The ComBAT (Common Broadband Applications Testbed) project aims to show how multi-media services can be offered to customers in the same accessible way that supermarkets provide conventional products. ComBAT provides an architecture for integrating the control and management of services and users. This is based on the concept of access agents, 'semi-intelligent' agents which interact with users. ComBAT builds on the work of the TINA Consortium (TINA-C), refining this work through the use of an enterprise model, which provides a commercial context for applying advanced management concepts from TINA-C in ComBAT.< >

The broadband integrated services digital network (BISDN) will become the ubiquitous network of the future, which will be required to support a wide range and complex set of services to the end user. In order for a network operator to provide a full service network to all its customers it will be necessary to provide the full range of broadband ISDN services to end users connected to the broadband local exchange (BLE) via a broadband access network (BAN) which will replace part or the whole of the local line distribution network. To ensure that the full range of services can be delivered by the BAN to the end users in a consistent and correct manner, the Council of the European Commission (CEC) have given the European Telecommunications Standards Institute (ETSI) a mandate to define an ATM (i.e. cell) based interface between the BAN and BLE which will be called V/sub b5/. The ETSI have produced a technical requirement which will form the framework for the detailed specification of V/sub b5/. V/sub b5/ shall be capable of supporting narrowband services, symmetrical and asymmetric broadband services and broadcast services. The paper describes the major capabilities and features of the V/sub b5/ interface by focusing on the general architecture, service architecture, protocol stack and BAN/BLE configurations. The paper recommends that the narrowband stepping stones of V5.1 and V5.2 are progressively rolled out into the network to lay the foundations for the support of V/sub b5/ and to build operational experience in the support of V5 interfaces.

This paper addresses the direction that signalling may take in the future. It is not meant to be a definitive document on the exact requirements that a network must support to accommodate applications. The term signalling is used to mean call control, or a set of application or some other monolithic piece of software. To date except for the BISUP specification, all of the signalling systems (i.e. CCITT No.7) are classified as monolithic. This term is used to indicate that the call control application and the signalling protocol are specified in one place.

This paper presents a vision of an architecture for the next generation public telecommunications network. It considers the core network and the variety of access mechanisms. It identifies ATM (asynchronous transfer mode), SDH (synchronous digital hierarchy) and ODP (open distributed processing) as a key enablers to meet the vision. Having given an insight into the vision of the network, it suggests the possible positioning of distributed computing technologies such as CORBA (Common Object Request Broker Architecture).< >

This paper looks at current directions of intelligent network (IN) implementations and possible changes resulting from the latest concepts of information networks. By way of introduction, the paper reviews the historic introduction of intelligence in telephone networks which has led towards the emergence of 'classical' IN principles. It then looks briefly at expectations for future evolution of public network intelligence. Classical IN principles have typically set the scene for network operators' IN implementation strategies, increasingly using the ITU CS1 as an initial requirement template. However, whilst there is general agreement that CS1 provides a working framework for the short-term, the contents of future ITU Capability Sets are less clear in definition. Meanwhile, operators are finding that the complexity of existing transport networks is increasing because of new embedded service solutions introduced to meet short-term service needs. There is a growing awareness, in the face of expected future service demands, that the traditional IN approach has limitations. Consequently, some operators are seeking to readjust and clarify their targets for their evolutionary strategies. There is a growing expectation that the work being done in the TINA Consortium is rapidly laying out the basis for the future telecommunications architecture principles.< >

IN (intelligent networks) and TINA (Telecommunication Information Networking Architectures) are emerging technologies that try to address some of the critical problems in today's fast-evolving telecom networks, by adopting architectural principles. IN is more related to physical architectures, TINA to SW architectures. This paper presents a service scenario with video conferencing and joint document editing, where IN and TINA principles co-exist. Based on the analysis of such a scenario, advantages and disadvantages of the two architectures are presented, as well as compatibility issues. The main conclusions are that there is no major incompatibility and that several advantages can be gained by combining IN with its "newer relative" TINA. The aim of presenting the analysis and the conclusions in relation to a concrete example scenario is that of reducing the level of abstraction and increasing the level of comprehension of all the concepts presented.< >

Today's intelligent networks (INs) could be described as "closed". That is, IN services are provided by the same organisations that operate the network infrastructure used to provide those services. (i.e. the service control points (SCPs) and service switching points (SSPs)). Management of these INs is also provided by the network operators, although some major customers are allowed to manage certain aspects of their services. (e.g. the changing of certain amounts of data). "Management" for the purposes of this paper is used to describe all actions necessary to create, deploy and maintain an IN service in a given network. This covers both "service management" and "network management". "Service management" is concerned with such things as registering new customers, deploying new versions of services and ensuring that data is correct. "Network management" is concerned with the management of the physical resources of the IN such as the SCPs, SSPs and their associated signalling entities.< >

The authors argue that the arrival of broadband technology, coupled with deregulation in the marketplace, will lead to a revolution in the way telecoms services are delivered to customers. They introduce the TINA Consortium project, which aims to define a next generation Telecommunications and Information Networking Architecture (TINA). The authors believe that TINA-C's opportunity is to become the architecture for the delivery of broadband services. They show how a next generation approach such as TINA can integrate the telecomms and Internet approaches. Conclusions for the TINA-C architecture and its adoption in the market are discussed.< >
