That is one of headline conclusions of Gemalto’s internal investigations into last week’s allegations, as reported in sister publication that the U.S. National Security Agency (NSA) and the British Government Communications Headquarters (GCHQ) allegedly stole encryption keys from the world’s largest maker of SIM cards for mobiles and bank cards, which enabled the spies to eavesdrop on billions of phone calls and texts around the world.

Meanwhile, wireless systems supplier Symbol Technologies in Holtsville, N.Y., has also filed a civil case against Proxim after being sued by the Sunnyvale company. Symbol has teamed up with chip supplier Intersil Corp. to fight Proxim (see May 14 story).

Based upon initial review of the two suits filed by Agere and Symbol, officials at Proxim said they believe the claims have no merit.

ATLANTA — Drawing on the digital signal processing capabilities of recently acquired VxTel Corp., Intel Corp. on Tuesday (June 5) announced a set of chips targeted at the voice gateways that bridge the telephone network with data networks.

The IXS1000 Media Signaling Processor, announced at the Supercomm trade show here, concentrates the DSP functions that form the heart of a voice gateway. Target customers for the chip are systems OEMs such as CopperCom Inc. or Jetstream Communications Inc., Intel said.

The IXS1000 is better groomed for voice processing than standard DSPs, said Randy Smith, senior product marketing manager for the edge access division of Intel. The device includes four DSPs dedicated to voice processing, which help it maintain wire-speed processing, Smith said. A general-purpose processor handles control functions such as call setup, allowing the IXS' card to operate without having to steal bandwidth from a host processor.

The added processing power allows the chip to create 50 calls per second, compared with roughly 1 call per second for general-purpose DSPs, Smith said. Calls can be groomed at the DS0 (64-kbit/second) level of individual phone lines.

Each IXS1000 can handle up to 240 calls simultaneously, Smith said. At Supercomm, Intel was showing reference cards built with the new chips and handling OC-3 (155-Mbit/s) or DS3 (45-Mbit/s) speeds.

Intel also announced two physical-layer parts also targeted for voice gateways: the LXT3108 line interface unit and the IXF3208 framer. Both are eight-port devices for T1, E1 or J1 connections. In addition to announcing the chips, Intel is producing gateway reference designs for use with the company's IXP1200 network processor.

The IXS1000 and the LXT3108 are sampling now for $467 and $61.58, respectively, in 1,000-unit quantities. The IXF3208 is due to begin sampling later this year.

Taiwan's motherboard industry is hopeful that sales of both Intel and AMD chips will spur business and help erase a slowdown in the PC sector, which Shih said has begun afflicting Asustek only in the past few months.

In the first quarter, when the overall PC market slumped, Asustek board shipments were [still] very good,” he said. Our 1.6 million units shipped in March actually was a record high for us.”

Shih said printed-circuit-board shipments for the first part of June are showing signs of recovering, although the company's sales to China, hailed as a region with high growth, have slipped in the past two weeks.

Nvidia enters chipset market

Meanwhile, Jeff Fisher, vice president of worldwide sales at Nvidia, Santa Clara, Calif., claimed the nForce has the fastest I/O south bridge in the industry and will be available this summer. Desktop boards with the chipset and GeForce 2 graphics card will ship in the fall.
