Chapter 4 Understanding and Configuring Digital Voice Ports
Digital voice ports, unlike analog voice ports, have the unique capability to carry multiple simultaneous conversations on the same circuit. Therefore, in installations with multiple circuits (about seven or more), the economies of scale offered by digital voice ports start to make digital voce ports more economically attractive that multiple analog ports.
Digital Voice-Port Theory
Although analog ports send and receive analog waveforms that continually vary, digital ports send binary data (that is, binary 1s/0s), which are represented on the wire as the presence of voltage or the absence of voltage. Examples of digital circuits include T1, E1, and Integrated Services Digital Network ...
