A network management system for a multi-layer network having multiple architectural or technological domains includes an inter-domain configuration manager arranged between a set of one or more network service management applications and a set of network element domain managers, each of the domain managers being associated with a particular domain of the multi-layer network. The configuration manager implements network service design and provisioning functions across the domains of the network in conjunction with stored connectivity information characterizing the multi-layer network. The network management system further includes an inter-domain fault manager and an inter-domain capacity manager, which provide respective fault management and transport capacity management functions across the domains of the multi-layer network. The inter-domain configuration manager, inter-domain fault manager and inter-domain capacity manager may be interfaced to the set of network service management applications and the set of network element domain managers through corresponding published Common Object Request Broker Architecture (CORBA) Application Programming Interfaces (APIs).

Inter-domain network management system for multi-layer networks

The present invention relates to a technique for interfacing a plurality of remote terminals, as, for example, Craft Access Terminals (CATs), directly to a central database in a system, such as, for example, a Craft Access System, without interfacing with an intermediate center such as, for example, a centralized Repair Service Bureau and its personnel. An Applications Processor Microcomputer (APM) module includes a General Data Transport (GDT) to provide a powerful microprocessing environment and multiple data communication interfaces, and an Applications Interface Module (AIM) to provide the appropriate signal interface with the database system, the GDT, and the remote terminals. The APM is arranged for connection on one side to both (1) the database system via a trunk; and (2) one or more remote terminals via separate lines to process their calls and permit direct interaction with the database system; and on a second side a via the GDT to a standard IEEE 488 General Purpose Interface Bus (GPIB) for permitting high-speed communication between a plurality K of such APMs. The APM module is designed to provide both high-speed data and control message transmissions over the GPIB between itself and other corresponding APM modules forming part of a network, which other APMs may not be directly connected to a trunk to the central database system. Additionally, the APM module can have the ability to, (1) determine when a high-speed data or control message has been sent over the GPIB to an APM which is not available; (2) restore a disconnected call; and (3) provide appropriate maintenance and other messages to the various network components during the progress of a call.

Compactness and substantially optimum electrical performance are realized in a microwave filter incorporating a housing (21, 22) including an interior surface that forms an enclosed cavity having planar cross sections substantially elliptical in shape (FIG. 3). At least one axis of each ellipse monotonically increases in length with perpendicular distance from a first surface (23) toward a second surface (24). A dielectric resonator (11) is positioned in a predetermined relationship within the cavity and at least two terminal members (30,35) extend from outside the housing (21,22) into the cavity. Electromagnetic coupling between the housing (21,22) and the dielectric resonator (11) is minimized to afford substantially optimum electrical performance of the microwave filter.
