Harris & Jeffries announces newest version of its Soft-ATM Signalling Software Subsystem.DEDHAM, Mass.--(BUSINESS WIRE)--Nov. 4, 1996-- Introduces ATM Forum's UNI 4.0 and ITU-T See ITU. ITU-T - International Telecommunications Union compliant software; guarantees interoperability Harris & Jeffries Inc. (H&J), announced today the release of a new UNI 4.0 compliant Soft-ATM Signalling Software Subsystem (SSS SSS abbr. sick sinus syndrome ). The new software subsystem is used by network equipment manufacturers to add reliable, advanced signalling functionality to network devices. The Soft-ATM family of products provides manufacturers with a wide variety of networking source code components that allow them to develop very advanced ATM products cost effectively, while improving overall product performance and dramatically improving product time-to-market. Soft-ATM SSS is designed and developed, using UNI and NNI protocols, to provide the highest switched virtual circuit See SVC. switched virtual circuit - virtual circuit (SVC (1) (Switched Virtual Circuit) A network connection that is established at the time the transmission is required and disconnected when the session is completed. ) calls-per-second rate in the industry. Other products in the industry have been designed around the older and inefficient broadband ISDN (B-ISDN (Broadband-ISDN) A framework for advanced telecommunications from the ITU. Introduced in 1988 as an extension to ISDN, it was designed to provide a blueprint to integrate data, voice and video in the 21st century. ) standards, which can not achieve the significantly higher performance and throughput levels of Soft-ATM SSS. The highly compact source code is designed to require no more than 156K of memory in target systems. Different signalling options can be compiled out to minimize the size of target system memory. The new Soft-ATM subsystem release provides support for both user and network side UNI 3.0, 3.1 and 4.0, IISP IISP Information Infrastructure Standards Panel (ANSI) IISP Interim Interswitch Signaling Protocol IISP Institute of Information Security Professionals IISP International Institute for Software Process (Interim Interswitch Signalling Protocol) and PNNI (Private Network-to-Network Interface) A routing protocol used between ATM switches in an ATM network. It lets the switches inform each other about network topology so they can make appropriate forwarding decisions. (Private Network-to-Network Interface) signalling. The company said the new package also includes support for UNI 4.0 Available Bit Rate (ABR (1) (AutoBaud Rate detect) The analysis of the first characters of a message to determine its transmission speed and number of start and stop bits. (2) (Available Bit R ), Leaf Initiated Join (LIJ), Anycast Group Address, Proxy Signalling, and supplementary services. "UNI 4.0 signalling is important because it enables the use of ABR and other important features and because it provides the signalling framework for emerging standards such as LAN Emulation V2.0, MPOA and Voice/Telephony Over ATM (VTOA)," said Ethan Harris, president of Harris & Jeffries. The Soft-ATM signalling subsystem is flexible so that different signalling types -- UNI 3.0, 3.1, 4.0, IISP and PNNI -- can be selected at run time to run over different interfaces. This is important to ensure that products built using Soft-ATM will be compatible with other ATM devices, regardless of the type of signalling used. The new Soft-ATM subsystem, like all H&J source code packages, includes H&J's Interoperability Guarantee which guarantees that products developed using H&J source code will interoperate with any other device that also complies with the ATM Forum standards. The software packages include diagnostic traces, probes, loopbacks, and test applications that assist developers in performing a fast, easy, and hassle-free integration. Soft-ATM signalling is compatible and pre-integrated with H&J's entire Soft-ATM product line. Other Soft-ATM subsystems currently available include: ILMI, IP, over ATM, LAN Emulation Client, LAN Emulation Server (LES, BUS, LECS) Frame Relay to ATM Network Interworking (standard) interworking - Systems or components, possibly from different origins, working together to perform some task. Interworking depends crucially on standards to define the interfaces between the components. (FRF FRF The ISO 4217 currency code for the French Franc. .5) and Frame Relay to ATM Service Interworking (FRF.8). The company's products also include High-Performance Frame Relay, X.25 and PAD, SDLC and LLC software packages. Pricing and Availability The company said Soft-ATM Signalling Software Subsystem with UNI 4.0 compliance will be available in December. A subsequent release with ITU-T compliance is scheduled for the first quarter of 1997. All H&J customers under warranty will receive the update at no additional cost. Pricing of each Soft-ATM subsystem ranges from $15,000 to $80,000 per development license depending on configuration.
