Patent number: 8588073Abstract: A voice queue includes a primary queue and a secondary queue. The secondary queue is operable to store voice packets and generate timestamps for the voice packets. The primary queue is operable to receive the voice packets from the secondary queue, store the timestamps for the voice packets, and store sequence numbers for the voice packets.Type: GrantFiled: May 9, 2012Date of Patent: November 19, 2013Assignee: Broadcom CorporationInventors: Henry Li, David M. Enns, Jordan J. Nicol, Kenny C. Kwan, Ross Mitchell, Wilf LeBlanc, Ken Unger, John Payton, Shawn Stevenson, Bill Boora, Onur Tackin

Publication number: 20120236845Abstract: A signal processing system which discriminates between voice signals and data signals modulated by a voiceband carrier. The signal processing system includes a voice exchange, a data exchange and a call discriminator. The voice exchange is capable of exchanging voice signals between a switched circuit network and a packet based network. The signal processing system also includes a data exchange capable of exchanging data signals modulated by a voiceband carrier on the switched circuit network with unmodulated data signal packets on the packet based network. The data exchange is performed by demodulating data signals from the switched circuit network for transmission on the packet based network, and modulating data signal packets from the packet based network for transmission on the switched circuit network. The call discriminator is used to selectively enable the voice exchange and data exchange.Type: ApplicationFiled: May 9, 2012Publication date: September 20, 2012Applicant: BROADCOM CORPORATIONInventors: Henry Li, David M.
