Integrated broadband cable telecommunication networks (CABLE) - Sixth generation transmission systems for interactive cable television services - IP cable modem - Part 2: Physical layer - DOCSIS® 4.0 [ANSI/SCTE 262-1 2020]

The present document provides the ETSI endorsement of ANSI/SCTE standard ANSI/SCTE 262-1 [1].
ANSI/SCTE 262-1 [1] is part of a series of standards that defines the sixth generation of high-speed data-over-cable
systems and is based on a set of specifications commonly referred to as DOCSIS 4.0 specifications. This generation of
the DOCSIS specifications builds upon the previous generations of DOCSIS specifications (commonly referred to as
the DOCSIS 3.1 and earlier specifications), leveraging the existing Media Access Control (MAC) and Physical (PHY)
layers. It includes backward compatibility for the existing PHY layers in order to enable a seamless migration to the
new technology. Further, the DOCSIS 4.0 specifications introduce Full Duplex (FDX) DOCSIS PHY layer technology
as an expansion of the OFDM PHY layer introduced in the DOCSIS 3.1 PHY specification to increase upstream
capacity without significant loss of downstream capacity versus DOCSIS 3.1. The DOCSIS 4.0 specification also builds
upon DOCSIS 3.1 OFDM and OFDMA technology with an extended Frequency Division Duplex (FDD) DOCSIS
alternative. DOCSIS 4.0 FDD supports legacy high split and also provides extended splits up to 684 MHz in an
operational band plan which is referred to as Ultra-High Split (UHS). DOCSIS 4.0 FDD also introduces expansion of
usable downstream spectrum up to 1 794 MHz. Both the FDX and FDD DOCSIS 4.0 alternatives are based on OFDM
PHY.
There are differences in the cable spectrum planning practices adopted for different networks in the world. For the
OFDM PHY layer defined in the present document, there is flexibility to deploy the technology in any spectrum plan;
therefore, no special accommodation for different regions of the world is required for this PHY layer.
However, due to the inclusion of the DOCSIS 3.0 PHY layers for backward compatibility purposes, there is still a need
for different region-specific physical layer technologies. Therefore, three options for physical layer technologies are
included in the present document, which have equal priority and are not required to be interoperable. One technology
option is based on the downstream channel identification plan that is deployed in North America using 6 MHz spacing.
The second technology option is based on the corresponding European multi-program television distribution. The third
technology option is based on the corresponding Chinese multi-program television distribution. All three options have
the same status, notwithstanding that the document structure does not reflect this equal priority. The first of these
options is defined in clauses 5 and 6 of [i.1], whereas the second is defined by replacing the content of those clauses
with the content of Annex C of [i.2]. The third is defined by replacing the content of those clauses with the content of
Annex D of [i.2]. Correspondingly, [13] and [i.3] apply only to the first option, and [4] applies to the second and third.
Compliance with the present document requires compliance with one of these implementations, but not with all three. It
is not required that equipment built to one option interoperates with equipment built to the other.
Compliance with frequency planning and EMC requirements is not covered by the present document and remains the
operators' responsibility. In this respect, [10] and [11] are relevant to the USA; [3] and [i.4] to Canada; [i.6], [5], [6],
[7], [8] and [9] are relevant to the European Union; [12] and [i.5] are relevant to China.
ANSI/SCTE 262-1 [1] defines the interface for the physical layer, and corresponds to the CableLabs specification
CM-SP-PHYv4.0-I02-200429 [i.1].

Integrirana širokopasovna kabelska telekomunikacijska omrežja (CABLE) - Šesta generacija prenosnih sistemov za storitve interaktivne kabelske televizije - IP-kabelski modemi - 2. del: Fizična plast - DOCSIS® 4.0 [ANSI/SCTE 262-1 2020]

Iz tega dokumenta je razvidno, da ETSI podpira standard ANSI/SCTE ANSI/SCTE 262-1 [1]. ANSI/SCTE 262-1 [1] je del skupine standardov, ki opredeljuje šesto generacijo sistemov hitrega prenosa podatkov prek kabelskega omrežja in temelji na nizu specifikacij, ki se običajno imenujejo specifikacije DOCSIS 4.0. Ta generacija specifikacij DOCSIS temelji na prejšnjih generacijah specifikacij DOCSIS (običajno imenovanih DOCSIS 3.1 in starejših), pri čemer izkorišča obstoječi nadzor dostopa do medijev (MAC) in fizične plasti (PHY). Vključuje povratno združljivost za obstoječe plasti PHY, kar omogoča enostaven prehod na novo tehnologijo. Poleg tega specifikacije DOCSIS 4.0 uvajajo tehnologijo sloja DOCSIS PHY Full Duplex (FDX) kot razširitev sloja OFDM PHY, uvedenega v specifikaciji DOCSIS 3.1 PHY za povečanje zmogljivosti »od uporabnika« brez znatne izgube zmogljivosti »do uporabnika« v primerjavi z DOCSIS 3.1. Specifikacija DOCSIS 4.0 temelji tudi na tehnologiji DOCSIS 3.1 OFDM in OFDMA z razširjeno alternativo DOCSIS Frequency Division Duplex (FDD). DOCSIS 4.0 FDD podpira podedovano visoko razcepitev in zagotavlja tudi razširjene razcepitve do 684 MHz v operativnem pasovnem načrtu, ki se imenuje Ultra-High Split (UHS). DOCSIS 4.0 FDD uvaja tudi razširitev uporabnega spektra »do uporabnika« do 1794 MHz. Obe možnosti FDX in FDD DOCSIS 4.0 temeljita na OFDM PHY. Med praksami načrtovanja kabelskega spektra, sprejetimi za različna omrežja po svetu, obstajajo razlike. Za plast OFDM PHY, opredeljeno v tem dokumentu, obstaja prilagodljivost za uvedbo tehnologije v kateri koli načrt spektra; zato za ta sloj PHY niso potrebne posebne prilagoditve za različne regije sveta. Vendar pa zaradi vključitve povratne združljivosti s plastjo DOCSIS 3.0 PHY še vedno obstaja potreba po različnih tehnologijah fizičnih plasti, specifičnih za regijo. Zato so za tehnologije fizične plasti v ta dokument vključene tri enakovredne možnosti, pri čemer ni treba, da so interoperabilne. Ena možnost temelji na načrtu identifikacije kanalov »do uporabnika«, ki se uporablja v Severni Ameriki in pri kateri imajo kanali razmik 6 MHz. Druga možnost temelji na ustrezni evropski večprogramski televizijski distribuciji. Tretja možnost temelji na ustrezni kitajski večprogramski televizijski distribuciji. Vse tri možnosti imajo enak status, čeprav struktura dokumenta ne odraža njihove enakovrednosti. Prva od teh možnosti je opredeljena v točkah 5 in 6 [i.1], druga pa z zamenjavo vsebine omenjenih točk z dodatkom C [i.2]. Tretja možnost je opredeljena z zamenjavo vsebine omenjenih točk z dodatkom D [i.2]. Skladno s tem [13] in [i.3] veljata le za prvo možnost in [4] velja za drugo in tretjo možnost. Skladnost s tem dokumentom pomeni skladnost z eno opisano izvedbo in ne z vsemi tremi. Interoperabilnost opreme, izdelane v skladu z eno možnostjo, z opremo, izdelano v skladu z drugo možnostjo, ni zahtevana. Skladnost z načrtovanjem frekvence in zahtevami elektromagnetne združljivosti v tem dokumentu ni obravnavana ter ostaja v odgovornosti operaterjev. V zvezi s tem [10] in [11] veljata za Severno Ameriko, [3] in [i.4] za Kanado, [i.6], [5], [6], [7], [8] in [9] veljajo za Evropsko unijo, [12] in [i.5] veljata za Kitajsko. ANSI/SCTE 262-1 [1] določa vmesnik za fizični sloj in ustreza specifikaciji CableLabs CM-SP-PHYv4.0-I02-200429 [i.1].
