Patent number: 6272142Abstract: The invention is a tandem system for providing a tandem connection for circuit-based traffic. This tandem system comprises an ATM cross-connect, ATM interworking multiplexers, and a signaling processor. The multiplexer converts the traffic received by the tandem system into ATM where it is routed through the cross-connect and re-converted back into the circuit-based format at an ATM interworking multiplexer. The signaling processor controls the virtual connections and out going circuit-based connections used by the multiplexers.Type: GrantFiled: March 19, 1999Date of Patent: August 7, 2001Assignee: Sprint Communications Co.

Patent number: 6249529Abstract: 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: GrantFiled: July 16, 1998Date of Patent: June 19, 2001Assignee: Sprint Communications Company, L.P.Inventors: Jospeh Michael Christie, Albert Daniel Duree, Michael Joseph Gardner, William Lyle Wiley

Patent number: 6181703Abstract: The invention includes a system for processing telecommunications signaling. Signaling for a call is received into a signaling processor. The signaling processor processes the call and generates new signaling incorporating the processing. The new signaling is transferred to network elements as appropriate. The signaling processor is not coupled to a switch matrix and only communicates with the network elements over signaling links.Type: GrantFiled: September 8, 1995Date of Patent: January 30, 2001Assignee: Sprint Communications Company L.

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: 6081529Abstract: The invention is an ATM transport system that transports user information from a continuous signal transport system. The ATM transport system uses telecommunications signaling associated with the continuous signals to determine if the continuous signals are transporting any user information. If so, ATM cells containing user information are generated and transmitted, but if not ATM cells are not generated and transmitted. The invention includes an ATM interworking multiplexer and in some embodiments, a processor.Type: GrantFiled: September 18, 1997Date of Patent: June 27, 2000Assignee: Sprint Communications Company, L.
