ATLANTA -- Firing a shot at Texas Instruments Inc. in the communications chip market, Intel Corp. here today re-launched a programmable digital signal processor (DSP) product that supports voice and data applications in carrier-class networks.
Using multiple, proprietary DSPs on the same device, the IXS1000 Media Signal Processor from Intel enables a system to support voice, data, fax and other capabilities over ATM or voice-over-Internet Protocol (IP) networks. The IXS1000 is being announced at the Supercomm trade show here today.
The IXS1000 is less expensive than traditional chips that are used for these functions, notably general-purpose DSPs from TI, according to a spokesman from Intel of Santa Clara, Calif. "We can provide the pieces for voice-over-IP at a lower cost than TI," the spokesman said.
Besides TI, Intel will also compete in the so-called voice-processor chip market against Broadcom, Centillium, PMC-Sierra, among others.
The Intel spokesman confirmed that the IXS1000 is a slightly different version of the so-called VX-SP1000 device, which was originally developed by VxTel Inc. of Fremont, Calif. In February, Intel acquired two-year-old VxTel for $550 million (see Feb. 26 story ).
VxTel actually rolled out the VX-SP1000 device last summer (see Aug. 31 story ). Originally, the VX-SP1000 was a two-chip solution. The new version is said to be a single-chip product, according to Intel.
Designed for Class 4 and 5 switches, gateways, and other products, the IXS1000 can process up to 240 uncompressed G.711 voice channels. Other key telephony features include comfort-noise generation, voice-activity detection, and tone detection and generation.
The chip consists of several components on the same device, including multiple DSPs, a central processor unit, SRAM, and I/O interfaces. The chip works in conjunction with the LXT3108, an 8-port T1/E1/J1 line-interface unit, and the IXF3208 8-port T1/E1/J1 framer.
The IXS1000 and the LXT3108 are priced at $467.00 and $61.58 each respectively in 1,000 unit quantities. Samples are now available. Prices for the IXF3208 were not given. It will be shipped later this year.
