Bit
Name
Functional Description
7
TFSYNI Terminal Frame Synchronization Interrupt. When unmasked this interrupt bit goes high
whenever a change of state of terminal frame synchronization condition exists. Reading this
register clears this bit.
6
MFSYNI Multiframe Synchronization Interrupt. When unmasked this interrupt bit goes high
whenever a change of state of multiframe synchronization condition exists. Reading this
register clears this bit.
5
4
3
BIOMTI Bit Oiented Message Transition Interrupt. When unmasked, this interrupt goes high
whenever a new BIOM arrives or if the current BIOM stops transmission.
AISI
Alarm Indication Signal Interrupt. When unmasked this interrupt bit goes high whenever a
change of state of received all ones condition exists. Reading this register clears this bit.
LOSI
Loss of Signal Interrupt. When unmasked this interrupt bit goes high whenever a change of
state of loss of signal (either analog - signal 40 dB below nominal or digital - excess
consecutive 0’s received) condition exists. Reading this register clears this bit.

SEI
Severely Errored Frame Interrupt. When unmasked this interrupt bit goes high whenever a
sequence of 2 framing errors out of 6 occurs. Reading this register clears this bit.
TxSLPI Transmit SLIP Interrupt. When unmasked this interrupt goes high whenever a controlled
frame slip occurs in the transmit elastic buffer. Reading this register clears this bit.
RxSLPI Receive SLIP Interrupt. When unmasked this interrupt bit goes high whenever a controlled
frame slip occurs in the receive elastic buffer. Reading this register clears this bit.
