Real Time Measurement Of Network Delay

A system comprising:

• a tone generator configured to provide a first tone of a determined frequency;
• a telephone configured to receive said first tone and generate a first signal corresponding to said first tone over an established telephone connection;
• a telephone switch configured to receive said first signal and generate a digitized data representing said first signal;
• a gateway receiving said digitized data and forming packets conveying said digitized data;
• a work station operatively connected to a speaker and microphone, said workstation receiving said packets from said gateway and providing a second signal thereby causing rendering of a second tone using said speaker;
• and
• an oscilloscope receiving said first signal on a first input and the second signal and providing an indication of the time between said first signal and said second signal.

A method comprising the steps of:

• establishing a telephone connection from a telephone to a workstation by dialing a telephone number associated with the provision of an operator service;
• generating a tone received by said telephone after the establishment of the telephone connection, thereby causing an first signal to be generated by the phone to a telephone switch;
• receiving said first signal at a first input of an oscilloscope;
• conveying a first plurality of digitized signals representing said tone from said telephone switch to a gateway;
• processing said first plurality of digitized signals at said gateway so as to form a first set of packets conveying said digitized signals;
• transmitting said first set of packets to a workstation;
• processing said first set of packets at said workstation so as to cause a second signal to be generated, said second signal used by said workstation to generated a second tone using a speaker;
• and
• receiving said second signal at a second input of the oscilloscope.
