0
Receive FERF (Far-End Receive Failure) Alarm:
0: The Receive DS3 Framer block is NOT currently declaring the “FERF”
condition.
1: The Receive DS3 Framer block is currently declaring the “FERF” condi-
tion.
3Rx AIC
RO
0
Receive AIC (Application Identification Channe) State:
0: Indicates that the AIC bit-field was set to “0” within two or more of the last
15 M-frames. This indicates that the inbound DS3 data stream is of the “M13
Framing” format.
1: Incoming frame is found to be in the C-bit format (AIC bit = 1) for at least
63 consecutive M-frames. This indicates that the inbound DS3 data stream
is of the “C-bit Parity” Framing format.
2
Rx FEBE(2)
RO
0
Received FEBE (Far-End-Block Error) Value:
RxFEBE[2:0] contains the value of the most recently received FEBE value.
When RxFEBE[2:0] = 011, this indicates that the Remote Terminal has
detected CP-bits or Framing Bit Errors in its DS3 data stream.
When RxFEBE[2:0] = 111, this indicates that the Remote Terminal is not cur-
rently detecting any Framing Bit or CP-bit errors in its DS3 data stream.
NOTE: These bit-fields are only active if the XRT72L71 is configured to sup-
port the “C-bit Parity” Framing format.
