Table 32 - Interrupt Mask Word Zero (T1)
Table 33 - Interrupt Mask Word One (T1)
Terminal Frame Synchronization Interrupt Mask. When unmasked an
interrupt is initiated whenever a change of state of terminal frame
synchronization condition exists. If 1 - unmasked, 0 - masked.
Multiframe Synchronization Interrupt Mask. When unmasked an
interrupt is initiated whenever a change of state of multiframe
synchronization condition exist. If 1 - unmasked, 0 - masked.
Unused.
Alarm Indication Signal Interrupt Mask. When unmasked a change of
state of received all ones condition will initiate an interrupt. If 1 - unmasked,
0 - masked.
Loss of Signal Interrupt Mask. When unmasked an interrupt is initiated
whenever a change of state of loss of signal condition exists. If 1 -
unmasked, 0 - masked. Interrupt vector = 01000000.
Severely Errored Frame Interrupt Mask. When unmasked an interrupt is
initiated when a sequence of 2 framing errors out of 6 occurs. If 1 -
unmasked, 0 - masked.
Transmit SLIP Interrupt Mask. When unmasked an interrupt is initiated
whenever a controlled frame slip occurs in the transmit elastic buffer. If 1 -
unmasked, 0 - masked.
Receive SLIP Interrupt Mask. When unmasked an interrupt is initiated
whenever a controlled frame slip occurs in the receive elastic buffer. If 1 -
unmasked, 0 - masked.
Framing Bit Error Interrupt Mask. When unmasked an interrupt is
initiated whenever an erroneous framing bit is detected (provided the circuit
is in terminal frame sync). If 1 - unmasked, 0 - masked.
CRC-6 Error Interrupt Mask. When unmasked an interrupt is initiated
whenever a local CRC-6 error occurs. If 1 - unmasked, 0 - masked.
Yellow Alarm Interrupt Mask. When unmasked detection of a yellow
alarm triggers an interrupt. If 1 - unmasked, 0 - masked.
Change of Frame Alignment Interrupt Mask. When unmasked an
interrupt is initiated whenever a change of frame alignment occurs after a
reframe. If 1 - unmasked, 0 - masked.
Bipolar Violation Interrupt Mask. When unmasked an interrupt is initiated
whenever a bipolar violation (excluding B8ZS encoding) is encountered. If
1- unmasked, 0 - masked.
Psuedo Random Bit Sequence Error Interrupt Mask. When unmasked
an interrupt will be generated upon detection of an error with a channel
selected for PRBS testing. 1 - unmasked, 0 - masked.
