Table 125 - CRC-4 Error Counter CEt
Table 126 - Interrupt Word Zero
CRC-4 Error Counter. These are the least significant eight bits of the
CRC-4 error counter.
(Page 4, Address 19H) (E1)
Terminal Frame Synchronization Interrupt. When unmasked this
interrupt bit goes high whenever a change of state of terminal frame
synchronization condition exists. Reading this register clears this bit.
Multiframe Synchronization Interrupt. When unmasked this
interrupt bit goes high whenever a change of state of multiframe
synchronization condition exists. Reading this register clears this bit.
CRC-4 Synchronization Interrupt. When unmasked this interrupt bit
goes high whenever change of state of CRC-4 synchronization
condition exists. Reading this register clears this bit.
Alarm Indication Signal Interrupt. When unmasked this interrupt bit
goes high whenever a change of state of received all ones condition
exists. Reading this register clears this bit.
Loss of Signal Interrupt. When unmasked this interrupt bit goes high
whenever a loss of signal (either analog - received signal 20 or 40 dB
below nominal or digital - 192 consecutive 0’s received) condition
exists.
Consecutively
unmasked this interrupt bit goes high whenever the error in last two
frame alignment signals occurs. Reading this register clears this bit.
Receive Y-bit Interrupt. When unmasked this interrupt goes high
whenever a change of status loss of multiframe alignment occurs.
Reading this register clears this bit.
Receive SLIP Interrupt. When unmasked this interrupt bit goes high
whenever a controlled frame slip occurs in the receive elastic buffer.
Reading this register clears this bit.
