SBE Announces High-Performance SunLink-Compatible X.25 Solution for Sun Sparc Systems.SAN RAMON, Calif.--(BUSINESS WIRE)--Sept. 1, 1995--SBE(TM), Inc. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on : SBEI) today announced that its highly successful VCOM-54 multi-channel VMEbus communications controller is now available for use with the SunLink(TM) X.25, 8.0 software in Solaris(TM) environments, making it ideal for original equipment manufacturers and system integrators needing high-performance X.25 communications capabilities. Compared to the HSI (Hue Saturation Intensity) A color space similar to HSB. See HSB. controller, the SBE SBE - Microsoft Office Small Business Edition VCOM-54 provides eight ports instead of only four. Performance is also improved, due to less SPARC (Scalable Performance ARChitecture) A family of RISC CPUs from Sun that runs mostly under Sun's Solaris, but also under Linux and BSD operating systems. After development began in the mid-1980s by David Patterson of the University of California at Berkeley and Bill Processor intervention required to process incoming frames. In addition, the HSI card requires a clumsy external interface box, while the VCOM-54 provides direct I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output for RS-232, X.21, and V.35 from either the VME (Virtual Machine Environment) An operating system from Fujitsu Services (formerly ICL) that runs on its Series 39 mainframes. Introduced in 1975, VME is a comprehensive product that provides a variety of utilities for datacenter operations. front panel or from the VMEbus P2 connector. "In a direct response to overwhelming customer demands, SBE has developed a new high-speed STREAMS-based software driver for use in Sun Solaris 2.X environments that seamlessly marries the SunLink X.25 HDLC (High-level Data Link Control) A data link protocol from ISO for point-to-point communications over serial links. Derived from IBM's SDLC protocol, HDLC has been the basis for numerous protocols including X.25, ISDN, T1, SS7, GSM, CDPD, PPP and others. (LAP-B LAP-B Link Access Protocol-Balanced ) layer to the WAN (frame) layer of the VCOM-54 multi-channel communications controller," said Bill Allen, vice president sales and board products marketing at SBE. "This combination provides a cost-effective, high-performance frame-layer engine for VMEbus-based SPARC systems running SunLink X.25. As a result, the more flexible and higher-performance VCOM-54 may be readily used as a direct replacement for the Sun HSI(TM) communications controller in VMEbus-based applications," Allen added. Based on SBE's highly-acclaimed Shared Memory Queue (SMQ SMQ Sunday Morning Quarterback SMQ Surface Mount Quality (DKL Metals Ltd E-Qual) SMQ Standardised MedDRA Query SMQ Statement of Minimum Qualification SMQ String Missing Quote SMQ Split Matrix Quantization ) software interface, the SBE SunLink driver's modular and compact design permits the efficient sending and receiving of control and data messages between communication protocol layers. In the SunLink X.25, 8.0 implementation, the SMQ interface manages the exchange of data between the host processor(s) and the VCOM-54 controller(s) through the use of STREAMS messages. The SBE SunLink driver is also multi-threaded, supporting Solaris Multi-processor environments. The VCOM-54 multi-channel communications controller easily manages all frame level transport, including frame interrupt handling, DMA buffer management, and frame check sum error detection. This significantly increases the available host CPU's bandwidth for application specific tasks, resulting in greater overall system performance. The VCOM-54 multi-channel VMEbus communications controller is priced at $350 and available for immediate delivery. SBE, Inc. based in San Ramon, Calif., is a leading designer and manufacturer of VME and PC bus-based communications boards, as well as remote internetworking devices. These products are sold worldwide through OEM and distribution channels. SBE's mission is to provide cost effective "personal networking" solutions that simplify the complexity of data communications and allow non-technical users access to remote network resources. -0- Note to Editors: SBE and the SBE logo are trademarks of SBE, Inc.
