Bit Name
Bit Name
This bit selects the AIS alarm detection criteria.
= 0: The criterion meets I.431. The AIS alarm will be declared when less than 3 zeros are detected in a 512-bit fixed window and it is out of Basic
frame synchronization, and the AIS alarm will be cleared when more than 2 zeros are detected in a 512-bit fixed window.
= 1: The criterion meets G.775. The AIS alarm will be declared when less than 3 zeros are detected in each of 2 consecutive 512-bit fixed window,
and the AIS alarm will be cleared when more than 2 zeros are detected in each of 2 consecutive 512-bit fixed window.
This bit selects the Remote alarm detection criterion.
= 0: The Remote alarm will be declared when 4 consecutive A bits are received as ‘1’, and the Remote alarm will be cleared when a single A bit is
received as ‘0’.
= 1: The Remote alarm will be declared when a single A bit is received as ‘1’, and the Remote alarm will be cleared when a single A bit is received
as ‘0’.
A transition from ‘0’ to ‘1’ on this bit updates all the PMON indirect registers.
= 0: Disable the automatic update function of the PMON indirect registers.
= 1: All the PMON indirect registers are updated every one second automatically.
