ITU-T G.9960 (2015)/Cor.1 (11/2015) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardiz
12、ation Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which m
13、eets 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 ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-T
14、s purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation i
15、s voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“
16、 and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may i
17、nvolve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this R
18、ecommendation, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at

27、 Recommendation ITU-T G.9960 Unified high-speed wireline-based home networking transceivers System architecture and physical layer specification Corrigendum 1 Editorial note: Modifications introduced by this corrigendum are shown in revision marks. 1 Scope This Recommendation specifies the system ar
28、chitecture 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 fibres, and any combinations of these. Specificall
29、y, 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 Recommendation provides for spectrum notching for
30、 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 editions indicated were valid. All Recommendations
31、 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.

35、5) 3 Definitions This Recommendation defines 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
36、-T G.9960 nodes connected to the same medium 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 t
37、hat is associated with a domain. Multiple bandplans 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 fr
38、equency except for RF, which is defined by 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
39、function to interconnect an ITU-T G.9960 domain 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 t
40、he domain. 3.7 carrier sense (CRS): Generated 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 vir
41、tual carrier sense indicator. Physical carrier 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
42、 means (e.g., in another frame). 3.8 channel: 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 ove
43、rhead used to carry the coding redundancy (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: Bi
44、ts or bytes transported over the medium or 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 conve
45、y any information, such as the preamble. 3.12 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. 3.13 DEVICE_ID: A unique identifier allocated to a node operating in the domain by the domain master during registration
46、. Rec. ITU-T G.9960 (2015)/Cor.1 (11/2015) 3 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 d
47、omain“, and use of the term “alien domain“ 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
48、 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 (i.e., assigns bandwidth resources and manages priorities). Only one active domain master is allowed
49、 in a domain, and all nodes within a domain are managed (coordinated) by a single domain master. If a domain master fails, another node of the same domain, capable of operating as a domain master, should pick up the function of the domain master. 3.18 flow: A unidirectional stream of data between two nodes related to a specific application and/or characterized by a set of QoS requirements. 3.19 FLOW_ID: An identifier allocated to a
