This register provides interrupt status of the three H4 byte framers and of the
three tributary payload processors in the STP.
VTPP1I:
VTPP1I identifies tributary payload processor #1 as the source of a pending
interrupt. It is necessary to read the various interrupt status registers in
tributary payload processor #1 to determine the event causing the interrupt
and to clear the interrupt. Interrupts disabled at tributary payload processor #1
will not be reported by the VTPP1I bit.
VTPP2I:
VTPP2I identifies tributary payload processor #2 as the source of a pending
interrupt. It is necessary to read the various interrupt status registers in
tributary payload processor #2 to determine the event causing the interrupt
and to clear the interrupt. Interrupts disabled at tributary payload processor #2
will not be reported by the VTPP2I bit.
VTPP3I:
VTPP1I identifies tributary payload processor #3 as the source of a pending
interrupt. It is necessary to read the various interrupt status registers in
tributary payload processor #3 to determine the event causing the interrupt
