Field Description
Auto PVC
The overall operation of the auto-sensing
PVC feature relies on end-to-end OAM
pings to defined PVCs. There are two
groups of PVCs:
•
Customer default PVCs - defined by
the ISP and the backup PVCs. It
must have 0/35 as the first default
PVC.
•
Backup list of PVCs - it must be of
the following VPI/VCI:
0/35, 8/35,
0/43, 0/51, 0/59, 8/43, 8/51
and
8/59.
These are defined in XLM and
are configurable.
The Auto-sensing PVC feature itself is also
configurable in that the auto-search
mechanism can be disabled.
Upon DSL synchronization, end-to-end
OAM pings will be conducted for every
defined PVC. The result of the pings will be
recorded in an array for later use to
determine the usability of the particular
PVC for connectivity. This list helps the
PVC to manage the available PVC for use,
and needs to be synchronised with
connections made without auto-sensing
PVC.
Once the connection is established, the
PVC is stored in flash as the default PVC.
Therefore upon reboot, this PVC is
automatically chosen as the PVC for that
connection.
The list of default PVCs and backup PVCs
need to be global for the management of all
connections, non auto-sensing PVC
connection and auto-sensing connections.
These lists allow end users to establish
connectivity without keeping track of the
PVC used.
