REPERTORY DIALER TELEPHONE SET WITH REGISTER STORAGE OF THE DIGITS |
摘要 |
In an electronic type repertory dialer telephone set, direct station selection for recording or automatically dialing out is provided by a name button switch array, each button accessing an associated shift register memory. A clock pulser and counter circuit initiates an automatic call sequence in response to the electronic detection of dial tone after a particular memory has been designated.
