LAISV
LRDIV
APSBFV
The LAISV bit reflects the current status of the line alarm indication signal defect. The AIS-
L defect is declared when the 111 pattern is detected in bits 6,7 and 8 of the K2 byte for three
or five consecutive frames. The AIS-L defect is cleared when any pattern other than 111 is
detected in bits 6, 7, and 8 of the K2 byte for three or five consecutive frames.
The LRDIV bit reflects the current status of the line remote defect indication signal defect.
The RDI-L defect is declared when the 110 pattern is detected in bits 6, 7, and 8 of the K2
byte for three or five consecutive frames. The RDI-L defect is cleared when any pattern other
than 110 is detected in bits 6, 7, and 8 of the K2 byte for three or five consecutive frames.
The APSBF bit reflects the current status of the APS byte failure defect. The APS byte
failure defect is declared when no three consecutive identical K1 bytes are received in the last
twelve consecutive frames starting with the last frame containing a previously consistent
byte. The APS byte failure defect is cleared when three consecutive identical K1 bytes are
received.
