A system allows switch signaling to be processed in a controller adjunct to a switch, and for the controller to effect the connection by signaling to the switch. This is accomplished by an end unit communicating service information to a controller and the controller instructing the switch to carry out the service transaction. The service information from the end unit is routed through the switch being controlled by the controller.

A network node sets up a virtual connection in a network based on a virtual connection request initiated from an access port different from a first location previously associated with an account of a user. The network node includes a receiver for receiving a signaling message from the access port requesting the virtual connection. The signaling message has at least one field modified to include an address of the access port. The network node further includes a profile database and a registration server. The profile database stores a service policy associated with the user account. The registration server stores an address of the first location associated with the user account as a default registration, determines whether the user is authorized to establish the virtual connection based on the service policy, and replaces the first location address with the access port address when the user is authorized.

A data messaging system includes a first Internet Protocol (IP) switch that includes a processor. The data messaging system also includes a first gateserver coupled to the first IP switch and coupled to a second IP switch. The data messaging system includes a second gateserver that is coupled to the first IP switch and to the second IP switch. The data messaging system further includes a first gatekeeper coupled to the first IP switch. The first gatekeeper is adapted to detect a failure of the first gateserver and to route data to the second gateserver in response to detecting the failure.

A method and system for associating a switched virtual circuit (SVC) connection request from an access port in an asynchronous transfer mode (ATM) network to a subscriber and optionally registering an address of the access port in relation to the subscriber. The method and system include receiving a signaling protocol message requesting the SVC connection from the access port, determining whether the signaling protocol message contains subscriber authentication data and, when authenticated, establishing the SVC connection. Furthermore, the SVC connection may be established only if service policies corresponding to the subscriber retrieved from a database indicate that the subscriber is entitled to make SVC connections. The method and system further include registering an address of the access port in the ATM network by substituting the address of the access port for an original subscriber address.

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.
