Integrated Telecom Technology, Inc. and Harris & Jeffries, Inc. Announce Partnership.

CHICAGO--(BUSINESS WIRE)--March 31, 1998--

Seamless hardware and software subsystems will help equipment vendors speed development of ATM links in switched ethernet products

Integrated Telecom Technology, Inc. (IgT) and Harris & Jeffries, Inc. (H&J) announced today -- at the Embedded Systems Conference-Spring, here -- a joint development and co-marketing partnership that will help network equipment manufacturers to quickly address the explosive market opportunity of connecting local area networks to ultra-high speed global networks.

Under this agreement, IgT will develop a software interface which integrates several of H&J's popular Soft-ATM(tm) software subsystems for use with IgT's SESAR(tm) (switched ethernet segmentation-and-reassembly) processor and associated SESARSoft(tm); network-ready asynchronous transfer mode (ATM) and virtual local area network (VLAN) software. Seamless hardware and software subsystems can significantly reduce the development cycles for new networking products.

This integrated solution combines IgT's SESAR processor and SESARSoft software with H&J's Soft-ATM software to create a powerful standards-compliant switched ethernet-to-ATM solution. The solution can be used by network equipment manufacturers, OEMs and integrators to accelerate their time-to-market with lower-cost, high-performance network products. This solution is particularly relevant to developers of ethernet switches, edge switches, workgroup switches and related network equipment.

"Today, companies are faced with intense time-to-market and time-to-revenue pressures. They need to provide differentiated products, but those products must be standards-based. Often best-of-quality, standards-compliant components present the most effective way to shorten their development cycles," said Paul Zorfass, embedded analyst at International Data Corporation (IDC), a Massachusetts-based market research firm. "Communications protocols are difficult to develop, but every communications device requires them, so OEMs can benefit from a reliable source for their protocol libraries. With its strategy of being a quality supplier for these standards-based communications protocols Harris & Jeffries lets developers focus on differentiating their products," Mr. Zorfass continued.

IgT's SESAR processor provides a flexible, upgradeable solution for performing the ethernet switching and segmentation-and-reassembly (SAR) tasks required to communicate over an ATM network. The SESAR and SESARSoft packages represent a significant development effort and provide a considerable time-to-market advantage for network equipment manufacturers.

Reduces Development Time and Risk

SESARSoft includes the Base Package and the LAN/WAN Switching Package. The Base Package provides the device driver and other functions, while the Switching Package includes all of the components of the Base Package as well as control modules, interface modules and several management functions. The LAN/WAN Switching Package is being modified by IgT to allow customers to easily integrate Harris & Jeffries industry-leading Soft-ATM Software Subsystems including Soft-ATM UNI Signalling, LAN Emulation Client (LEC) and Interim Local Management Interface (ILMI) Software Subsystems. This integrated solution enables the LEC software to take full advantage of the underlying LAN Emulation (LANE) protocol support in the SESAR processor. The comprehensive offering provides a single solution that further reduces development time and risk and assures interoperability with virtually all emerging ethernet/ATM networking products.

"This new partnership benefits developers by shortening the time required to complete the porting and integration of ATM software with an operating system and SAR," said Ken Lee, president and CEO of IgT. "It also helps accelerate other development tasks, while optimizing developers' limited resources to allow them to focus on creating differentiated products," Mr. Lee continued.

"Each component has proven itself in hundreds of network equipment products so developers save not only time but reduce their risk," stated Ethan Harris, president of Harris & Jeffries, Inc. "Packaged solutions such as we are offering today represent one more important step in reducing the time, cost, complexity and risk in getting ATM network products into the modern telecommunications market," Harris noted.

Supports Most Popular RTOSs

SESARSoft and Soft-ATM software support most popular real-time operating systems (RTOS) including ISI's pSOS(R) and Wind River Systems' VxWorks(R). This solution set is highly portable and can be used on virtually any target system application.

Harris & Jeffries' Soft-ATM Signalling Software Subsystem is the industry's highest performing ATM signalling stack. In measured tests, the software has achieved a call setup rating in excess of 4800 calls-per-second (CPS). Soft-ATM subsystems are built upon H&J's software architecture which ensures backwards compatibility and lifecycle re-use. Soft-ATM also includes a powerful developer's toolkit and Harris & Jeffries' Interoperability Guarantee.

The SESAR processor is priced at $129 each in high volume purchases. SESARSoft pricing ranges from $25,000 to $75,000 per development license. Samples will be available for production evaluation in May, with production units available in June, 1998. SESAR and SESARSoft are available exclusively from IgT.

Pricing of Soft-ATM products ranges from $15,000 to $80,000 per product, per development license, depending on configuration purchased. Volume discounts may apply. Soft-ATM is available exclusively from Harris & Jeffries, Inc.
