Signalling in Telecommunicatnions Networks
This course concerns the structure and principles of operation of signalling systems SS7 and DSS1. Protocol stuck and frame structures used in these signalling systems are described. The course is divided into two parts. In the first part, Lessons 1 to 6, the basic knowledge about signalling in ISDN network is given. Description of signalling messages which are used in the second part of the course is also given. The second part contains a set of exercises for students. In each exercise examples of call set-up procedures for basic calls and supplementary services are given. Students have to configure an ISDN access (if applicable), assign numbers to terminals, set-up a connection and observe signalling messages during the call set-up procedure. During the demonstration detailed structures of signalling messages exchanged between the user and the network and between network nodes can be viewed, depending on considered service and configuration chosen.
Under-graduate and graduate level students of communications engineering, computer science, and electrical engineering. Exercises may be also useful to communications engineers and network management stuff of telecom operators.
The aim of the course is to give students and participants the basic knowledge about signalling in ISDN networks and enable students to get familiar with structures of signalling messages, and operation of call control procedures of basic call control and supplementary services control.
Basic knowledge on telecommunication networks, integrated services digital networks, user-network interfaces in ISDN, reference configuration for subscriber installation, basic functions of signalling in telecommunication networks
The whole course material is accessible through the Internet, and is designed to be viewed and browsed using IE 5.0 (or higher) with Java Script and Macromedia Flash 5 (or higher) plugins.
