The Alcatel multiservice private network architecture enables a company to obtain the unrestricted benefit of all services offered by an in-house ISDN, irrespective of its geographical structure. Based on a particulary rich signalling protocol, de- signed in the ISDN context, this architecture provides a set of technical solutions which guarantee the evolutivity of the network, while optimizing the links established between the different nodes, and maintaining the homogeneity of the features available to the user. Implemented over a ten year period of time, Alcatel's program has evolved from a homogeneous solution allowing inter- connection of PBXs from the OPUS4000 product line, to an open, ISDN solution, allowing heterogeneous ISPBX networking using the Alcatel Business Communications (ABC) protocol.

This paper describes Bell Atlantic's implementation of UItra-Forward, a network service platform that interacts with customers and switching systems, allowing users tochange their telephone 'call forwarding' service from any tone dialing tek phone. A single service node - the Ultra *Forward Platform - can control all of the switching systems in a large service area, allowing the telephone company to implement and change new services quickly and economically.

M2000, the word's largest private telecommunications network is a state-of-the-art integrated digital voice-data-image network with service having begun in October 1989. M2000 includes switched voice service (including voice and voiceband data), switched data service (circuit switched capability includ ing 56 Kbps and 64 Kbps clear), packet switched service (X. 25 data service including packet and electronic mail), video trans mission service (teleconference and teleseminar at full motion and nearfull motion), dedicated transmission service, and ISDN (including RRI and PRI). The M2000 network presents a unique challenge to the network planner: the creation of a network with the size and geographic distribution normally associated with public net works and the user sophistication, diversityand special needs normally associated withprivate networks. This paper highlights the services requested by the GSA and the architecture being implemented by AT&T, including network elements feature capabilities, operations architecture, routing scheme, ISDN pIans and evolution. Special arrangements for private switched network operations and adminstration are detailed as well. This paper is of interest to both providers and users of large private voice/data/image networks to understand trends in network and operations technology.

There is a great and increasing need to understand past development software quality from the customerperspective. By integrating measurement concepts from the service-quality field into this understanding we can arrive at a new measurement perspective, 'software service quality". Attention is given to software service quality measurement in the telecommunications switching environment. Environment dynamics and the composition of customer satisfaction are explained. Measurements are made at gaps in the software service-delivery process, and management is responsible for the success of the measurement process. Software-service quality measurement is a strategic tool that can help increase a supplier's competitiveness.

The second generation system for digital mobile-radio telecommunications in Europe specified by GSM is comprised ofthe mobile-radio subsystem and the network subsystem. This clear cut partitioning of network functions is well suited to the Intelligent Network approach where in-service digital switches are used to interconnect fixed land networks to mobile networks and where specific mobile functions can be embedded in dedicated mobile network equipment Total separation between mobile and fixed telecommunication resources also has advantages regarding network evolution, since new network components can be tested individually before final integration with minimum effect on installed equipment. Mobile station roaming generates large amounts of signalling traffic without significant impact on switching. The Intelligent Network approach isolates such signalling from the normal telephone signalling traffic to process it separately. Moreover, the Intelligent Network ensures access not only to expanding public network services but also to oncoming ISDN data services up to 9.6 KW.

Thispaper evaluates the performance of an exchange from the traffic and dependability point of view with regard to the CMT performance objectives[1], [8]. A methodology is defined on the basis of three steps: characterization of the environment, characterization of the resources, Performance evaluation CCFIT parameters This method may constitute a guideline for manufacturers and users, when investigating the performance of an exchange. As an example the method is applied to the Alcatel E10 OCB283 system for the evaluation of two CCITT performance parameters.

The introduction of Common Channel Signalling, CCS, and Telecommunications Management Network [1], TMN, creates a new security situation in the public telecommunication area Earlier, public exchanges were managed individually, and to some extent manual intervention locally at the switch was the only way to intervene with the switch's operation. CCS and TMN create new and powerful possibilities for network management, because they enable large portions of the network to be diagnosed, reconfigured or simply put out of operation by simple commands issued at computer terminals in the management network.

With the introduction of the Integrated Services Digital Net work (ISDN), Signalling System No. 7 and service-independent Intelligent Network (IN) capabilities in switches and other network entities, such as databases, many opportunities have emerged for PIT Administrations to promote new telecommunications services. This paper addresses how PYT Administrations' existing public switched telephone networks can be evolved to create opportunities for Intelligent Networks and their services. Key challenges relating to deployment, architecture, and customer support of Intelligent Networks and their services will be covered.
