20、terface specifications for high-speed Data Over Cable Systems. The intended service will allow transparent bi-directional transfer of Internet Protocol (IP) traffic, between the cable system headend and customer locations, over an all-coaxial or Hybrid-Fibre/Coax (HFC) cable network. The transmissio
21、n path over the cable system is realized at the headend by a Cable Modem Termination System (CMTS), and at each customer location by a Cable Modem (CM). There are differences in the cable spectrum planning practices adopted for different networks in the world. Therefore two options for physical laye
22、r technology are included, which have equal priority and are not required to be inter-operable. One technology option is based on the downstream multi-programme television distribution that is deployed in North America using 6 MHz channelling, and supports upstream transmission in the region 5 MHz t
23、o 42 MHz. The other technology option is based on the corresponding European multi-programme television distribution and supports upstream in the region 5 MHz to 65 MHz. 4.3 Part 3: Baseline Privacy Plus Interface Specification ES 201 488-3 2, the Baseline Privacy Plus Interface (BPI+), describes MA
24、C layer security services for Data Over Cable Systems (DOCS) CMTS - CM communications. BPI+ security goals are twofold: provide cable modem users with data privacy across the cable network; and provide MSOs with service protection; i.e. prevent unauthorized users from gaining access to the networks
25、RF MAC services. BPI+ provides a level of data privacy across the shared medium cable network equal to or better than that provided by dedicated line network access services (analogue modems or digital subscriber lines). The protected radio frequency MAC data communications services fall into three
26、categories: best-effort, high-speed, IP data services; QoS (e.g. constant bit rate) data services; and IP multicast group services.
