This object specifies a DCCA client to use to communicate
with a DCCA server in a GGSN charging profile.
The profile name is the DCCA profile name
(cGgsnSADccaProfileName) which is present in
CISCO-GGSN-SERVICE-AWARE-MIB and it's outside the scope of
this MIB.
The presence of the object in this table indicates online
billing is required. Therefore, regardless of whether a
subscriber is prepaid or postpaid, the GGSN will contact
the DCCA server if this object is set.
If the user is to be treated as a postpaid user, the server
returns X and the user is treated as a postpaid user. If
this object is not set to valid value, then users using the
charging profile will be treated as postpaid (offline
billing).
