Abstract
A communication apparatus comprises a communicating circuit, a connecting unit for connecting a telephone or the communicating circuit to a line, a disconnecting unit for disconnecting the telephone from the line, a call reception detection circuit, a detection circuit for detecting a hook state of the telephone, an output unit for outputting a signal indicating that the call generation limitation mode has been set, a display for displaying that the apparatus is in the call generation limitation mode, and a dial signal transmission unit. A call generation of an attached telephone can be limited with a simple construction and a call generation limiting function of the data communication apparatus can be certainly realized.
