Questions tagged [adsl]

Asynchronous Digital Subscriber Line is a layer 1 networking protocol, typically used for last mile Internet access. It utilises standard telephone cabling and coexists with analogue telephones. An ADSL modem at the customer premises communicates with the DSLAM at the local exchange. ATM is usually used as the layer 2 protocol, with PPPoE or PPPoA used for authentication.
