Traditionally telemetering systems are based on telephone and similar voice-grade channels. Today new channels such as radio or distribution line carrier (DLC) open new possibilities. The most discussed telecommunication channel is the data highway. It is formed by the combination of cable and of optical fibre networks. In many countries the utilities themselves are involved in the development ...

In large telecommunication networks, alarms are usually useful for identifying faults and, therefore solving them. However, for large systems the number of alarms produced is so large that the current management systems are overloaded. One way of overcoming this problem is to analyse and interpret these alarms before faults can be located. Two different techniques were developed and setup to re...

Software management in existing telecommunication networks is used for: • Software upgrade: new or modified functionality are added to the Network Element (NE) by installing new software releases • Software correction: the basic functionality is not changed. It is usually by means of patching or by limited substitution or addition of software modules . In this paper the term “upgrade” refers, u...

In the past, telecommunication technologies did not present any particular problem for persons with visual disabilities. The telephones themselves were auditory in nature and could be operated by touch. As telecommunication begins to incorporate video and as telecommunication devices become more complex (including the incorporation of visual displays), new barriers are appearing. Fortunately, a...

To increase productivity and product quality in software development, companies invest in qualification of their engineers, improvement of their development processes and many other approaches. We believe that in addition a much more powerful way to go in the above direction is to try new complementary organizational forms of how people work together. Specifically the network form seems to fit ...

Up to now, a lot of efforts have been made for the management of telecommunication networks and equipment, but less effort has been made for the realization of higher-layer service and business management. Common Object Request Broker Architecture (CORBA) provides the infrastructure for interoperability of various object-oriented management applications in a distributed environment, and being w...

This contribution describes a framework with organizational and operating concepts for the management, i.e. supervision and control of complex dynamic systems (processes), like networks, factories, power plants or transport systems. This kind of system operation has also been called supervisory control [10], [15]. These applications are characterized by a complex allocation of tasks between sev...
