IRVINE, Calif.--(BUSINESS WIRE)--April 21, 2003

Toshiba America Information Systems, Inc., Network Products Division (TAIS NPD) today announced that it was awarded DOCSIS(R) 1.0 and DOCSIS(R) 2.0 certification status for its PCX2600 data-only cable modem, and DOCSIS 1.0 certification status for its PCX4500 Wireless Cable Modem Router in CableLabs(R) Certification Wave 25.

The PCX2600 introduces a deployable DOCSIS 2.0 certified modem from Toshiba that uses both advanced time division multiple access (A-TDMA) and synchronous code division multiple access (S-CDMA) protocols. The certified PCX4500 marks the beginning of Toshiba's expanded line of wireless cable modem routers.

Toshiba's DOCSIS 2.0-certified PCX2600 cable modem is the logical next step in DOCSIS 2.0 capabilities, building upon the A-TDMA support found in the company's PCX2500 model. It enables increased upstream throughput from the end user to the Internet, and provides the network operator the ability to offer symmetrical bi-directional data services. The PCX2600 Cable Modem will also provide easy backward compatibility with DOCSIS 1.0 and 1.1 standards. Toshiba expects cable operators to be able to create and support new services for both home and business use such as video conferencing and peer-to-peer applications with the new model.

"Although Toshiba has been producing cable modems with some DOCSIS 2.0 capabilities for a while now, the PCX2600 certification gives us the green light to start selling modems with both A-TDMA and S-CDMA protocols to MSOs that are currently laying the foundation for future DOCSIS 2.0 deployments," said Fred Berry, vice president, general manager of Toshiba America Information Systems, Inc., Network Products Division. "Toshiba is strongly committed to DOCSIS 2.0 standards and to developing innovative broadband access products that continue to help cable operators expand their services offerings."

Toshiba's PCX4500 Wireless Cable Modem Router unit includes a Toshiba cable modem, an 802.11b router for wireless networking and a Stateful Inspection firewall. The unit is CableHome-based, DOCSIS 2.0-ready and has single Ethernet and USB ports. The PCX4500 is Toshiba's second wireless cable modem router product. Toshiba's PCX5000 Wireless Cable Modem Router, which also offers the cable modem, 802.11b wireless router and Stateful Inspection firewall, as well as four 10/100 ports, began shipping in December 2002.

Toshiba NPD has a strong record of successful CableLabs certifications. In December 2002, Toshiba was the first major cable modem vendor to be awarded CableLabs PacketCable certification status for a Voice-over-Internet Protocol (VoIP)-enabled cable modem, the same modem awarded the first DOCSIS 1.1 certification of a multimedia terminal adapter (MTA). In 2001, Toshiba's PCX2500 DOCSIS cable modem earned the first DOCSIS 1.1 certification status for a production modem, and Toshiba was first to achieve EuroDOCSIS 1.1 certification as well.

Toshiba's line of PCX cable broadband devices is available through service provider partnerships, various national retail chains, and online at www.shoptoshiba.com.
