21、ble networks including equipment and associated methods of measurement for headend reception, processing and distribution of television and sound signals and for processing, interfacing and transmitting all kinds of data signals for interactive services using all applicable transmission media. These
22、 signals are typically transmitted in networks by frequency-multiplexing techniques. This includes for instance: a) regional and local broadband cable networks; b) extended satellite and terrestrial television distribution systems; c) individual satellite and terrestrial television receiving systems
23、; and all kinds of equipment, systems and installations used in such cable networks, distribution and receiving systems. The extent of this standardization work is from the antennas and/or special signal source inputs to the headend or other interface points to the network up to the terminal input o
24、f the customer premises equipment. The standardization work will consider coexistence with users of the RF spectrum in wired and wireless transmission systems. The standardization of any user terminals (i.e. tuners, receivers, decoders, multimedia terminals etc.) as well as of any coaxial, balanced
25、and optical cables and accessories thereof is excluded.

26、uipment and cable distribution systems of broadcast DVB-T and DVB-T2 signals in the VHF and UHF bands. While primarily intended to be used with VHF/UHF DVB-T and DVB-T2 receivers and signal distribution systems, filters can also be useful for mitigation of interference to VHF FM or DAB radio. 2 Norm

In all cases th
35、e stop-band lies above the pass-band. 4.2 Pass-band and stop-band of a LTE filter (800 MHz band) Pass-band (terrestrial broadcasting service): a) the lower boundary of the pass-band shall lie between 0 Hz (DC) and 174 MHz; b) the upper boundary of the pass-band shall lie on the upper edge of a TV ch
36、annel, UHF channel N, such that the pass-band upper bound frequency is (8*N+310) MHz. The value of N shall be in the range 58 to 60. It should be noted that a filter of the band-stop (or band-reject) type can be used to meet this specification. Where this type of filter is used, the range of frequen
37、cies lying above the defined stop-band is not considered to be part of the pass-band for the purpose of this specification. NOTE 1 What the filter does above 862 MHz might be advantageous and could offer some roll-off in the 900 MHz mobile spectrum, but this is outside the scope of this specificatio
38、n. Stop-band: shall be from 791 MHz to 862 MHz, divided in two parts: 1) Stop-band 1: 791 MHz to 821 MHz (LTE Base Station (LTE-BS) 2) Stop-band 2: 832 MHz to 862 MHz (LTE User Equipment (LTE-UE) NOTE 2 It is intended to add an extended stop-band option in a future revision of this specification, al
39、lowing the option to cover the proposed 700 MHz LTE band once the extent of that band is agreed.

40、ned below. a) Standard 1 LTE filter “Professional” filter for use in large cable systems incorporating distribution amplifiers and/or where greater attenuation of LTE interference is required in the case that channel 60 is not distributed. b) Standard 2 LTE filter “Consumer” filter intended for use
41、with a single receiver or a number of receivers fed via a passive distribution network. c) Standard 3 LTE filter “Typical” filter for use in MATV systems incorporating distribution amplifiers and/or where a typical attenuation for LTE interference mitigation is required. 4.4 LTE filter specification
