  • Patent number: 7283517
    Abstract: A multi-media terminal adapter couples to a network access module over a communication link. The network access module communicates IP frames over a frame switched network. The multi-media terminal adapter comprises a wide area network interface coupled to the communication link for exchanging IP frames with the access module and a local area network interface for receiving outbound data client IP frames from each of a plurality of data clients. Each outbound data client IP frame comprises a socket information that includes a local area network IP address and a data client port number. A VoIP module generates outbound VoIP frames. Each outbound VoIP frame comprises socket information that includes a VoIP port number selected from a first group of port numbers exclusively reserved for use by the VoIP module. A router module is coupled between the wide area network interface and each of the VoIP module and the local area network interface.

  • Publication number: 20050117605
    Abstract: A gateway comprises a router module coupled between a local area network interface and a wide area network interface. The router module receives an outbound IP frame from the local area network interface and provides a corresponding translated outbound IP frame to the wide area network interface. The router module comprises a transport layer translation module for performing network address and port translation on an IP header of the outbound IP frame. The router module further comprises an application layer translation module for detecting the presence of media session signaling information within payload of the outbound IP frame and performing network address translation and port translation of source network address information identified in the media session signaling information.
