WebISDN. In ISDN terminology, the terminal adapter connects a terminal (computer) to the ISDN network. The TA therefore fulfills a similar function to the ones a modem has on the POTS network, and is therefore sometimes called an ISDN modem.The latter term, however, is partially misleading as there is no modulation or demodulation performed.. There are … WebModulation Changing the carrier signal so that it can represent data during transmission over analog media is called modulation. Recalling from an earlier chapter, the waveforms of signals have three defining attributes: amplitude, frequency, and phase. ...
