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).
