Abstract
Abstract A communication terminal adaptor, or an automatic dialer, for connecting a communication terminal such as a facsimile apparatus and a telephone line network, is capable of handling both the push button signal and the dial pulse signal in mixed manner, and transmitting the identification information of the communication terminal, stored in advance in the adaptor, upon receiving the tone prompt signal from the destination station without referring to the communication terminal. Thus the telephone connection can be made in simpler and more prompt manner.
