Abstract

A combined telephone AED simply integrates the function of a telephone and an alphanumeric entry device required for alphanumeric paging into a single unit by making use of the handset cradle switch to reset the unit from page mode to telephone mode whenever the handset is lifted. Paging operation is simplified through pre-stored entries in a directory giving both voice and paging numbers with the appropriate number being identified by the previously selected mode of the operation of the unit. Special purpose paging and speed dial buttons serve the combined function of identifying a mode of operation and initiating a search of the directory to reduce the number of keystrokes required of a user during typical operation.

Claims

1. A combination telephone and alphanumeric entry device unit, the combination unit comprising:

a keyboard having keys generating key signals when activated by a user, the keys including a page mode key and a speed dial mode key;

a modulator for transmitting telephone signals and paging signals on a phone line;

an electronic memory holding names linked to at least one of a voice telephone number and a page telephone number;

a microprocessor communicating with the keyboard, the electronic memory and modulator, and operating according to a stored program to;

(i) receive key signals identifying a name;

(ii) search the electronic memory to identify at least one of a voice telephone number and a page telephone number linked to the name;

(iii) if the page mode key is pressed and a page telephone number has been obtained in step (ii) returning to the user the page telephone number;

(iv) if the speed dial mode key is pressed and a voice telephone number has been obtained in step (ii) returning to the user the voice telephone number.

2. The combination telephone and alphanumeric entry device unit recited in claim 1 wherein the microprocessor returns the telephone number of steps (iii) and (iv) to the user by activating the modulator to output phone signals to dial the telephone number.

3. The combination telephone and alphanumeric entry device unit recited in claim 1 wherein electronic memory also links the name to a pager type and a pager identification number and wherein if the pager type is an alphanumeric type the microprocessor returns the telephone number of steps (iii) and (iv) to the user by activating the modulator to output phone signals to dial the telephone number and to output pager signals to transmit the pager identification number.

4. The combination telephone and alphanumeric entry device unit recited in claim 1 including a telephone handset fitting within a cradle when not in use, and a handset switch providing a handset up signal indicating the handset has been removed from the cradle wherein electronic memory also links the name to a pager type and a pager identification number and wherein if the pager type is a numeric type the microprocessor returns the telephone number of steps (iii) and (iv) to the user by activating the modulator to output phone signals to dial the telephone number when the handset up signal is received.

6. The combination telephone and alphanumeric entry device unit recited in claim 1 wherein the microprocessor returns the telephone number of steps (iii) and (iv) to the user by activating the modulator to output phone signals to dial the telephone number.

7. The combination telephone and alphanumeric entry device unit recited in claim 1 wherein electronic memory also links the name to a pager type and a pager identification number and wherein if the pager type is an alphanumeric type the microprocessor returns the telephone number of steps (iii) and (iv) to the user by activating the modulator to output phone signals to dial the telephone number and to output pager signals to transmit the pager identification number.

8. The combination telephone and alphanumeric entry device unit recited in claim 1 including a telephone handset fitting within a cradle when not in use, and a handset switch providing a handset up signal indicating the handset has been removed from the cradle wherein electronic memory also links the name to a pager type and a pager identification number and wherein if the pager type is a numeric type, the microprocessor returns the telephone number of steps (iii) and (iv) to the user by activating the modulator to output phone Signals to dial the telephone number when the handset up signal is received.

5. A combination telephone and alphanumeric entry device unit, the combination unit comprising:

a keyboard having keys generating key signals when activated by a user, the keys including a page mode key and a speed dial mode key;

an alphanumeric display;

a modulator for transmitting telephone signals and paging signals on a phone line;

an electronic memory holding names linked to at least one of a voice telephone number and a page telephone number;

a microprocessor communicating with the keyboard, the electronic memory, and the modulator, and operating according to a stored program to;

(i) display a prompt on the display requesting a name upon the activation of one of the page mode key and the speed dial mode key of the keyboard;

(ii) receive key signals identifying a name;

(iii) search the electronic memory to identify at least one of a voice telephone number and a page telephone number linked to the name;

(iv) if the page mode key was pressed, returning to the user the page telephone number linked to the name in the memory;

(v) if the speed dial mode key was pressed, returning to the user the voice telephone number linked to the name in memory.

9. A combination telephone and alphanumeric entry device unit, the combination unit comprising:

a keyboard having keys generating key signals when activated by a user, the keys including a page mode key;

a handset communicating audio messages between the user and the combination unit, the handset fitting within a cradle when not in use;

a handset switch providing a handset up signal indicating the handset has been removed from the cradle;

telephone line interface circuitry transferring telephone signals between the handset and the keyboard and a telephone line in a telephone mode and transferring paging signals between the keyboard and telephone line in a paging mode;

a microprocessor communicating with the interface circuitry, keyboard, handset switch, and operating according to a stored program to;

(i) cause the selection of the paging mode in response to a key signal indicating activation of the page mode key only if the handset up signal is not present;

(ii) cause the selection of the telephone mode in response to the handset up signal despite subsequent activation of the page mode key.

10. The combination telephone and alphanumeric entry device unit recited in claim 9 wherein the microprocessor operates according to the stored program to also:

(iii) cause the selection of the telephone mode in response to the handset up signal after selection of the paging mode unless the telephone line circuitry is transferring paging signals to the telephone line.
