Method and system for processing outbound service calls via a network adjunct platform

Abstract

A method and system for processing a variety of outbound service calls initiated by a network adjunct platform (NAP) over a Small Scale Adjunct Primary Rate Interface (SSA PRI) in a telecommunications network on a call by call basis is disclosed. A outbound service subscriber triggers the NAP to initiate the desired outbound service call. The outbound service call may include, for example, a software defined network call (SDN), an AT&T Digital Link (ADL) call, or a Megacom call or other such suitable outbound service call. The NAP forwards set-up data based on the type of call desired to an originating toll switch (OTS) programmed to accept the set-up data from the NAP. After receipt of the set-up data, the OTS determines if the forwarded set-up data classifies the call as an outbound service call. If the forwarded set-up data contains outbound service parameters, the originating toll switch processes and routes the call initiated by the NAP as the appropriate outbound service call. The outbound service calls may include a local call, a long distance call or an international. The originating toll switch is also able to process and route non-outbound service or regular calls utilizing the same SSA PRI used for the appropriate outbound service calls. The need for separate dedicated trunk groups for each type of outbound service and for each subscriber of such service may be alleviated.
