Issue 4, May 2007
VC3VcSQM
A mismatch has been detected between the received sequence number and an
inherently provisioned expected sequence number for this Virtual
Concatenation Group (VCG).
Transmission
sdhVCG
Prompt
Reported
The red fault LED is lit.
One or more received VC-3-Xv group members have equal sequence numbers.
Verify that the connections in the preceding network element(s) have been
provisioned correctly.
The sequence number is used to check that the ordering of the VC-3s within
the VC-3-Xv group has not been altered during transport.
®
TransLAN unit, and if there are one or more sequence mismatch defects for a
VCG, and the corresponding path termination functions have not detected any
signal fail condition, then
alarms are raised against all paths of the VCG, not only against the paths
which actually have a sequence mismatch.
