Abstract

The automatic storage and dialling device has a pushbutton keyboard for entering telephone numbers and for controlling the various read and programming operations for the store. The contents of the store can be verified. A decoder decodes signals transmitted along the telephone line and signals the absence of a subscriber set called. The device can be disconnected automatically from the telephone line and the store may be cleared. The telephone numbers may be retained temporarily or permanently. The telephone line may be switched to either of two modems.
