Communication interface system

摘要

A communications interface system receives an initial address message for a call into a circuit process and transferring the initial address message to a call process. The call process processes the initial address message to generate and transfer set-up information to a bearer system. The bearer system receives user communications for the call and routes the user communications in response to the set-up information. The circuit process receives a release message for a call and transfers the release message to the call process. The call process processes the release message to generate and transfer tear-down information and a disconnect message. The circuit process generates and transfers a release complete message in response to the disconnect message. The bearer system terminates the routing of the user communications in the in response to the tear-down information.
