OAM Alarms and Loopbacks
66 Avidia System Configuration and Management User Manual
To perform this test, the user must be familiar with the OAM commands for the ATM node.
The user must specify
the:
• VPI/VCI for an OAM F5 flow VCC or VPI only for an OAM F4 flow VPC
• destination or target Location ID address (as defined at Point A) for an OAM loopback may
be required by some ATM nodes (the modem does not have a Location ID, so leave the
Destination Location ID as a default value if that value is different than the OAM Location
ID for the Avidia system)
ATM Node to Avidia Line Card Segment Loopback
The ATM node (beyond the ATM switch) to Avidia line card segment loopback originates
and terminates at the source
ATM node (point D). The loopback target or destination is the
Avidia line card (point B), as shown in the figure below. At the ATM node, the user must specify
for this test the:
• VPI/VCI for an OAM F5 flow VCC or VPI only for an OAM F4 flow VPC
