Abstract
A telephone apparatus having the standard ten digit keys and two special keys, and in the handset the conventional switchhook. By manual operation of the two special keys and the switchhook the apparatus can be operated in any one of a plurality of modes, at least some causing transmission of stored sequences of digits in response to entry of an abbreviated address or in causing redialing. In one mode data signals are produced and transmitted in response to not only the digit keys but also the special keys as well. A controller operates the apparatus and is connected to a dial sender which converts the data signals into a multi-frequency signal which is transmitted by a telephone network to a repeater station.
