Abstract
PURPOSE:To attain memory dialing by a standard 2-wire telephone set by providing a means detecting a special number, and a means reading the data corresponding to its specific number from the memory and turning on/off the external line/internal line switching relay. CONSTITUTION:A detection means 14 detecting a dial pulse sent to a talking line based on the dialing of standard telephone sets 51-5n, a memory storing the dial number based on the detection output of the means 14, and a control means 17 switching on/off the external/internal line switching relay based on the dial number read from the memory by the control dial from the standard telephone sets 51-5n are provided. Contacts l1<1>, l1<2>-ln<1>, ln<2> of the external/ internal line switching relay are used to send the dial pulse based on the memory. Thus, the memory dial by dial pulse is applied, then the memory dial is applied by the standard 2-wire telephone set without adding any special dialing means.
