Subscriber Asymmetric Digital Subscriber Line Modem of Asymmetric Digital Subscriber Line System

摘要

The present invention provides a subscriber side ADSL modem of an asymmetric digital subscriber line (ADSL) system, wherein a plurality of subscriber PC terminals can be connected to one ADSL modem using UTOPIA II communication between an ATM handler and an ATM transceiver. A subscriber side ADSL modem, comprising: a plurality of ATM transceivers for increasing the transmission rate of data and control signals processed by an ATM cell in an ATM handler or reducing the transmission speed of data and control signals transmitted from a subscriber PC terminal; The ATM transceiver is selected between a plurality of ATM transceivers and an ATM handler by using a UTOPIA II communication method. The ATM transceiver transmits and receives ATM cell data between the selected ATM transceiver and the ATM handler. Subscriber's ADS of ADSL system by sending / receiving ADSL service data using communication method Since multiple subscriber PC terminals can be connected to one L modem, many subscribers can simultaneously receive the desired ADSL service, and the cost of installing a new modem can be reduced.
