System and method for interfacing a local communication device
First Claim
1. A method of operating a communication system comprising:
- receiving GR-303 signaling into a signaling processing system;
in the signaling processing system, processing the GR-303 signaling to select an identifier for a header of a user communication, wherein the selected identifier is for routing the user communication in a packet format;
transferring a control message from the signaling processing system indicating the selected identifier;
receiving the control message into an interworking unit;
receiving the user communication in a GR-303 format into the interworking unit;
in the interworking unit, in response to the control message, converting the user communication from the GR-303 format into the packet format having the selected identifier in the header; and
transferring the user communication in the packet format having the identifier in the header from the interworking unit, wherein a packet system routes the user communication based on the identifier.

Abstract
A system to interworking a call between a plurality of networks having different formats. The system has a GR-303 system, an integrated services digital network system, a service platform, and an asynchronous transfer mode system. The system has a signaling processor that is adapted to receive the call signaling and to process the call signaling to select a connection to one of the GR-303 system, the integrated services digital network system, the service platform, or the asynchronous transfer mode system. The signaling processor thereby selects the corresponding system on the connection. The signaling processor transports a control message identifying the selected connection. An interworking unit receives the user communications and the control message. The interworking unit converts the user communications from the format in which it was received to the format that is compatible with the selected system. The user communications are then transported on the selected connection.

11. A communication system to handle a call from a caller, the method comprising:
-
a signaling processing system configured to receive and process GR-303 signaling to select an identifier for a header of a user communication and transfer a control message indicating the selected identifier, wherein the selected identifier is for routing the user communication in a packet format; and
an interworking unit configured to receive the control message, receive the user communication in an GR-303 format, convert the user communication from the GR-303 format into the packet format having the selected identifier in the header in response to the control message, and transfer the user communication in the packet format having the identifier in the header, wherein a packet system routes the user communication based on the identifier. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
