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
sm, Interface S: access control to channel "D", Interface S: passive bus (bus-S), The physical level of the primary access
Educational Path: The educational path of this Training Package covers the following subjects:
ISDN and OSI Model - The Network Level Structure of the message, The information elements of the message: Protocol discriminator, Call Reference, Message Type and others, Example of base call
General concepts on ISDN Generalities on the ISDN network, Structure of the ISDN network Basic structure of the ISDN network Topography of an ISDN network, Reference points - Interfaces "U","T","S","R", Special interfaces, The OSI Model How to connect to the ISDN network Connection through Base Access, Pointto-multipoint and point-to-point configurations, Configuration of the telephone numbers, Connection through Primary Access ISDN and OSI Model: The Physical Level Interface U, Interface S: line code, Interface S: frames, clock and synchroni-

ISDN and OSI Model - The Link Level The structure of the frame HDLCLAPD, The structure of the frame LAPD: the fields FLAGS and ADDRESS, Control, Information, FCS, The frames LAPD, Activation/deactivation of level 2 and management of the TEI, Example of a session at level 2
The components of an ISDN network The ISDN exchange, The ISDN telephone, The Terminal Adapter, Devices for Video Communications, Protocol Analyser ISDN telephone communication The ISDN exchange, ISDN single-number and multi-number telephone network
List of modules: TC73-MS: ISDN network This module shows the block diagram of the ISDN network, with reference to the S bus. The connections of the digital ISDN (PABX) exchange to the terminals are performed through this module. Furthermore, it includes the following diagrams: Connector RJ45. Point-point connections. Point-multipoint connections. S bus TC73-DP: ISDN Digital PABX 2 ISDN So (Base Access) interfaces. Standard Euro-ISDN. Programmable services. TC73-DA: ISDN Terminal Adapter (Quantity two) ISDN So interface. V24/RS232 serial interface. Speed 115 kbps. Programmable through AT controls.
ISDN protocol analysis Use of the ISDN tester, Protocol analysis with tester and PC
TC73-DT: ISDN Telephone (Quantity two) Keyboard and display. Multi-number. Programmable.
ISDN data communication The Terminal Adapter, Programming the Terminal Adapter, Connection between single-number TAs and connection between multi-number TAs, Connection of multiple devices on the S bus.
TC73-DN: Protocol analyser Level 2 and level 3 ISDN analyses. ISDN So (Base Access) interface. Simulation of protocols. Possibility of analysis through external PC. Rechargeable batteries power supply.
