DiFC Usage

In contrast to SiFCs, the Oracle Communications Unified Session Manager fires DiFCs within the context of a session. During the session, the Oracle Communications Unified Session Manager associates the iFCs within the DiFC file with the user, as needed. DiFC usage is invoked during session initiation.

Note that DiFCs are database agnostic. You can use DiFCs for HSS, ENUM and local database configurations. An operational overview of SiFCs and DiFCs is shown below.
