Table 33 - Interrupt Mask Word One (T1)
Table 34 - Interrupt Mask Word Two (T1)
Pulse Density Violation Interrupt Mask. When unmasked an interrupt is
triggered whenever a sequence of excessive consecutive zeros is received
on the line, or the incoming pulse density is less than N ones in a time
frame of 8(N+1) where N = 1 to 23. If 1 - unmasked, 0 - masked.
Unused.
Framing Bit Error Counter Overflow Interrupt Mask. When unmasked
an interrupt is initiated whenever the framing bit error counter changes
from FFH to 00H. If 1 - unmasked, 0 - masked.
CRC-6 Error Counter Overflow Interrupt Mask. When unmasked an
interrupt is initiated whenever the CRC-6 error counter changes from FFH
to 00H. If 1 - unmasked, 0 - masked.
Out Of Frame Counter Overflow Interrupt Mask. When unmasked an
interrupt is initiated whenever the out of frame counter changes state from
changes from FFH to 00H. If 1 - unmasked, 0 - masked.
Change of Frame Alignment Counter Overflow Interrupt Mask. When
unmasked an interrupt is initiated whenever the change of frame alignment
counter changes from FFH to 00H. If 1 - unmasked, 0 - masked.
Bipolar Violation Counter Overflow Interrupt Mask. When unmasked an
interrupt is initiated whenever the bipolar violation counter changes from
FFH to 00H. If 1- unmasked, 0 - masked.
Psuedo Random Bit Sequence Error Counter Overflow Interrupt
Mask. When unmasked an interrupt will be generated whenever the PRBS
error counter changes from FFH to 00H. If 1 - unmasked, 0 - masked.
Psuedo Random Bit Sequence Multiframe Counter Overflow Interrupt
Mask. When unmasked an interrupt will be generated whenever the
multiframe counter attached to the PRBS error counter overflows. FFH to
00H. If 1 - unmasked, 0 - masked.
Multiframes Out Of Sync Overflow Interrupt Mask. When unmasked an
interrupt will be generated when the multiframes out of frame counter
changes from FFH to 00H. If 1 - unmasked, 0 - masked.
