Name
Set if any valid non-0 FEBE value (values 1–24) is detected in the M1 octet of the
STS-1/STS-3c/STM-1 overhead.
Set if the one-second timer input is detected.
Set if the received value in the C2 octet does not equal 0x13 for seven consecutive frames.
Set if a value of 9 is detected in the most significant nibble of the G1 octet of the
STS-1/STS-3c/STM-1 overhead.
Set if any valid non-0 FEBE value (values 1–8) is detected in the most significant nibble of
the G1 octet of the STS-1/STS-3c/STM-1 overhead.
Set if there is an error in any of the B1, B2, B3 BIP-8, or BIP-24 codes at the receiver.
Set if the three LSBs of the K2 octet are set to “110” for five consecutive frames.
Indicates that HEC cell delineation has been lost. Cell delineation is lost if seven consecutive
HEC errors occur at the current cell delineation position.
Set if STS LOF is high for three consecutive one-second latching signals (rising edge on
ONESECI).
Set when STS OOF is active for 24 consecutive SONET frames.
Set if four consecutive errored A1/A2 framing patterns are observed. For STS-3c/STM-1, the
pattern observed consists of the third A1 octet and the first A2 octet.
Set if the path yellow bit in the G1 octet is set for 10 consecutive frames. The RDI qualifier
for this alarm can be observed in bits 8 and 9 of the CONFIG_5 register.
Set if H1 and H2 octets are all 1s for three consecutive frames.
Set if the three LSBs of the K2 octet are set to “111” for five consecutive frames.
Set if a valid pointer as defined in TR-NWT-000253 cannot be found in the H1/H2 pointer of
the STS-1/STS-3c/STM-1 frame.
Set if there is a LOS detected by the RXLOS~ input pin. For STS-3c/STM-1, the only source
of LOS is RXLOS~. Cells will continue to be output on the receive side until LOCD is
detected, which is about 6 or 7 cells. To stop output of cells immediately, connect RXLOS~
to RCV_HLD after inverting.
