Abstract

Voice recording apparatus includes full duplex communication between the operator`s telephone set and the PBX switching matrix, and digital signal recording circuitry, for selectably presenting the operator'"'"'s actual voice or the recorded voice message to the PBX in response to operator selection.

Claims

1. Apparatus for exchanging voice information between a PBX operator'"'"'s microphone and receiver and a PBX switching matrix, comprising:

analog signal input/output (I/O) interface means responsive to the operator'"'"'s microphone and to the PBX switching matrix, for presenting voice signals from the PBX switching matrix to the operator'"'"'s receiver and for presenting voice signals from the operator'"'"'s microphone and recorded voice messages from a signals recording means to the PBX switching matrix;

said analog signal input/output (I/O) interface means comprising signal conditioning circuitry including signal summing means responsive at each of two inputs to actual voice signals from the operator'"'"'s microphone and to recorded voice messages from said signal recording means, for presenting each of said voice signals to the PBX switching matrix;

said analog signal input/output (I/O) interface means including means to provide full duplex exchange of voice signals between said PBX switching matrix and the operator'"'"'s microphone and receiver;

mode switch means, operable in a first mode and a second mode, alternately, in response to operator selection;

actuating switch means, operable in an off state and on statge, alternately, in response to operator selection;

signal recording means, responsive to said mode switch means, said actuating switch means, and to said analog signal input/output (I/O interface means, for message recording the operator'"'"'s voice signals in response to said mode switch means being in said first mode in the presence of said actuating switch means being in said on state, and for presenting said recorded messages to said analog signal input/output (I/O) interface means in response to said mode switch means being in said second mode in the presence of said actuating switch means being in said on state.

2. Apparatus for exchanging voice information between a PBX operator'"'"'s microphone and receiver and a PBX switching matrix, comprising:

analog signal input/output (I/O) interface means, responsive to the operator'"'"'s microphone and to the PBX switching matrix, for presenting voice signals from the PBX switching matrix to the operator'"'"'s receiver and for presenting voice signals from the operator'"'"'s microphone and recorded voice messages from a signal recording means to the PBX switching matrix;

6. The apparatus of claim 2, wherein said codec signal means comprises circuitry for delta modulation encoding.

7. The apparatus of claim 2, wherein said codex signal means comprises circuitry for adaptive delta modulation encoding.

8. The apparatus of claim 2 wherein:

said memory means for storing signals comprises dynamic random access memory means, each responsive to memory refresh signals presented periodically thereto for maintaining in storage said digital recording signals; and

said signal processing means includes program memory means for storing program operating signals for controlling said signal processing means in the operation of said digital signal recording means, said program operating signals including said memory refresh signals for providing said memory refresh signals periodically to siad dynamic random access memory means.

3. mode switch means, operable in a first mode and a second mode, alternately, in response to operator selection;

4. actuating switch means, operable in an off state and on state, alternately, in response to operator selection;

5. signal recording means, responsive to said mode switch means, said actuating switch means, and to said analog signal input/out, (I/O) interface means, for message recording the operator'"'"'s voice signals in response to said mode switch means being in said first mode in the presence of said actuating switch means being in said on state, and for presenting said recorded messages to said analog signal input/output (I/O) interface means in response to said mode switch means being in said second mode in the presence of said actuating switch means being in said on state;

said signal recording means comprising codec signa means for encoding operator analog voice signals from said analog signal input/output (I/O) interface means into equivalent digital recording signals in the presence of said mode switch means in said first mode, and for decoding digital recording signals from a digital signal recording means into equivalent operator analog voice signals at said analog signal input/output (I/O) interface means in the presence of said mode switch means in said second mode; and

, digital signal recording means, responsive to said digital recording signals, and including signal processing means and memory means for storing signals, said signal processing means responsive to said mode switch means and said actuating switch means, for storing in said memory means said digital recording signals from said codec means in response to said mode switch means in said first mode in the presence of said actuating switch means in said on state, and for retrieving and presenting to said codec means said digital recording signals stored in said memory means in response to said mode switch means in said second mode in the presence of said actuating switch means in said on state.
