Ž . The ATM Asynchronous Transfer Mode network is regarded as effective for a multimedia telecommunication environment that enables high-speed and broadband communication. This paper reports on the system architecture and Ž . design concept of the FETEX-150 ESP Enhanced Switching Platform which has been designed as an ATM switch in a public broadband network. To track the latest ATM standards a...

Fraud causes substantial losses to telecommunication carriers. Detection systems which automatically detect illegal use of the network can be used to alleviate the problem. Previous approaches worked on features derived from the call patterns of individual users. In this paper we present a call-based detection system based on a hierarchical regime-switching model. The detection problem is formu...

As of late there has been an immense increase of data within modern society. This is evident within the field of telecommunications. The amount of mobile data is growing fast. For a telecommunication operator, this provides means of getting more information of specific subscribers. The applications of this are many, such as segmentation for marketing purposes or detection of churners, people ab...

Multiprotocol Label Switching (MPLS) is a revolutionary packet forwarding WAN technology that operates between Layer 2 and Layer 3 of the OSI model, which has been classified as Layer 2.5. It is placed between the two layers because it integrates the fast paced switching, that takes place in the data link layer ,with IP routing, that takes place in the network layer, to do what is called label ...

Kurzfassung: Reverse and reengineering of large and complex software systems is a difficult task. As a result, many methods and tools for reverse and reengineering have been developed so far. However, the work in this field has concentrated on sequential, and untimed systems, mainly for business applications. The majority of the approaches deals with decomposing monolithic systems, decoupling u...

This paper investigates the role of pitch accent information in spoken-word recognition in listeners in Fukushima, Japan, whose dialect is accentless. Previous research revealed that accentless listeners were less sensitive to pitch accent than Tokyo Japanese listeners. The present study asked whether middle-aged listeners’ use of accent information would differ from that of young listeners. 40...
