DL TC73
Integrated Service Digital Network (ISDN)
The system analyses the architecture and the operation of the ISDN digital network.
Objectives:
Training of an installation and maintenance technician for ISDN networks,
able to:
- know the operating principles of the
ISDN network
- install complete ISDN systems (telephone exchange, telephones, TA, …)
for audio, video and data transmission
- maintain, troubleshoot and perform
tests and typical operating measurements on the above systems
