Table 93 - Interrupt Mask Word Three (E1)

Unused
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.
One Second Status Interrupt Mask. When unmasked (1SECI = 1), an
interrupt is initiated when the 1SEC status bit changes from zero to one. If
1 - unmasked, 0 - masked.
Five Second Status Interrupt Mask. When unmasked (5SECI = 1), an
interrupt is initiated when the 5SECI status bit changes from zero to one. If
1 - unmasked, 0 - masked.
RCRI Interrupt Mask. When 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.
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.
Frame Alignment Signal Error Counter Overflow Interrupt Mask.
When unmasked an interrupt is initiated when the frame alignment signal
error counter overflows. If 1 - unmasked, 0 - masked.
CRC-4 Error Counter Overflow Interrupt. When unmasked an interrupt
is initiated when the CRC-4 error counter overflows. If 1 - unmasked, 0 -
masked.
Receive E-bit Counter Overflow Interrupt. When unmasked an
interrupt is initiated when the E-bit error counter overflows. If 1 -
unmasked, 0 - masked.
Unused.
Bipolar Violation Counter Overflow Interrupt. When unmasked
(BPVO = 1), an interrupt is initiated when the bipolar violation error
counter changes form FFFFH to 0H. If 1 - unmasked, 0 - masked.
PRBS Counter Overflow 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 Interrupt When unmasked an
interrupt will be generated whenever the multiframe counter attached to
the PRBS error counter overflows. If 1 - unmasked, 0 - masked.
Unused.
