Interphase AdvancedMC Products Featured in MicroTCA Demonstration; T1/E1/J1 and Quad-Port Gigabit Ethernet mezzanines on display in Motorola Booth #48039 at SUPERCOMM 2005.

PLANO, Texas -- Interphase Corporation (Nasdaq:INPH), an international supplier of next-generation networking technologies, today announced its participation in the Motorola MicroTCA demonstration at SUPERCOMM 2005 (booth #48039) showcasing the SlotOptimizer(TM) 364G Quad-Port Gigabit Ethernet Interface and the iSPAN(R) 3639 T1/E1/J1 Communications Controller AdvancedMCs(TM) designed for both AdvancedTCA(TM) and emerging MicroTCA platforms. MicroTCA brings the reliability, manageability and performance advantages of ATCA in a cost effective and smaller form-factor platform solution. MicroTCA has been defined for use in a wide variety of applications where size and cost constraints preclude the use of large form-factor architectures.

Interphase designed its portfolio of AdvancedMC mezzanines for use in both AdvancedTCA and MicroTCA platforms. The primary benefit of MicroTCA is the ability to use AdvancedMC modules in a standard 19-inch shelf without the need for an ATCA or custom carrier, leading to a substantial reduction in size, cost and power consumption. MicroTCA is the perfect complement to AdvancedTCA; in that it incorporates the latest trends in high speed interconnect technologies, next generation processors and improved reliability, manageability and serviceability in a smaller form factor. This open architecture is targeted at small form-factor central office and outside plant applications including wireless base stations, Wi-Fi/Wi-Max radio boxes, next-generation digital loop carriers, optical ADMs, and Fiber to the Curb optical network units.

The Interphase SlotOptimizer 364G AMC Quad-Port Gigabit Ethernet Adapter is a single-width, full-height AMC with four front access copper 10/100/1000 Ethernet interfaces, and PCI Express x4 per the AMC.1 specification. Drivers are available for Linux(R) for both Intel(R) and PowerPCTM hosts. Future product options include a half-height face plate, fiber interfaces, and driver support for VxWorks(R).

The Interphase iSPAN 3639 AdvancedMC T1/E1/J1 Communications Controller is a single-width full-height card with four or eight RJ48 T1/E1/J1 connections that are individually software selectable. The product includes an on board Freescale(TM) MPC8560 (PowerQUICC III(TM)) processor and supports multiple network protocols and inter-working functions including Q.SAAL/GR-2878, SS7 MTP1 and MTP2, frame relay, HDLC, and ATM. In addition, the iSPAN 3639 is designed for easy integration with multiple third party higher layer stacks for the delivery of a variety of packet switched and circuit switched infrastructure elements.

"Interphase is very excited by the market opportunities that are opened up by MicroTCA for cost-effective, high-performance, small form-factor platform solutions," said Greg Kalush, President and Chief Executive Officer of Interphase Corporation. "MicroTCA enables Interphase to expand our portfolio of solutions and together with our strategic platform partners target applications where the larger CompactPCI(R) and AdvancedTCA form factors do not meet the form-fit requirements of our joint TEM customers."

"Interphase has demonstrated the ability to deliver leading-edge I/O modules that are easily integrated into our Open Application-Enabling Platforms, enabling our joint customers to bring new applications to market faster," said Wade Campbell, Strategic Marketing Director, Embedded Communications Computing, Motorola. "Customers will continue to see increased time-to-market advantage by using the same AdvancedMC module designs that are deployed as mezzanines on AdvancedTCA blades in new products based on the evolving MicroTCA standard."
