A versatile, low cost system for implementing CATV auxiliary services is presented which focuses upon a basic unit operating over two-way coaxial networks. A wide variety of services can be implemented with the basic hardware. In addition, this unit can be extended to implement more complex functions in a modular manner requiring the cost increase only at the specific locations where the more complicated task is undertaken. This type of system lends itself to many areas such as security, energy management, traffic control, industrial data gathering and process control, CATV system status monitoring and spectrum analysis, hotel security and room services, low and medium speed data communications, addressable taps, premium CATV control, remote switching of all kinds and a host of others.
