TTMER2: Call Paths Testing - "In-circuit" measurements on ISDN and VOIP network elements
Introduction
During this laboratory exercise students will learn about characteristic parameters of the
Call Paths and Call Path Circuits (or ISDN B-channels) of the telecommunication networks.
Main characteristics of the tested call paths:
Students will make tests in the following topics:
- Transmission performance characteristics of call paths according ITU-T G.712 and the analizers for their testing.
- Circuit switched speech transmission on packet switched network. Implementing VoIP trunks.
- A beszédátviteli út egyes áramköreinek (szürő, A/D átalakító, hibrid) in-circuit vizsgálata:
- A berendezések megbontása nélkül,
- a berendezés interfész csatlakozóin keresztül,
- a fenti szabványos eljárásokkal és eszközökkel.
- In-circuit testing of the particular circuits (filter, A/D converter, hybrid) of the call path.
- Without disassembling the equipment
- through its interface connectors
- using standardized procedure and tools.
