Patent number: 6501759Abstract: The invention is a system for providing virtual connections through an ATM interworking multiplexer on a call-by-call basis. A signaling processor receives signaling for a call and selects the virtual connection for the call. The signaling processor generates control messages that identify the selection and transfers the control messages to the ATM interworking multiplexer that accepted the access connection for the call. The multiplexer converts user information from the access connection into ATM cells for transmission over the virtual connection in accord with the control messages.Type: GrantFiled: February 4, 2000Date of Patent: December 31, 2002Assignee: Sprint Communications Company L.P.Inventors: Joseph Michael Christie, Michael Joseph Gardner, Albert Daniel DuRee, William Lyle Wiley

Patent number: 6470018Abstract: A system and method connects a call in a broadband system using the asynchronous transfer mode protocol for switching. Calls are connected over a SONET ring that has SONET multiplexers coupled by SONET paths. The SONET multiplexers are adapted to add calls to, and drop calls from, the SONET ring. An ATM cross connect system that has ATM cross connect devices is coupled to the SONET ring. The ATM cross connect devices provide provisioned ATM connections over the SONET ring. ATM interworking units are coupled to the ATM cross connect system. The ATM interworking units interwork calls with selected ATM connections in response to control messages. The selected ATM connections are provisioned between the ATM interworking units by the ATM cross connect system over the SONET ring. A signaling processor system receives call signaling for the calls, processes the call signaling to select the ATM connections for the calls, and sends the control messages to the selected ATM interworking units.Type: GrantFiled: August 21, 2000Date of Patent: October 22, 2002Assignee: Sprint Communications Company L.P.Inventors: William Lyle Wiley, Michael Joseph Gardner, Tracy Lee Nelson, Royal Dean Howell, Albert Daniel DuRee

Publication number: 20020031145Abstract: The present invention is an apparatus, system, and method for converting point codes in a signal transfer point in a telecommunications signaling system. The STP converts point codes which designate the origination and destination signaling points for the message. The conversion is based on information defined by the messages, such as origination or destination information. The present invention creates a virtual signaling system which can be reconfigured at the STP by converting point codes, and thus, altering the identities of the signaling points. The present invention is also operable to convert circuit identification codes and transfer integrated services user part messages to a user part.Type: ApplicationFiled: September 4, 2001Publication date: March 14, 2002Inventors: Joseph Michael Christie, Albert Daniel Duree, Michael Joseph Gardner, William Lyle Wiley

Patent number: 6351521Abstract: The invention is a test system that gives the user a single point of control to generate calls and run tests on a switching system for use in a communications network. The test system is capable of generating calls through a tandem switching system without using a local access switch. The test system is operationally coupled to the switching system by a signaling link and a call connection. The test system receives a first user request to generate a call. The test system transfers signaling to the switching system over the signaling link to cause the switching system to extend the call connection. The test system receives a second user request to run a test, and applies the test to the call connection. In some embodiments, the test system includes a web server that interfaces with a web browser operated by the user. The web server transfers information for screen displays to the web browser. The web server collects user requests from the web browser to generate calls and run tests.Type: GrantFiled: September 19, 2000Date of Patent: February 26, 2002Assignee: Sprint Communications Company L.P.Inventors: Albert Daniel DuRee, William Lyle Wiley

Patent number: 6178170Abstract: A system and method for transporting a call having call signaling and voiceband user communications through an asynchronous transfer mode system identifies when compression, encryption, or another processing option has been applied to the voiceband user communications. A first signaling processor processes the call signaling to identify a selected first connection and a processing option, such as a compression method, to be applied to the voiceband user communications. The first signaling processor transports a control message to a first interworking unit identifying the selected connection and the selected compression method. The first interworking unit compresses the voiceband user communications with the selected compression method, sets a convergence sublayer indicator bit as an indicator in an asynchronous transfer mode cell, fills the cell with the compressed voiceband user communications, and transports the cell over the selected connection.Type: GrantFiled: May 13, 1997Date of Patent: January 23, 2001Assignee: Sprint Communications Company, L.

Patent number: 6147994Abstract: The invention is a system and method for processing connections. Connection identifiers are assigned to indexes and stored in corresponding index latches. When communications arrive over a particular connection, the identifier for the particular connection is provided to all of the index latches. The index latch that stores a matching connection identifier provides its associated index. The index can be used to access a memory location that houses a processing instruction for the particular connection. The invention can be used within ATM multiplexers and gateways to facilitate connection processing.Type: GrantFiled: July 17, 1998Date of Patent: November 14, 2000Assignee: Sprint Communications Company, L.P.Inventors: Albert Daniel Duree, Tracy Lee Nelson, Michael Joseph Gardner
