No. A digital subscriber line (DSL) operates at layer 2 or the Data-link layer.
Physical, Data Link
It uses data modulation techniques at teh physical layer (layer 1).
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
Hubs are a physical layer (layer 1) device; most switches operate at the Data Link layer (Layer 2) of the OSI model.
Layer 3
Repeaters operate at the physical layer of the OSI model.
1. Repeaters (Operate at the OSI Physical Layer).2. Bridges (Operate at the OSI Data Link Layer).3. Routers {and Brouters} (Operate at the OSI Network Layer).
The NIC operates on Layer 2 (Data Link Layer) of the OSI Model.
Router works in Network Layer of OSI model
Network Layer
Layer 2 - Data Link
All layers.
Layer 5 - Session layer
