Interphase and Continuous Computing Demonstrate Advanced Wireless Applications on AdvancedTCA Platform

Pre-integrated Trillium+plus SS7 Signaling Demonstration at SUPERCOMM 2005

PLANO, TX - June 2, 2005 - Interphase Corporation (NASDAQ: INPH), an international supplier of next-generation networking technologies, today announced a live demonstration at SUPERCOMM 2005 featuring the Interphase iSPAN 4539F PMC T1/E1/J1 controller and iWARE SS7 software in Continuous Computing's Trillium+plus ISUP Network Service-Ready Platform. Trillium+plus ISUP is a pre-integrated signaling solution that enables rapid SS7 deployments in both AdvancedTCA and CompactPCI platforms. The demonstration will be hosted by Interphase in the PICMG pavilion (booth #43085CC) and by Continuous Computing (booth #32076) at SUPERCOMM 2005 in Chicago, Illinois from June 7-9.

Interphase and Continuous Computing have developed solutions for telecom equipment manufacturers (TEMs) to significantly reduce costs and development cycles required to integrate system components. The highly scalable Interphase iSPAN 4539F line card, which supports from two to 128 links in PMC or PCI form factors with rear and front access options, is an integral component of Continuous Computing's Trillium+plus demonstration. In addition to the line card, the Trillium+plus ISUP signaling solution is comprised of high-performance Trillium ISDN User Part (ISUP) binary code and integrated management software.

The demonstration at SUPERCOMM highlights two innovative features for mobile service providers. The Custom Ringback Tones service lets mobile subscribers replace the typical "ring" or "busy" tones an incoming caller hears when they dial a subscriber's number with a variety of music, such as the latest Top-40 song or a classic Frank Sinatra tune. The Missed Call Alerting application records all unsuccessful incoming calls when mobile users are outside the coverage area or a subscriber's phone is turned off. Once the phone is re-connected to the network, the application delivers a call summary via Short Message Service (SMS), providing the subscriber with caller information for missed calls such as call time, calling party name and calling party's phone number.

"Interphase and Continuous Computing share a commitment to supplying telecom equipment providers with cost-effective solutions and a faster time to market," said Linsey Miller, Director of Business Development at Interphase Corporation. "This demonstration symbolizes our partnership with Continuous Computing to enable the delivery of highly integrated, development-ready platform solutions to our TEM customer base for the rapid deployment of advanced wireline and mobile infrastructure solutions and applications."

"We are pleased to showcase the Interphase iSPAN 4539F SS7 line card and software in the Trillium+plus demonstration at SUPERCOMM, which illustrates how Continuous Computing enables TEMs to simplify and accelerate the deployment of SS7 network nodes," said Steve Kimball, Director of Business Development for Continuous Computing's Trillium business unit. "As one of our strategic partners, Interphase shares a mutual goal of delivering pre-integrated solutions to TEMs for accelerating time to market and reducing total life cycle costs."

The Trillium+plus pre-integrated SS7 signaling solution demonstration will be on display at SUPERCOMM, June 7-9, in Chicago, Illinois, in booth #43085CC and #32076.
