25、nt, the terms and definitions given in EG 201 730-1 4 and the following apply: Cable Modem Termination System (CMTS): located at the cable television system headend or distribution hub, which provides complementary functionality to the cable modems to enable data connectivity to wide-area network se
26、rvices Cable Modem Termination System - Network Side Interface (CMTS-NSI): interface, between a CMTS and the equipment on the access network side direct access: access for TE to services provided by a PNO or PSP exclusively via the infrastructure of that PNO or PSP Distribution Hub: location in a ca
27、ble television network which performs the functions of a Headend for customers in its immediate area, and which receives some or all of its television program material from a Master Headend in the same metropolitan or regional area headend: central location on the cable network that is responsible f
28、or injecting broadcast video and other signals in the downstream direction NOTE: See also Master Headend, Distribution Hub. indirect access: access for TE to services provided by a PNO or PSP via the infrastructure of another PNO or PSP master headend: headend which collects television program mater
29、ial from various sources by satellite, microwave, fibre and other means, and distributes this material to Distribution Hubs in the same metropolitan or regional area NOTE: A Master Headend may also perform the functions of a Distribution Hub for customers in its own immediate area. Network Equipment
30、 (NE): equipment forming the Public Operators Network up to and including NTP, relevant for the provision of Telecommunications services Open Systems Interconnection (OSI): framework of ISO standards for communication between different systems made by different vendors, in which the communications p
31、rocess is organized into seven different categories that are placed in a layered sequence based on their relationship to the user NOTE: Each layer uses the layer immediately below it and provides a service to the layer above. Layers 7 through 4 deal with end-to-end communication between the message
32、source and destination, and layers 3 through 1 deal with network functions. Public Telecommunications Network (PTN): Telecommunications Network used to provide publicly available Telecommunications Services Radio Frequency (RF): in cable television systems, this refers to electromagnetic signals in
33、the range 5 MHz to 1 000 MHz Telecommunication Terminal Equipment (TE): according to R in accordance with Article 17 of Directive 2002/21/EC“.
