TTMER38: Exercises on the telecommunication test network

Introduction:

During measurement students can study private telecommunication networks, their signaling and services.

We will execute the laboratory exercise on the PSTN/ISDN subnetwork of the test network. We will retrieve information from the database of the BCM 50 VoIP exchange and Definity exchanges. It provides a possibility to show, that although handling surfaces of the two exchanges are different, the databases store actually similar information. During the exercise we will use EQS133 (this is in Hungarian) protocol analyzer to study the call signaling of the different exchanges and oscilloscope to examine the signal shapes on the line interfaces of different telephones.
