ABSTRACT:
A platform for connecting to a CCS7 network for supporting concurrently running CCS related applications. Copies of the SUs flowing through the network are sent to the platform where the FISUs, LSSUs and MSUs are filtered to provide the desired SU type for each of the applications. The MSUs are filtered by MSU category and MSU type within category into groups of MSUs of particular interest to the applications, respectively. Linked lists of filter elements associated with the respective linksets of the CCS7 network perform the filtering by comparing category and type fields to the MSU categories and types to form the groups. Filter change data received at a user interface is utilized to modify the filters.
