What is a Digital Modem?
| Digital Modems |
|
A system component which allows communication over digital access facilities with a remotely located system connected to the public network over analog facilities. Converts incoming digital data stream containing PCM-encoded modem waveform into actual data contained in waveform at data rate transmtted by far-end modem; performs inverse function for outgoing data stream. Traditional phone service connects your home or business to a telephone company office over copper wires that are wrapped around each other. The wires are called twisted pair. The digital modem, which may be purchased or rented, -- located at your location -- accesses the local telephone companies' central office where a Digital Subscriber Line Access Multiplexer, which translates your DSL signal, has been installed. The signal is then transmitted from the copper telephone line onto a network backbone, and directed to the ISP's location, where the ISP verifies the access to the network and delivers users to the Internet through the ISP's relationship with a backbone network provider. |
