Computer communications student design projects

Three undergraduate design projects in the field of computer communications are described: a microprocessor-controlled private branch exchange (PBX); a ring type local area network; and a computer network design software project. These projects are particularly useful for allowing students to integrate course work in communications, microprocessors, and digital logic and software. Readings for each project which are suitable for undergraduate students are also listed. The undertaking of these projects is divided into four phases. Initially, the students perform reading on the technology in question. This is followed by an initial hardware design and/or software design. During the next (construction) phase, the initial plan is usually modified. Finally, experimentation and modifications are carried out with the completed system. Students typically underestimate the time it will take to produce operational hardware and software. Thus, the faculty advisor´s most important task is to see that it is completed in time to allow experimentation
