Abstract
A control system has two switches for connecting a telephone device and a data device to a common telephone line. Separate circuits are provided to sense the current flowing between the telephone line and each of the devices. The circuits are coupled to the switches so that when the sensed current for one of the devices exceeds a given level, the switch for the other device is activated to disconnect the other device from the telephone line.
