Question

Which Open Systems Interconnection (OSI) reference model layers does the MAC Layer in the Data Over Cable Service Interface Specification (DOCSIS) overlap?

Answer 1

The MAC Layer in DOCSIS overlaps with the Data Link Layer and Physical Layer of the OSI reference model.

Step-by-step explanation:

The MAC Layer in DOCSIS (Data Over Cable Service Interface Specification) overlaps with two layers of the OSI reference model.

The MAC Layer primarily functions at the Data Link Layer (Layer 2) of the OSI model. It is responsible for managing access to the physical network medium, addressing, and error detection.

Additionally, the MAC Layer also has some elements that overlap with the Physical Layer (Layer 1) of the OSI model. The physical signaling of DOCSIS, such as modulation schemes and frequency bands used, is determined by the MAC Layer specifications.
