Table 127 - Interrupt Word One
(Page 4, Address 1CH) (E1)
Errored Framing Alignment Signal Interrupt. When unmasked
this interrupt bit goes high whenever an erroneous bit in frame
alignment signal is detected (provided the circuit is in terminal frame
sync). Reading this register clears this bit.
CRC-4 Error Interrupt. When unmasked this interrupt bit goes high
whenever a local CRC-4 error occurs. Reading this register clears
this bit.
Receive E-bit Error Interrupt. When unmasked this interrupt bit
goes high upon detection of a wrong E-bit in multiframe. Reading
this register clears this bit.
Alarm Indication Signal Interrupt. When unmasked this interrupt
bit goes high whenever all ones in time slot 16 occur.Reading this
register clears this bit.
Bipolar Violation Interrupt. When unmasked this interrupt bit goes
high whenever a bipolar violation (excluding HDB3 encoding) is
encountered. Reading this register clears this bit.
Pseudo Random Bit Sequence Error Interrupt. When unmasked
this interrupt bit goes high upon detection of an error with a channel
selected for PRBS testing. Reading this register clears this bit.
Auxiliary Pattern Alarm Interrupt. When unmasked this interrupt
bit goes high whenever a sequence of 512 bit consecutive 101010.
occur. Reading this register clears this bit.
Remote alarm Indication Interrupt. When unmasked this interrupt
bit goes high
whenever the bit 3 of non-frame alignment signal is high. Reading
this register clears this bit.
