Automatic Number Identification (ANI)
Automatic Location Information (ALI)
What is CAD?
Computer Aided Dispatch systems
Phone system where fluctuating sound waves from a caller's voice cause vibration in the telephone's transmitter, these vibrations trigger electrical signals that vary in frequency and strength...at the other end the process is reversed as the receiver generates vibrations that re-create the voice.
Phone system where sound converted to a series of pulses that encode the information and put back together when it’s received.
Transmission lines that allows many signals to be transmitted across one medium. It works by routing each call on a different electrical frequency.
