Abstract
1,238,258. Repertory diallers; keysenders. TELEPHONE MFG. CO. Ltd. 2 Feb., 1970 [25 Feb., 1969], No. 9966/69. Heading H4K. A repertory dialler comprises a push button telephone instrument provided with Store and Send buttons in addition to the digit buttons. The instrument is also provided with a call switch which performs the function of the cradle switch and allows a call to be initiated and the line to be monitored by a loud-speaker without removing the handset. The instrument can be used in the normal manner and the number "dialled" on the digit buttons. If the Send button is depressed each digit button controls the transmission of a complete telephone number. Ten complete numbers are stored in a non- destructive store and each register is accessed by a digit button. To record a number the store button is operated followed by the relevant digit button and then the number is "dialled" into the register erasing any existing number. Simultaneous transmission and recording is obtained by operating the call or cradle switch in addition to the store button. The number is stored in binary form and can be transmitted either as loop disconnect impulses or tones by a code generator which includes a timing pulse generator. The switch buttons are of the pushpush type and include signal lights and can be reset automatically when the handset is replaced.
