The url specifies a file location. The file contains
individual DNIS entries that belong to the DNIS map
name specified by cvDnisMappingName.
Once a url is created and associated with a map name (the
association is complete when the row is made active(1)),
it cannot be modified while cvDnisMappingStatus is
active. If a different url needs to be associated with
the current map name, the row status should be made
notInService(2) and this object has to be modified to
associate a new url. When a new association is made all
the DNIS entries corresponding to the old association
will be deleted from the cvDnisNodeTable.
The url is read when the row status is made active(1) or
when the row status is active and the object
cvDnisMappingRefresh is explicitly set to refresh(2).
If the url is not accessible then a
cvDnisMappingUrlInaccessible notification will be
generted.
