DELORENZO DL-TC72 Wide Area Network Wan E Internet
Product Information
The TC72 is a Telecommunications and ICT training package designed to provide
engineers with the necessary knowledge andskills for the installation and
maintenance of Digital Telecommunications and Internetworking systems. It
serves as a base training module and prepares engineers for further training
on ISDN networks, Wide Area Networks, and the Internet. The package covers
various communication protocols including HDLC, SDLC, X.25, Frame Relay, and
ATM. It also provides an
introduction to the communication architecture of the OSI model and covers
topics such as the OSI reference model, format of information, and different
levels of the OSI model.
Specific topics covered in the package include
- HDLC/SDLC Protocols: Introduction to HDLC/SDLC protocols, structure of HDLC frames, types of frames, and examples of HDLC sessions.
- Frame Relay Network and Protocol: Introduction to Frame Relay network and protocol, virtual circuits (permanent and switched), congestion control parameters, throughput management parameters, LMI (Local Management Interface), and format of Frame Relay frames.
- X.25 Package Switching Network: Characteristics and operating parameters, format of level 2 frame, format of level 3 package, addressing in the X.25 network.
- ATM (Asynchronous Transfer Mode): Characteristics and operating parameters, format of ATM cell, connections, virtual paths and channels, and the ATM reference model.
Product Usage Instructions
To use the TC72 Telecommunications and ICT training package, follow these steps
- Ensure that all required components are included in the package. These include the TC72-MP module, 2 LCD displays for frame visualization, and simulation boards for different protocols (HDLC, Network X.25, Frame Relay).
- Connect the LCD displays to the TC72-MP module for frame and package visualization.
- Select the desired simulation board based on the protocol you want to simulate (HDLC, Network X.25, or Frame Relay).
- Insert the selected simulation board into the insertion system of the TC72-MP module.
- Power on the TC72-MP module and LCD displays.
- Follow the training materials provided to learn about the communication protocols and their operation.
- Use the LCD displays to visualize the frames and packages exchanged by the communication devices during simulations.
- Experiment with different scenarios and configurations to gain practical experience.
- Refer to the user manual and training materials for troubleshooting and maintenance guidelines.
Note It is important to follow safety precautions andguidelines provided in the user manual while using the TC72 Telecommunications and ICT training package.
