A given headend may have between 1–12 CMTSs to service the cable modem population served by that headend or HFC hub. One way to think of a CMTS is to imagine a router with Ethernet interfaces (connections) on one side and coaxial cable RF interfaces on the other side. The Ethernet side is known as the Network Side Interface or NSI. [3] [4]
In Remote PHY, equipment such as CMTSs or CCAPs are connected directly to the HFC network using fiber optics carrying digital signals, eliminating the RF interface and coaxial cables at the CMTS/CCAP and RF modulation at the headend, [83] and replacing analog signals in fiber optic cables in the network, with digital signals such as 10 Gigabit ...
