Receive E-bit Interrupt. When unmasked an interrupt is initiated when a
receive E-bit indicates 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 received A bit has been one, and the received E bits
have been zero, continuously for greater than 10 milliseconds (see page
04H, address 19H) 1- unmasked, 0 - masked. Interrupt vector = 00100000.
RAI and Continuous CRC Error Interrupt. When unmasked an interrupt
is initiated when the received A bit had been set, and the received E bits
were low, continuously for greater than 10 milliseconds, but less than 450
milliseconds (see page 04H, address 19H). 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.
Signalling (CAS) Interrupt. When unmasked and any of the receive ABCD
bits of any channel changes state an interrupt is initiated. 1 - unmasked, 0 -
masked. Interrupt vector = 00000001
