Receive E-bit Interrupt. When unmasked an interrupt is initiated when a receive E-bit indi-
cates a remote CRC-4 error. 1 - unmasked, 0 - masked. Interrupt vector = 00100000.
CRC-4 Error Interrupt. When unmasked an interrupt is initiated when a local CRC-4 error
occurs. 1 - unmasked, 0 - masked. Interrupt vector = 00100000.
Consecutively Errored FASs Interrupt. When unmasked an interrupt is initiated when two
consecutive errored frame alignment signals are received. 1 - unmasked, 0 - masked.
Interrupt vector = 00100000.
Bipolar Violation Interrupt. When unmasked an interrupt is initiated when a bipolar violation
error occurs. 1 - unmasked, 0 - masked. Interrupt vector = 00100000.
RAI and Continuous CRC Error Interrupt. When unmasked an interrupt is initiated when
the RAI and continuous CRC error counter is incremented. 1 - unmasked, 0 - masked.
Interrupt vector = 00100000.
Bit Error Interrupt. When unmasked an interrupt is initiated when a bit error occurs. 1 -
unmasked, 0 - masked. Interrupt vector = 00100000.
Unused.
Signalling (CAS) Interrupt. When unmasked and any of the receive ABCD bits of any chan-
nel changes state an interrupt is initiated. 1 - unmasked, 0 - masked. Interrupt vector =
00000001
Receive E-bit Counter Overflow Interrupt. When unmasked an interrupt is initiated when the
E-bit error counter changes form FFH to 0H. 1 - unmasked, 0 - masked. Interrupt vector =
00010000.
CRC-4 Error Counter Overflow Interrupt. When unmasked an interrupt is initiated when the
CRC-4 error counter changes form FFH to 0H. 1 - unmasked, 0 - masked. Interrupt vector =
00010000.
CRC-4 Alignment Interrupt. When unmasked an interrupt is initiated when the CALN status
bit of page 3, address 12H changes state. 1 - unmasked, 0 - masked. Interrupt vector =
00001000.
Frame Alignment Signal Error Counter Overflow Interrupt. When unmasked an interrupt is
initiated when the frame alignment signal error counter changes form FFH to 0H. 1 -
unmasked, 0 - masked. Interrupt vector = 00010000.
RAI and Continuous CRC-4 Error Counter Overflow Interrupt. When unmasked an interrupt
is initiated when the RAI and Continuous error counter changes form FFH to 0H. 1 -
unmasked, 0 - masked. Interrupt vector = 00010000.
Bit Error Counter Overflow Interrupt. When unmasked an interrupt is initiated when the bit
error counter changes form FFH to 0H. 1 - unmasked, 0 - masked. Interrupt vector =
00010000.
Auxiliary Pattern Interrupt. When unmasked an interrupt is initiated when the AUXP status
bit of page 3, address 15H goes high. 1 - unmasked, 0 - masked. Interrupt vector =
01000000.
Unused.
