Title: Multiline telephone including interacting call appearances
Inventor: AHUJA SUDHIR RAMAN
IPC: H04M3/56
Filed: 1999-09-01
Abstract: Interacting call appearances are realized by enabling voice input/output to be simultaneously available on any combination of call appearances at a given time on a given terminal. Consequently, a user may, for example, listen to the voice output of one or more call appearances that are active at the terminal at a given time.  Additionally, the user may direct voice input to one or more call appearances that are active at the terminal at a given time. Thus, the user, at any given time, may listen or speak to one or more parties on unrelated calls. Additionally, a user can employ more than one voice input/output device at his/her terminal. Specifically, the ability to simultaneously use more than one call appearance at a terminal at a given time is realized by separating call control from media routing and input/output control. Thus, the appearance of a call at a terminal is separated from the voice input/output that is required for the call. To this end, a user terminal or resources available to it must have the capability of mixing multiple channels of audio, as well as, the capability of multiplexing/demultiplexing voice inputs and outputs into and from line appearances.

Title: Method and apparatus utilizing ss7 signalling for establishing broadband connections
Inventor: MATTHEWS TERENCE H
IPC: H04Q3/00
Filed: 1999-09-24
Abstract: A system and method for tracking aspects of a broadband communications connection via SS7 protocols and systems in a narrowband network is disclosed. When a broadband connection is initiated, a narrowband call to an SS7 server is generated. The SS7 server queries the station at the originating point of the call for details about the requested broadband connection. Once answered, the SS7 server sends a proxy to the broadband server to establish a connection. A complementary proxy is generated at the destination point of the network. The broadband connection is established and the SS7 server maintains information about the broadband connection. Upon completion of the broadband connection, a termination signal is generated and sent through the broadband network. The broadband network then tears down the connection and the SS7 server sends the appropriate statistics about the broadband connection to the end office associated with the originating point of the communications.
