Networld+Interop 2001

POINTE CLAIRE, Quebec & LAS VEGAS--(BUSINESS WIRE)--May 8, 2001

N+I Show--RAD Data Communications, Inc., a leader in unique access solutions for carriers and enterprise networks, today announced continued leadership in TDMoIP (Time Division Multiplexing over Internet Protocol) technology. The company cited two new product enhancements in its IPmux line of TDMoIP gateways, as well as a new TDMoIP Alliance Program. This announcement was made at Networld + Interop 2001 in Las Vegas.

"Over the past year, TDMoIP has proven itself a superior alternative to VoIP for both enterprise networks and carriers," said Eitan Schwartz, vice president and general manager of TDMoIP technologies. "Organizations such as the Spokane School District are ripping out their VoIP systems and replacing them with TDMoIP solutions. Enterprises enjoy benefits such as investment protection and a simple migration path to IP, while carriers find value in new service revenues and low cost deployment."

Particularly noteworthy as a new product enhancement for 2001 is the IPmux-16 with T3/E3 interfaces. Previously only available with T1/E1 capabilities, the IPmux-16 is now capable of efficiently extending unframed T3 and E3 circuits transparently over packet networks - independently of the underlying transport infrastructure. Solution benefits include new service revenues, low cost deployment with quick installation, and reduced operational costs. The IPmux-16 with T3/E3 interfaces was announced today at N+I Las Vegas, and is scheduled to begin beta in June 2001.

Also scheduled to begin beta in the summer of 2001 is the IPmux-1E TDMoIP gateway. Like its sister product, the IPmux-1, the IPmux-1E is a compact and simple to install unit - ideal for customer premises. However, the IPmux-1E can aggregate analog or ISDN BRI voice with Ethernet user data over an Ethernet uplink, and also offers a redundant power supply.

In addition, RAD recently introduced the TDMoIP Alliance Partner (TAP) Program to promote an association of vendors offering complementary products and services relating to TDMoIP and RAD's IPmux product line. This Alliance Program aims to deliver comprehensive, interoperable solutions to the marketplace. Partner benefits include joint sales and marketing activities, the ability to offer more complete and unique solutions, and discounts on customer demo equipment.

"Gigabit Ethernet technology is leading edge, cost-effective and satisfies the needs of high bandwidth applications in such market segments as corporate campus, education, government, military, utility, and transit," said Marty Lattman, president of RAD Data Communications, Inc. "Additionally, service providers are latching onto Gigabit Ethernet as an alternative to ATM in metropolitan area networks. The addition of transparent T3/E3 and analog voice capabilities over IP, plus the establishment of our Alliance Program, is proof that RAD remains the leader in TDMoIP."

TDMoIP Background

RAD has pioneered the development of TDMoIP technology, which combines features from Time Division Multiplexing and IP to deliver synchronous T1/E1 and T3/E3 circuits transparently over IP networks. TDMoIP allows carriers and enterprises to migrate to IP-based infrastructures without discarding their investments in legacy PBX and TDM equipment. A more cost-effective alternative to VoIP, TDMoIP is simpler and uses less bandwidth. RAD implements TDMoIP in its IPmux line of TDMoIP gateways.
