  • System and method for implementing user-to-user information transfer services
    Patent number: 6807170
    Abstract: A system and method for implementing user-to-user information transfer services over a communications network having switches, a voice network, and a signaling network. The invention establishes a connection path over both the voice network and the signaling network for connections requested by users to follow such that multiple connections may utilize the same connection paths. Each of switches have available a database for tracking and maintaining current connection information for connections with other switches.

  • System and method for implementing user-to-user data transfer services
    Patent number: 6195347
    Abstract: A system and method for implementing user-to-user data transfer services utilizes an overlay network to transfer user-to-user data between users independent of communications between the users on a conventional signaling network. The system and method examines a frame of data received from a user to determine whether the frame contains user-to-user data. If the frame does contain user-to-user data, the user-to-user data is removed from the frame and formatted for transfer. The formatted user-to-user data is then transferred to the recipient via the overlay network, independently of the communication between the users on the signaling network.

  • Method of and system for terminating calls to selected trunk group members
    Patent number: 6058176
    Abstract: A method of and system for providing selective trunk group member termination service in a network of telecommunications switches. Each trunk group at a terminating switch that requires selective trunk member termination is identified by a terminating member trunk group parameter. A data access point (DAP) that is accessible by the switches of the network to provide call routing and number translation services identifies a set of trunk group members selected for selective trunk group member termination by means of a trunk group member range parameter. When a call is received at an originating switch of the network, the originating switch queries the DAP and the DAP returns call routing information. If the call requires selective trunk member termination, the call routing information includes the trunk group member range parameter.
