    A virtual path (VP) based asynchronous transfer mode (ATM) network architecture that supports leased-line services is described. ATM multimedia leased-line services, including user access to VPs, tailored VP capacity, guaranteed quality of service, and reduced transmission cost, are discussed. It is argued that some issues remain to be resolved before fully realizing the services. The issues inclu... View full abstract»

    A photonic asynchronous transfer mode (ATM) switch architecture for ATM operation at throughputs greater than 1 Tbit/s is proposed. The switch uses vertical-to-surface transmission electrophotonic devices (VSTEPs) for the optical buffer memory, and an optical-header-driven self-routing circuit in contrast with conventional photonic ATM switches using electrically controlled optical matrix switches...

    The trial implementation of Bellcore's advanced call management services (ACMSs) is reviewed. The ACMS used an experimental screen-based telephone with a context-sensitive visual display and context-sensitive soft keys. ACMS was based on a Bellcore research prototype, the customer premises equipment (CPE) network integrator (CNI), which consists of inband signal (tone) detection circuitry, softwar...

    The impact of telecommunication management network (TMN) concepts when applied to the management of newly emerging network architectures is illustrated using the example of intelligent networks (INs). An in-depth comparison of TMN and IN architectural aspects leads to a number of conclusions showing a significant degree of commonality between the two networks. The IN is analyzed as a telecommunica... View full abstract»
