Configuring the MAC Interface
Media Access Control (MAC) is a logical interface implemented within
hardware and software. MAC contains one downstream and four upstream
channels. Frequencies are assigned for each of the downstream and
upstream channels.
MAC interface parameters are associated with DOCSIS/EuroDOCSIS module
timing and control features that exist at network layer 2 to manage
upstream and downstream traffic.
