Standing Conditions
LTC-TCMB (TCM_B-Connection Loss)
The corresponding SNMP name for this condition is
“lossofTandemConnectionOduTcmB”.
AIDTYPE Default
Severity
Probable Cause Suggested Corrective Action
CH MN The facility has
received a signal in
which the tandem
connection monitoring
overhead for the TCMi
layer assigned as
instance “B” contains
the “No source TC”
code (“000” in the
STAT field, bits 6
through 8 of byte 3 in
the TCM overhead)
indicating that the far-
end tandem
connection
termination point has
not been provisioned.
This is caused by
assigning an unused
TCMi to this instance.
1 Verify that the correct TCMi has
been assigned to this instance
(i.e. verify the TCMB attribute
value).
2 Verify that the intended
upstream facility has the same
TCMi assigned to one of its
TCMA, TCMB or TCMC
attributes, and that the facility is
correctly provisioned in all other
respects and is in-service
normal (“In Service”).
3 Verify that there are no errors in
cabling or cross-connection at
each successive upstream
point along the trail back to the
far-end tandem connection
termination point.
