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.

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.
