For reliable communications to take place on a network, things like the physical method of signaling and the meaning of each signal or series of signals must be defined ahead of time. Create a simple physical network and agree on some basic rules for communication in order to send and receive data. This will be a digital network based on the American Standard Code for Information Interchange (ASCII). It will be similar to the old telegraph Morse code-based systems. In these older systems the only means of communicating over long distances was by sending a series of dots and dashes. | Cisco Svstems I Lab Communications Circuits Objective Design a simple communication system that is fast and reliable. Build the system using common materials. Test the system. Background Preparation For reliable communications to take place on a network things like the physical method of signaling and the meaning of each signal or series of signals must be defined ahead of time. Create a simple physical network and agree on some basic rules for communication in order to send and receive data. This will be a digital network based on the American Standard Code for Information Interchange ASCII . It will be similar to the old telegraph Morse code-based systems. In these older systems the only means of communicating over long distances was by sending a series of dots and dashes as electrical signals over wires between locations. Although the technology used will be more simple than real systems many of the key concepts of data communications between computers will arise. This lab will also help to clarify the functions of the layers of the OSI model. Each team must design build and test a communications circuit with another team. The goals are to communicate as much data as quickly and with as few errors as possible During this communication spoken written or nonverbal communication of any kind is not allowed. The only communication allowed is over the wire. The teams must agree on the physical connections and on the coding to use. One team will send a message to the other team. The other team must interpret the intended message without knowing ahead of time what the message was. Keep the OSI model in mind as the system is designed. Prior to starting the lab the teacher or lab assistant should have one multimeter available for each team of students and various items for construction of a simple communication network. Work in teams of two to four. The following resources will be required. Review the purpose of each of the following required items because it will
