What layer or layers of the OSI 7-layer model does ADSL fulfil?

anyone help?

Is this your homework? Nobody talks about the OSI 7-layer model except in networking classes.

ADSL consists of the bottom two layers, the physical layer (in this case, phone lines) and the data link layer (the ADSL standards for packet transmission, etc.) Layers 3 and above are dependent on what kind of network protocols and applications you want to run (usually TCP/IP nowadays).

Couldn't have said it better...
Physical layer deals with bits, and is primarily the hardware involved in moving the bits.
The data link layer is concerned with establishing a connection between the hardware pieces.
ADSL is the technology used to make the connection from one end to the other ie, your home to the internet provider's server.
