DESCRIPTION
Receive UTOPIA/POS-PHY Interface Block Interrupt Status:
This READ-ONLY bit-field indicates whether or not a "Receive
UTOPIA/POS-PHY Interface" block interrupt is awaiting service.
0 - No "Receive UTOPIA/POS-PHY Interface" block interrupt is
awaiting service.
1 - At least one "Receive UTOPIA/POS-PHY Interface" block
interrupt is awaiting service.
Receive ATM Cell/PPP Processor Block Interrupt Status:
This READ-ONLY bit-field indicates whether or not a "Receive
ATM Cell/PPP Processor Block" Interrupt is awaiting service.
0 - No "Receive ATM Cell/PPP Processor block" interrupt is
awaiting service.
1 - At least one "Receive ATM Cell/PPP Processor" block inter-
rupt is awaiting service.
Transmit UTOPIA/POS-PHY Interface Block Interrupt Status:
This READ-ONLY bit-field indicates whether or not a "Transmit
UTOPIA/POS-PHY Interface" block interrupt is awaiting service.
0 - No "Transmit UTOPIA/POS-PHY Interface" block interrupt is
awaiting service.
1 - At least one "Transmit UTOPIA/POS-PHY Interface" block
interrupt is awaiting service.
Receive ATM Cell/PPP Processor Block Interrupt Status:
