Minor Alarm Corrective Action
1
1. Applicable only if ERDI-P is enabled
AIS-L The problem originated from an upstream node; investigate nodes in
upstream direction
RFI-L
• Activate a line loopback at the remote node and isolate problem by
checking the looped signal
• Verify the physical connection (cables and connectors) in the MGX
8260 Media Gateway transmit direction
AIS-P The problem originated from an upstream node; investigate nodes in
upstream direction
RFI-P
• This is ok if MGX 8260 Media Gateway is currently transmitting AIS-P
to the remote node
• Otherwise, check for conditions on MGX 8260 Media Gateway that
could lead to LOP-P on the remote side
TIM-P
• Verify that the expected path trace identifier (J1) is configured properly
• Investigate why the remote node is transmitting a path trace identifier
that does not match the expected value
UNEQ-P
• Verify that the remote node has the signal label (C2) byte configured
properly
• Investigate why the remote node is transmitting a signal label that does
not match the expected value
PLM-P
• Verify that the remote node has the signal label (C2) byte configured
properly
• Investigate why the remote node is transmitting a signal label that does
not match the expected value
RFI-P server
• Not a problem if MGX8260 is currently transmitting AIS-P to the
remote node
• Otherwise, check for conditions on MGX8260 that could lead to LOP-P
on the remote side
RFI-P connectivity
• Check for conditions on MGX8260 that could lead to TIM-P or
UNEQ-P on the remote side
RFI-P payload
• Check for conditions on MGX8260 that could lead to PLM-P on the
remote side
Symptom Corrective Action
SCC in mismatch state
• Verify that both SCCs have the identical BIM and back card
configuration
OC3 line in major alarm
after SCC switch over
• Verify that the Y-cable set up is correct
• Prior to using a SCC as a stand by card, verify that all four OC3 lines
on that SCC can function properly
