Often too many people get confused with all the definitions, here we have explained in easy to understand terms.
ADSL:
Asymmetric Digital Subscriber Line - asymmetric meaning it's faster downstream than upstream.
ASAM:
Advanced Services Access Manager -Whether you have a DSLAM or ASAM in your exchange doesn't really matter. They do the same thing. See DSLAM's as well.
ATM:
Asynchronous Transfer Mode - a method of encapsulation which is capable of many virtual circuits. With these, providers (ISP's) can split an ATM connection (155Mbit or 622Mbit) up into many connections. ATM isn't just used for DSL but in the case of DSL it's used to provision each customer.
