20090059960 | VOICE AND DATA EXCHANGE OVER A PACKET BASED NETWORK WITH TIMING RECOVERY - 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. | 03-05-2009 |

20100020791 | Method and System for a Gigabit Ethernet IP Telephone Chip with No DSP Core, Which Uses a RISC Core With Instruction Extensions to Support Voice Processing - Methods and systems for processing data are disclosed and may comprise receiving packetized data comprising voice data and network data via an Ethernet switch integrated within a single gigabit Ethernet IP phone chip. The received packetized data may be processed via a single main processor core integrated within the single gigabit Ethernet IP phone chip. The single main processor core may comprise circuitry that is controlled by an instruction set for handling processing of the voice data for a plurality of voice channels without the use of a separate DSP. It may be determined whether data to be processed by the single main processor core is voice data or network data. If the data to be processed by the single main processor core is voice data, at least one modified instruction may be selected from the modified instruction set for processing the voice data. | 01-28-2010 |
20100142519 | METHOD AND SYSTEM FOR AN ETHERNET IP TELEPHONE CHIP - Methods and systems for an Ethernet IP phone chip are provided. In this regard, data may be received via a first port of an Ethernet switch in the Ethernet IP phone chip, and the port(s) via which the data is forwarded may be determined based on characteristics of the data. The Ethernet switch may receive data from a network via a first port, and communicate the received data to one or more on-chip interfaces via a second port. The on-chip interfaces may process the received data and may communicate video contained in the data to an off-chip video processing device. The Ethernet IP phone chip may receive video data from an off-chip video processing device via one or more on-chip interfaces, packetize the video data into one or more Ethernet packets; and communicate the packet(s) onto a network link via the Ethernet switch. | 06-10-2010 |
20110170544 | METHOD AND SYSTEM FOR A GIGABIT ETHERNET IP TELEPHONE CHIP WITH INTEGRATED SECURITY MODULE - A method for processing Ethernet data and may include receiving Ethernet data via at least one Ethernet physical interface transceiver (PHY) integrated within a single Ethernet IP telephone chip. At least one secure application key may be received from a secure server by an on-chip security module (OSM) integrated within the Ethernet IP telephone chip for processing the received Ethernet data. The Ethernet IP telephone chip may be authenticated prior to the processing of the received Ethernet data using a security processor integrated within the OSM. The received Ethernet data may be processed by the Ethernet IP telephone chip based on the received at least one secure application key. The at least one secure application key may be communicated only from the secure server to the Ethernet IP telephone chip. The received Ethernet data may include one or both of video data and/or voice data. | 07-14-2011 |
