Ergonomics is easy to describe and hard to satisfy,” said Artigliere. You want something with the intuitive operation of eyeglasses, with no instructions required: You put them on and you take them off. You also have to have enough resolution and colors and be able to handle video signals in a way that's pleasant to the viewer.

Claiming to now offer a fully rounded VoIP portfolio, Intel Corp. has launched the IXS1000 Media Signal Processor (MSP) with a comprehensive software suite, an eight-port T1/E1/J1 line interface unit, and an eight-port T1/E1/J1 framer, all of which, the Santa Clara, Calif., company says, can power network systems able to process more than 2,000 simultaneous voice connections on one VoIP line card.

Integrated Device Technology Inc., Santa Clara, said it has developed an octal codec capable of processing eight individual analog voice channels for VoIP, as well as voice routers, gateways, multiservice access switches, residential integrated access devices, and digital loop carrier voice switches.

Intel's position in VoIP was secured by its acquisition earlier this year of VxTel. [That acquisition] provided us with new DSP capabilities for VoIP building blocks designed to support multiple services and protocols with flexible software and highly integrated silicon,” said Tom Franz, vice president and general manager of the Intel Access and Switching Group.

Intel said its VoIP line is designed for T1/E1/J1 connections ranging from the Public Switched Telephone Network to packet-based networks, including Gigabit Ethernet and IP networks. The Intel IXS1000 MSP is based on a DSP architecture specifically designed for carrier-grade voice, fax, and data processing applications, according to the company.

Intel's LXT3108 eight-port T1/E1/J1 short- and long-haul line interface unit and its IXF3208 eight-port T1/E1/J1 framer feature a switching capability that the company claims addresses network redundancy without mechanical relays, and software that allows automatic signal-pulse matching rather than having to change resistors and capacitors on a line card manually.

The IXS1000 and the LXT3108 are available in sample quantities and are priced at $467 and $61.58, respectively, in 1,000s. Intel said its IXF3208 will sample by the end of the year, but the company did not disclose pricing.

IDT says its new octal codec provides greater density than competing devices through its higher channel count, while offering OEMs design flexibility with its built-in, programmable feature set.

Our new codecs address the convergence of voice and data by assisting our customers to more quickly integrate voice-oriented services and capabilities,” said Mario Montana, director of IDT's telecommunications products division.

IDT's codec offers AC impedance matching, tone generation, frequency response correction, gain setting, and selectable microprocessor interface/general communications interface.

Comments made after the panel discussion became even more pointed. Even the primary backers of OpenAccess appeared disappointed with Cadence's response, including Greg Spirakis, vice president of the architecture group at Intel Corp., who has been actingas the group's most visible spokesman.

'Inconvenient' delay

The lack of a time line for source code release is definitely inconvenient,” Spirakis said. It leaves the impression Cadence is not as forthcoming as they could be. From our experience Cadence has been very open with us, but we understand it might appear differently to the vendor community. In the long run it's important all vendors participate — otherwise we don't have a usable standard.”

The availability of source code will be very important long term,” said John Darringer, manager of system-level design at IBM Research. What we're saying now is let's get going, let's work with Cadence on this thing, and I'm confident we'll be able to work it out.”

The API and the binary developer's kit should be enough to get EDA vendors started with compliance to OpenAccess, said Andy Graham, Si2 president. But the question of [open] control will not be confirmed until the source code is available,” he acknowledged.
