where does information exchange begin in order to produce good customer service
Telephone exchange
Digital switches encode the speech going on , in 8,000 time slices per second . At each time slice , a digital PCM representation of the tone is made . The digits are then sent to the receiving end of the line , where the reverse process occurs , to produce the sound for the receiving phone . In other words , when someone uses a telephone , the speaker 's voice is `` encoded '' then reconstructed for the person on the other end . The speaker 's voice is delayed in the process by a small fraction of one second -- it is not `` live '' , it is reconstructed -- delayed only minutely . ( See below for more info . )
