of interframe filling tags: 0x7e and 0xff and allows you to set
the minimum number of interframe filling tags.
RAI Detection
A remote alarm indication (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).
