*** THIS TABLE CURRENTLY NOT IMPLEMENTED ***
This attribute indicates the throughput link group, or groups, that
are being used to reach a neighbor which is either the next hop in
the path to the Call Server Resource Module (CSRM) supporting
the server. DPN server traffic will be load shared across the links, in
up to two link groups, when available. The link groups selected are
those associated with the two loop-free paths with the lowest
throughput metrics to the destination.
The link group can be that of either a Passport node interconnection
or a gateway to the CSRM.
If no link groups are listed then the server is not reachable in the
throughput class of service.
Link group instances are managed by the TransportResource
component. Further information about the links in the group can be
obtained from it.
