Controller based call control for atm svc signaling

Abstract

A method for controlling circuit switched communications using switched virtual circuit (SVC) signaling includes receiving, at a service controller over a signaling channel from an originating end system, a connection setup signal requesting a switched virtual circuit connection. A proxy setup signal enabling setup of the switched virtual circuit connection in response to the connection setup signal is sent over a proxy signaling channel separate from the signaling channel.
