Interphase Showcases Controllers at Smart Networks Developer Forum

4/29/2004 - Interphase Corporation (NASDAQ: INPH), an international supplier of next-generation networking technologies, is demonstrating the newest generation of its iSPAN® line of communications I/O solutions this week at the Motorola Smart Networks Developer Forum (SNDF) 2004 in Dallas, Texas. Based on the new Motorola PowerQUICC IITM MPC8264 Communications Processor, the iSPAN products will be demonstrating simulated telecom carrier applications including ATM AAL5 data processing and broadband SS7/high speed links (HSL) signal processing.

iSPAN products available with the 300 MHz MPC8264 processor include several of the Interphase T1/E1/J1 communications controllers including the iSPAN 6535 controller based on the standard CompactPCI® architecture, the iSPAN 4538/4539/4539F controllers based on the standard PMC architecture, the iSPAN 5539F controllers based on the standard PCI architecture, and the iSPAN 1635 controller based on the PICMG® 2.16 CompactPCI Packet Switching Backplane (CPSB) architecture. Additionally, the Interphase iSPAN 4532 PMC ATM over OC-3/STM-1 Communications Controller is based on a similar 300 MHz PowerQUICC II processor, the MPC8260A, which is more suitable for OC-3/STM-1 traffic processing. All of these products are intelligent communications controllers enabling high speed communications traffic processing and transport in telco carrier network applications such as those in second and third generation wireless networks, broadband access networks, and the new generation of the public telephone network. Use of the new Motorola MPC8264 chipset on the iSPAN controllers further enhances their line processing power and functionality, providing Interphase OEM customers with improved system performance by offloading system host CPUs of the compute-intensive communications processing required by today’s advanced services to end users. Such services enabled by these technologies include wireless text/picture messaging, Voice over Internet Protocol (VoIP), and broadband Internet access.

This week at the Motorola SNDF technology lab, which is open to all participants, Interphase will be demonstrating the iSPAN 6535 CompactPCI T1/E1/J1 Communications Controller processing broadband SS7 High Speed Links (HSL) traffic from multiple interfaces and also the iSPAN 4539 PMC T1/E1/J1 Communications Controller processing ATM AAL5 data traffic from multiple interfaces. Other telecom protocols supported by this generation of iSPAN products include ATM AAL2 for voice communications, traditional narrowband SS7 (Low Speed Links (LSL)) for signaling applications, Frame Relay for wide area voice and data applications, and Q.SAAL, which enables SS7 over ATM networks for advanced signaling applications.

“We were very early to market with this new generation of our iSPAN product line and we’re very pleased to be showcasing the products at Motorola’s Smart Networks Developer Forum,” said Randall McComas, Vice President of Sales and Marketing at Interphase Corporation. “These boards give our customers additional processing horsepower and computing functionality over our prior generation of PowerQUICC II-based products, and these new designs have been well-received by our customers since their initial release.”

Interphase will be in booth #120 at the Motorola Smart Networks Developer Forum from April 26 – April 29 at the Hyatt Regency Hotel at the Reunion Tower in Dallas.
