Source: Alcatel Telecommunications Review n 3rd Quarter 1997. p 200-207 CODEN: ATREFX ISSN: 1267-7167 Publication Year: 1997 Abstract: ALMA Vision is Alcatel’s Integrated Network Management ŽINM. solution. It consists of a set of pre-packaged modules which can be assembled according to each operator’s needs. This approach helps them to deliver cost-effective managed services with customer-defined quality of service levels, to control and reduced network operating costs, to optimize the use of resources and to improve services. Two products are presented, namely: ALMA Expert, a tool for building intelligent network and service management applications; and ALMA Fault Expert, a predefined application dedicated to intelligent fault management. 2 Refs.

Corporate Source: Delft Univ of Technology, Delft, Neth Source: Computer Standards & Interfaces v 18 n 5 Jun 1997. p 431-450 CODEN: CSTIEZ ISSN: 0920-5489 Publication Year: 1997 Abstract: It is now customary to think about standardization in terms of economic and political interests. That analyzing committee processes from a technological vantage point might be fruitful as well, is often neglected or even denied. This article explores the extent to which technological paradigms explain the outcome of committee processes. It is argued that, especially in fields of converging technologies such as telematic services, paradigms explain patterns of interest negotiation in standards development. The argument is substantiated with the findings of case studies on three base Open Systems Interconnection ŽOSI. standards: the transport, session and message handling protocols.

Publication Year: 1997 Abstract: The growth of computer networks, in particular the Internet, led to the creation of methods for libraries that provide services for users. One of these services which can be enhanced and delivered is the access to the library catalogue. The development of standardized communication interfaces to the actual database and search engine, the search and retrieve protocols, made it possible for users with appropriate client software to access any server supporting the standard interface. Two standards are developed for this purpose: the ISO Search and Retrieve ŽSR. and the ANSI Z39.50. The design and implementation of the application gateway allows both ISO-SR and Z39.50 systems to interoperate transparently on transport control protocolrInternet protocol. 36 Refs.

Title: OPEN SYSTEM CONCEPTS FOR MODULAR AVIONICS Author(s): Thedens, John R. Corporate Source: Rockwell, Cedar Rapids, IA, USA Source: IEEE Aerospace and Electronic Systems Magazine v 12 n 10 Oct 1997. p 30-34 CODEN: IESMEA ISSN: 0885-8985 Publication Year: 1997 Abstract: Advanced communications, guidance and navigation systems play key roles in determining superiority of one combat aircraft over another. The use of advanced technology is essential to meeting the mission requirements of present as well as future aircraft. Modular avionics are being used in next generation aircraft, such as the Air Force F-22 fighter and the Army Comanche helicopter, as the means of achieving higher levels of performance, including reduced volume and improved adaptability, maintainability, and expandability. New system acquisitions such as Joint Strike Fighter will attempt to achieve these same performance levels but at dramatically reduced life cycle cost. Retrofit applications will also take on increasing roles in meeting this affordability need as the Department of Defense ŽDoD. struggles to maintain readiness in the face of the shrinking defense budget. The government is encouraging the use of open standards practices as a means of addressing the affordability issue. The Open Systems Joint Task Force ŽOS-JTF., formed in September 1994, is chartered to ‘sponsor and accelerate the adoption of open systems in weapons systems and subsystem electronics to reduce life-cycle costs and facilitate effective weapon system intra- and interoperability.’ The purpose of this paper is to relate the concept of open systems to modular avionics. It discusses the key attributes of an open systems approach and identifies key technologies necessary for its success. ŽAuthor abstract . 7 Refs.
