20、ervice 4 Overview of the multi-part ETSI standard 4.1 Part 1: General The present document. 4.2 Part 2: Radio frequency interface specification ES 202 488-2 1 defines the radio-frequency interface specifications for high-speed second generation IP cable modem systems. The intended service will allow
21、 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 transmission path over the cable system is realized at the headend by a Cable Modem Termination System (C
22、MTS), 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 definitions for physical layer technology are included in this specification, which have equal priority and are not req
23、uired to be inter-operable. One technology definition is based on the downstream multi-programme television distribution that is deployed using 6 MHz channelling, and supports upstream transmission in the region 5 MHz to 42 MHz. The other technology definition is based on the corresponding downstrea
24、m multi-programme television distribution that is deployed using 8 MHz channelling, and supports upstream transmission in the region 5 MHz to 65 MHz. It is the network operators choice of which technology definition to deploy. 4.3 Part 3: Baseline privacy plus interface specification ES 202 488-3 2,
25、 the Baseline Privacy Plus Interface (BPI+), describes MAC layer security services for Second Generation IP Cable Modem Systems 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
26、. prevent unauthorized users from gaining access to the networks 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
27、radio frequency MAC data communications services fall into three categories: best-effort, high-speed, IP data services; QoS (e.g. constant bit rate) data services; and IP multicast group services.
