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..
