    Provide cable modem users with data privacy across the cable network; Provide cable service operators with service protection (i.e. prevent unauthorized modems and users from gaining access to the network's RF MAC services) BPI/SEC is intended to prevent cable users from listening to each other.

  3. Cable Internet access - Wikipedia

    en.wikipedia.org/wiki/Cable_Internet_access

    In telecommunications, cable Internet access, shortened to cable Internet, is a form of broadband internet access which uses the same infrastructure as cable television. Like digital subscriber line and fiber to the premises services , cable Internet access provides network edge connectivity ( last mile access) from the Internet service ...

    802.11 networks in infrastructure mode are half-duplex; all stations share the medium. In infrastructure or access point mode, all traffic has to pass through an Access Point (AP). Thus, two stations on the same access point that are communicating with each other must have each and every frame transmitted twice: from the sender to the access ...

    en.wikipedia.org/wiki/Passive_optical_network

    Data Over Cable Service Interface Specification Provisioning of Ethernet Passive Optical Network, or DPoE, is a set of CableLabs specifications that implement the DOCSIS service layer interface on existing Ethernet PON (EPON, GEPON or 10G-EPON) media access control (MAC) and physical layer (PHY) standards. In short it implements the DOCSIS ...

  7. Cable modem - Wikipedia

    en.wikipedia.org/wiki/Cable_modem

    In network topology, a cable modem is a network bridge that conforms to IEEE 802.1D for Ethernet networking (with some modifications). The cable modem bridges Ethernet frames between a customer LAN and the coax network. Technically, it is a modem because it must modulate data to transmit it over the cable network, and it must demodulate data ...

  8. Cable modem termination system - Wikipedia

    en.wikipedia.org/wiki/Cable_modem_termination_system

    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]

  9. Hybrid fiber-coaxial - Wikipedia

    en.wikipedia.org/wiki/Hybrid_fiber-coaxial

    The very first HFC networks, and very old unupgraded HFC networks, are only one-way systems. Equipment for one-way systems may use POTS or radio networks to communicate to the headend. [103] HFC makes two-way communication over a cable network practical because it reduces the number of amplifiers in these networks. [1]
