The present invention provides both repertory and abbreviated dialing functions in a telephone dialer that facilitates telephone dialing operation. In particular, by pressing an enablng key the system is enabled for automatic dialing operation to dial a desired telephone number upon selection of a single repertory key or, for example, two keys from the key pad, which establishes coded information that effects automatic dialing operation of the desired telephone number. According to a preferred embodiment of the invention electrical circuitry for the telephone dialer is controlled by a microprocessor, or the like, which includes a central processor unit (CPU). On-hook dialing, telephone and/or speaker muting during dialing and unmuting while waiting for access to a line, security of stored telephone information and dialer use, and adaptability of the dialer to different telephone equipment having different dialing pulse formats may be included in the telephone dialer.
A microprocessor based automatic dialing system for telephone equipment, comprising first memory means for storing information at plural addressable locations representing plural respective telephone numbers, a central processor unit, second memory means for storing program control information for controlling said central processor unit to read out selected information from said first memory means, said central processor unit including command output means for periodically producing command signals commanding the input of information to said central processor unit, and decoding means coupled to said command output means for producing a dialing pulse in response to signals over said command output means.
An automatic dialing system for telephone equipment, comprising a central processor unit, first memory means for storing program control information to control operation of said central processor unit, second memory means for storing information at plural addressable locations representing plural respective telephone numbers, including a distinctly addressable last number dialed location, output means for producing telephone dialing information to effect dialing of a telephone, input means for selecting a telephone number to be so dialed, said central processor unit and first memory means being cooperative in response to said input means to write the information representing the selected telephone number from the addressed location in said second memory means to said last number dialed location and to control said output means only in response to information stored in and delivered from said last number dialed location.
A dialing system for telephone equipment, comprising repertory dialing means for one button dialing of such telephone equipment when the system is enabled, selectively actuatable abbreviated dialing means for generating coded information to effect dialing of such telephone equipment when the system is enabled, said abbreviated dialing means including key pad means for generating such coded information and for manually dialing a telephone number, selectively operable function generating means for distinguishing whether information generated by said key pad means represents coded information to effect abbreviated dialing or manual dialing information, whereby said key pad means may be used for both abbreviated dialing and manual dialing and said repertory dialing means may be used for one button dialing, first memory means for storing information at plural addressable locations representing plural respective telephone numbers, a central processor unit, second memory means for storing program control information for controlling said central processor unit to read out selected information from said first memory means, said central processor unit including command output means for periodically producing command signals commanding the input of information to said central processor unit, and decoding means coupled to said command output means for producing a dialing pulse in response to signals over said command output means.
A dialing system for telephone equipment, comprising repertory dialing means for one button dialing of such telephone equipment when the system is enabled, selectively actuatable abbreviated dialing means for generating coded information to effect dialing of such telephone equipment when the system is enabled, said abbreviated dialing means including key pad means for generating such coded information and for manually dialing a telephone number, selectively operable function generating means for distinguishing whether information generated by said key pad means represents coded information to effect abbreviated dialing or manual dialing information, whereby said key pad means may be used for both abbreviated dialing and manual dialing and said repertory dialing means may be used for one button dialing, a central processor unit, first memory means for storing program control information to control operation of said central processor unit, second memory means for storing information at plural addressable locations representing plural respective telephone numbers, including a distinctly addressable last number dialed location, output means for producing telephone dialing information to effect dialing of a telephone, input means for selecting a telephone number to be so dialed, and wherein said central processing unit and first memory means are cooperative in response to said input means to write the information representing the selected telephone number from the addressed location in said second memory means to said last number dialed location and to control said output means only in response to information stored in and delivered from said last number dialed location.
A dialing system for telephone equipment, comprising repertory dialing means for one button dialing of such telephone equipment when the system is enabled, selectively actuatable abbreviated dialing means for generating coded information to effect dialing of such telephone equipment when the system is enabled, said abbreviated dialing means including key pad means for generating such coded information and for manually dialing a telephone number, and selectively operable function generating means for distinguishing whether information generated by said key pad means represents coded information to effect abbreviated dialing or manual dialing information, whereby said key pad means may be used for both abbreviated dialing and manual dialing and said repertory dialing means may be used for one button dialing, and index means for storing information concerning the telephone numbers stored in the system, a housing for the system, and connecting means for removably connecting said index means to said housing thereby facilitating selective connection and removal of said index means to the dialing system housing.
