Abstract

A telephone call handling system for use with key telephone systems, including means for displaying at a called extension the identification number of the line on which the incoming call is received. A receptionist enters extension and line identification data by means of a key pad or dial, thereby causing corresponding electrical signals to be generated. An address network responds to the extension identification signal to transmit the line identification signal to the called extension. A digital display at the called extension indicates the line on which the incoming call is received, and a buzzer produces an audible signal at the called extension, in response to received line identification data.

Claims

1. Apparatus for use in conjunction with a key telephone system for handling incoming calls, comprising:

a a plurality of digital readouts each associated with an extension of said key system, said digital readouts for visual display of data indicating the line on whIch an incoming call is received; and

b means for receiving extension and line data corresponding to an incoming call and for transmitting the line data for display by the digital readout associated with the extension corresponding to the received extension data.

2. Apparatus according to claim 1, wherein said last named means includes the dial or keyboard of one telephone of the key telephone system and means connected thereto for generating and transmitting electrical data pulses.

3. Apparatus according to claim 1, wherein said last named means includes an auxiliary dial or keyboard and means connected thereto for generating and transmitting electrical data pulses.

4. An extension and line indicating system for use in conjunction with a key telephone system for handling incoming calls, comprising:

a input means for entry of data signifying the called party'"'"''"'"'s extension and the line on which the call is received;

b signal generating means operably connected to said input means, for producing in response thereto an extension identification signal and a line identification signal;

c a plurality of display means each associated with an extension telephone of said key telephone system, said display means for providing a visual indication of the telephone line corresponding to line identification signals received thereby; and

d transmission means in communication with said signal generating means and said plurality of display means, for transmitting line identification signals to the display means associated with the extension corresponding to a received extension identification signal.

5. Apparatus according to claim 4, wherein said display means includes a digital readout mounted on an extension telephone of said key telephone system so that the digital readout is visible on the face of the telephone.

6. Apparatus according to claim 4 further including a plurality of audible signaling devices each associated with an extension telephone of said key telephone system, said audible signaling devices connected to said display means and operable to produce an audible signal on receipt of line identification signals.

7. Apparatus according to claim 4 further including digital display means connected to said signal generating means and associated with said input means for displaying the extension and line data for confirmation purposes.

8. A line indicating system for use in conjunction with a key telephone system for handling of incoming calls, comprising:

a input means for the entry of the number of the called party'"'"''"'"'s extension and the identifying number of the line on which the incoming call is received;

b pulse generating means operatively connected to said input means for generating a first set of pulses corresponding to the called extension number and a second set of pulses corresponding to the identifying number of the line;

c a plurality of display means each associated with a separate extension of said key system and operable when addressed to visually display a received line identifying number; and

d address means operatively connected to said pulse generating means and to said plurality of display means for pulse transmission therebetween, said address means for directing said second set of pulses to one of said plurality of display means associated with the extension corresponding to said first set of pulses, whereby the identifying number of the called line is caused to be displayed at the called party'"'"''"'"'s extension.

9. Apparatus according to claim 8, wherein said input means comprises a dial or keyboard of one telephone of the key telephone system and switching means for alternatively connecting the dial or keyboard to a central office line or to said pulse generating means.

10. Apparatus according to claim 8, wherein said input means comprises an auxiliary dial or keyboard associated with one telephone of the key telephone system.

11. Apparatus according to claim 8 further includIng display means associated with said input means and connected to said pulse generating means for displaying the extension and line identifying numbers.

12. Apparatus according to claim 8 further including audible signaling devices associated with said display means for producing an audible signal when line identifying pulses are received at the extension.
