Table 90 - Interrupt Mask Word Zero (E1)
Table 91 - Interrupt Mask Word One (E1)
Loss of Signal Interrupt Mask. When unmasked this interrupt bit goes
high whenever a change of state of loss of signal (either analog - received
signal 20 or 40 dB below nominal or digital - 192 consecutive 0’s received)
condition exists. If 1 - unmasked, 0 - masked.
Consecutively Errored FASs Interrupt Mask. When unmasked an
interrupt is initiated when two consecutive errored frame alignment signals
are received. If 1 - unmasked, 0 - masked.
Remote Signaling Multiframe Alarm Interrupt Mask. When unmasked
(YI=1), an interrupt is initiated whenever a change of state of remote
signaling multiframe alarm signal is received. If 1 - unmasked, 0 - masked.
SLIP Interrupt Mask. When unmasked (SLPI=1), an interrupt is initiated
when a controlled frame slip occurs. If 1 - unmasked, 0 - masked.
Frame Error Interrupt Mask. When unmasked (FERI = 1), an interrupt is
initiated when an error in the frame alignment signal occurs. If 1 -
unmasked, 0 - masked.
CRC-4 Error Interrupt Mask. When unmasked an interrupt is initiated
when a local CRC-4 error occurs. 1 - unmasked, 0 - masked. If 1 -
unmasked, 0 - masked.
Receive E-bit Interrupt Mask. When unmasked an interrupt is initiated
when a receive E-bit indicates a remote CRC-4 error. 1 - unmasked, 0 -
masked. If 1 - unmasked, 0 - masked.
Channel 16 Alarm Indication Signal Interrupt Mask. When unmasked
(AIS16I = 1), a received AIS16 will initiate an interrupt. If 1 - unmasked, 0 -
masked.
Bipolar Violation Interrupt Mask. When unmasked an interrupt is
initiated when a bipolar violation error occurs. 1 - unmasked, 0 - masked.
PRBS Interrupt Mask. When unmasked (PRBSI = 1), an interrupt is
initiated on a single PRBS detection error. If 1 - unmasked, 0 - masked.
Auxiliary Pattern Interrupt Mask. When unmasked (AUXPI = 1), an
interrupt is initiated when the AUXP status bit of page 03H, address 15H
goes high. If 1 - unmasked, 0 - masked.
Remote Alarm Indication Interrupt Mask. When unmasked (RAII = 1) a
received RAI will initiate an interrupt. If 1 - unmasked, 0 - masked.
