Telephone calling card dialer
First Claim
1. A dedicated telephone dialer comprising:
- a. a case having an interior cavity and a grille;
b. generating means, contained in said cavity, for generating DTMF tones corresponding to a specific abbreviated telephone number at a first speed, waiting for a short period, and then generating DTMF tones corresponding to a specific access number at a second speed;
said second speed being slower than said first speed;
a telephone number having eleven digits starting with a "1" and a toll free area code;
an abbreviated telephone number having ten digits and being equal to said telephone number minus the initial "1"; and
c. initiating means, mounted on said case and electrically connected to said generating means, for initiating said generating means;
whereby authorized connection to a calling card system is made by removing a receiver from a telephone, dialing said inital "1" on said telephone, placing the grille of said dedicated telephone dialer adjacent to the transmitter of said receiver and initiating said dedicated telephone dialer by said initiating means.

Abstract
A dedicated telephone dialer capable, in one embodiment, of automatically dialing a preprogrammed calling card abbreviated telephone number at one speed, waiting for a short period and then dialing a preprogrammed access number and, optionally, a preprogrammed personal identification number (PIN) at a slower speed. In second and third embodiments the dedicated telephone dialer is capable of automatically dialing a preprogrammed calling card abbreviated telephone number at one speed upon first activation and, dialing a preprogrammed access number and, optionally, a preprogrammed PIN at a slower speed, upon second activation. This invention comprises electrical circuitry for generating DTMF tones, logic for dialing the requisite numbers, and a switch, or switches in the case of the third embodiment, for initiating the dialing sequence or sequences. The electrical circuitry includes a replaceable power source, a number generating device, and a tone generating device. The dialing logic is contained in a microprocessor. The circuitry and logic device are all contained within a case which includes a grille to allow penetration of the DTMF tones. The switch is mounted on the exterior of the case. To use this invention it is held up to the transmitter of an off-hook telephone handset, the first digit of the access number is dialed from the telephone keypad then the switch or switches on this invention are activated.
