A network of over eighty UNIXcomputer systems has been established using the telephone system as its primary communication medium. The network was designed to meet the growing demands for software distribution and exchange. Some advantages of our design are:

The startup cost is low. A system needs only a dial-up port, but systems with automatic calling units have much more flexibility.
No operating system changes are required to install or use the system.
The communication is basically over dial-up lines, however, hardwired communication lines can be used to increase speed.
The command for sending/receiving files is simple to use.
