ITU-T G.9960 (2015)/Cor.4 (03/2018) FOREWORD The International Telecommunication Union (ITU) is the United Nati

12、ons specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations

13、on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of

14、 ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is

15、 used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with

16、 the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required

17、 of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual

18、Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, im

Modifications introduced by this corrigendum are shown in revision marks relative to Recommendation ITU-T G.9960 (2015) plus its Corrigendum 1 (2015), Amendment 1 (2015), Corrigendum 2 (2016), Amendment 2 (2016) and Corrigendum 3 (2016). 1

29、 Scope This Recommendation specifies the system architecture and functionality for all components of the physical (PHY) layer of home network transceivers designed for the transmission of data over premises wiring, including inside telephone wiring, coaxial cable, power-line wiring, plastic optical

30、fibres, and any combinations of these. Specifically, this Recommendation defines: the home network architecture and reference models the physical layer specification (PCS, PMA and PMD). These transceivers are intended to be compatible with other devices sharing in-premises wiring. Additionally, this

31、 Recommendation provides for spectrum notching for compatibility with amateur radio services. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the

32、editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other references listed below.

37、s the following terms: 3.1 address association table (AAT): A table that associates the MAC addresses of the application entities with the DEVICE_ID of the nodes through which these application entities can be reached. 3.2 alien domain: Any group of non-ITU-T G.9960 nodes connected to the same mediu

38、m or which operate in close proximity. The bridging function to an alien domain, as well as coordination with an alien domain to avoid mutual interference is beyond the scope of this Recommendation. 3.3 bandplan: A specific range of the frequency spectrum that is associated with a domain. Multiple b

39、andplans may be used in the same domain provided that each bandplan used is a subset of the largest bandplan specified for the domain and a superset of the smallest bandplan specified for the domain. The bandplan is defined by a lower frequency and upper frequency except for RF, which is defined by

40、a bandwidth and centre frequency. 3.4 baseband: A frequency band defined by an up-convert frequency FUC = 0 and an up-shift frequency FUS = FSCN/2 (see Table 7-67). 3.5 bridge to alien domain/network: An application device implementing an L2 or L3 bridging function to interconnect an ITU-T G.9960 do

41、main to an alien domain (or alien network). Bridging to alien domains/networks is beyond the scope of this Recommendation. 3.6 broadcast: A type of communication where a node sends the same frame simultaneously to all other nodes in the home network or in the domain. 3.7 carrier sense (CRS): Generat

42、ed by the receiver, CRS indicates that the medium is busy, i.e., a PHY frame, or sequence of PHY frames, or a special signal (e.g., INUSE, PR) is currently transmitted on the medium by another node. CRS may be either a physical carrier sense signal or a virtual carrier sense indicator. Physical carr

43、ier sense is generated by analysing physical signals present on the medium. Virtual carrier sense is generated based on the information on the PHY frame duration or PHY frame sequence duration derived from the frame header or communicated to a node by other means (e.g., in another frame). 3.8 channe

44、l: A transmission path between nodes. One channel is considered to be one transmission path. Logically, a channel is an instance of a communication medium used for the purpose of passing data between two or more nodes. 3.9 coding overhead: A part of the overhead used to carry the coding redundancy (

45、such as redundancy bits of error correction coding or cyclic redundancy check (CRC). 3.10 crosstalk: Disturbance (including frame collision) introduced by or due to operation of alien networks or other (independent) ITU-T G.9960 home networks. 3.11 data: Bits or bytes transported over the medium or

46、via a reference point that individually convey information. Data includes both user (application) data and any other auxiliary information (overhead, including control, management, etc.). Data does not include bits or bytes that, by themselves, do not convey any information, such as the preamble. 3.

47、12 data rate: The average number of bits communicated (transmitted) in a unit of time. The usual unit of time for data rate is 1 second. Rec. ITU-T G.9960 (2015)/Cor.4 (03/2018) 3 3.13 DEVICE_ID: A unique identifier allocated to a node operating in the domain by the domain master during registration

48、. 3.14 domain: A part of an ITU-T G.9960 home network comprising the domain master and all those nodes that are registered with the same domain master. In the context of this Recommendation, use of the term “domain“ without a qualifier means “ITU-T G.9960 domain“, and use of the term “alien domain“

49、means “non-ITU-T G.9960 domain“. Additional qualifiers (e.g., “power-line“) may be added to either “domain“ or “alien domain“. 3.15 domain access point (DAP): The unique node in centralized mode (CM) that supports relay functionality through which all nodes communicate. 3.16 domain ID: A unique identifier of a domain. 3.17 domain master (DM): A node supporting the domain master functionality that manages (coordinates) all other nodes of the same domain
