INTERFACES
and to clear the interrupt. Interrupts disabled at tributary payload processor #3
will not be reported by the VTPP3I bit.
LOM1V:
The LOM1V bit indicates the status of the H4 byte framer in tributary payload
processor #1. LOM1V is set high when the H4 framer is in loss of multiframe
state and is set low when it re-acquires multiframe alignment.
LOM2V:
The LOM2V bit indicates the status of the H4 byte framer in tributary payload
processor #2. LOM2V is set high when the H4 framer is in loss of multiframe
state and is set low when it re-acquires multiframe alignment. When
ICONCAT is set to logic 1 this status bit should be ignored since the
multiframe alignment is determined by the H4 byte framer in tributary payload
processor #1.
LOM3V:
The LOM3V bit indicates the status of the H4 byte framer in tributary payload
processor #3. LOM3V is set high when the H4 framer is in loss of multiframe
state and is set low when it re-acquires multiframe alignment. When
ICONCAT is set to logic 1 this status bit should be ignored since the
multiframe alignment is determined by the H4 byte framer in tributary payload
processor #1.
