SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR FOR 622 MBIT/S
INTERFACES
activated. Interrupts disabled at tributary payload processor #3 will not be
reported by the VTPP3I bit.
LOM1E:
The LOM1E bit is an interrupt enable bit for the H4 framer out of frame
interrupt in tributary payload processor #1. When LOM1E is set high, a
change in the framer out of frame status will cause an interrupt to be
generated on the INTB output. Interrupts are masked when LOME is set low.
LOM2E:
The LOM2E bit is an interrupt enable bit for the H4 framer out of frame
interrupt in tributary payload processor #2. When LOM2E is set high, a
change in the framer out of frame status will cause an interrupt to be
generated on the INTB output. Interrupts are masked when LOME is set low.
When ICONCAT is set to logic 1 this interrupt enable bit should be set to logic
0. In the AU4 mode the multiframe alignment is determined by the H4 byte
framer in tributary payload processor #1.
LOM3E:
The LOM3E bit is an interrupt enable bit for the H4 framer out of frame
interrupt in tributary payload processor #3. When LOM3E is set high, a
change in the framer out of frame status will cause an interrupt to be
generated on the INTB output. Interrupts are masked when LOME is set low.
When ICONCAT is set to logic 1 this interrupt enable bit should be set to logic
0. In the AU4 mode the multiframe alignment is determined by the H4 byte
framer in tributary payload processor #1.
