ABSTRACT:
A DSL communication method and apparatus provides mutual communications between a user-site DSL modem and a provider-site router by using an existing two-wire telephone line and an existing DSL communication technology. In the DSL modem, a plurality of virtual channel values are correlated to a PPP connection between the modem and the router. Input IP data is received and the IP data is output according to a priority class defined for a sender IP data contained in the input IP data. An ATM cell is generated in which one of the plurality of virtual channel values corresponding to the sender IP data of the input IP data is assigned to the output IP data. The resulting ATM cell is transmitted from the modem to a DSL circuit connected to the router.
