Type
This bit indicates the value of the Remote Alarm Indication (A) bit.
= 0: The ‘A’ bit is logic 0.
= 1: RAI is detected according to the criterion set in the RAIC (b3, E1-031H). When the RAIC is ‘0’, RAI is detected when the ‘A’ bit is received as
The RAIV is updated every two frames.
This bit indicates the value of the Remote Signaling Multi-Frame Alarm Indication (Y) bit.
= 0: The ‘Y’ bit is logic 0.
= 1: Logic 1 has been received in ‘Y’ bit for 3 consecutive Signaling Multi-Frames.
The RMAIV is updated every 16 frames.
This bit indicates the Alarm Indication Signal (AIS) detect value. The detection of AIS is disabled in unframed mode.
= 0: AIS is clear according to the criterion set in the AISC (b1, E1-031H). When the AISC is ‘0’, AIS is clear when 3 or more zeros are detected in
= 1: AIS is detected according to the criterion set in the AISC (b1, E1-031H). When the AISC is ‘0’, AIS is detected when it is out of Basic frame
The AISD bit is updated once every 512 bit periods.
= 0: Out of Basic frame synchronization has been absent for 100 ms.
= 1: Out of Basic frame synchronization has persisted for 100 ms.
= 0: The condition of AIS has been absent for 100 ms.
= 1: The condition of AIS has persisted for 100 ms.
