Jitter Attenuation Interrupt Mask.
When unmasked, an interrupt will be
initiated when the jitter attenuator
FIFO comes within four bytes of an
overflow or underflow condition. If 1 -
unmasked, 0 - masked.
When unmasked (1SECI = 1), an
interrupt is initiated when the 1SEC
status bit changes from zero to one. If
1 - unmasked, 0 - masked.
When unmasked (5SECI = 1), an
interrupt is initiated when the 5SECI
status bit changes from zero to one. If
1 - unmasked, 0 - masked.
unmasked (RCRI=1), an interrupt is
initiated when RCR (remote alarm &
CRC-4 error) status bit changes from
zero to one. If 1 - unmasked, 0 -
masked.

Functional Description
PRBS
Interrupt. When unmasked
(PRBSO = 1), an interrupt is
initiated on overflow of PRBS
counter (page 04H, address
10H) from FFH to 0H. If 1 -
unmasked, 0 - masked.
PRBS MultiFrame Counter
Overflow
unmasked an interrupt will be
generated
multiframe counter attached
to the PRBS error counter
overflows. If 1 - unmasked, 0
- masked.

Signaling (CAS) Interrupt Mask.
When unmasked and any of the
receive ABCD bits of any channel
changes state an interrupt is initiated.
If 1 - unmasked, 0 - masked.
