Bearer.
Failure of VNS D-channel
If the D-channel is not operable, the VNS route list entry is chosen, and then
this entry is bypassed. In a network VNS environment, calls will remain
queued at the source node.
If the VNS D-channel fails when a call is established, the call remains
established. This is, however, without the ability to use the networking
features normally supported by the VNS feature.
Failure of Bearer
Failure of the VNS Bearer trunk results in the VNS call being cleared.
