Foreword This ETSI Standard (ES) has been produced by ETSI Technical Committee Access, Terminals, Transmission and Multiplexing (ATTM). The present document is part 1 of a multi-part
15、deliverable covering the External Common Power Supply (CPS) for Customer Premises Network and Access Equipment, as identified below: ES 202 874-1: “Functional requirements“; TS 102 874-2: “Integrated Broadband Cable and Television Networks“; TS 102 874-3: “CPS Type 1 implementation details“; TS 102
16、874-4: “CPS Type 2.b implementation details“; TS 102 874-5: “CPS Type 2.c implementation details“; TS 102 874-6: “CPS Type 2.d implementation details“. Introduction The present document addresses the functional requirements and implementation and operational aspects of the External Common Power Supp
17、ly (CPS) for Customer Premises Network and Access Equipment. The multi-part deliverable represents a set of cohesive interwoven technical information that has jointly evolved to define solution of most efficient equipment, as defined below: ES 202 874-1 defines functional requirements for four diffe
18、rent categories of CPS. TS 102 874-2 i.1 defines detailed implementation and operational aspects for CPS Type 2.a. TS 102 874-3 i.2 defines detailed implementation and operational aspects for CPS Type 1. TS 102 874-4 i.3 defines detailed implementation and operational aspects for CPS Type 2.b. TS 10
19、2 874-5 i.4 defines detailed implementation and operational aspects for CPS Type 2.c. TS 102 874-6 i.7 defines detailed implementation and operational aspects for CPS Type 2.d. The intended applications of these CPS categories are specified in the present document. ETSI ETSI ES 202 874-1 V1.2.1 (201

21、102 874-5 i.4 Type 2.d: 12 V, 3,2 A TS 102 874-6 i.7 The present document is describing functional requirements applicable to an external common power supply (CPS) converting and adapting AC mains to DC power for customer premises network equipment. Other methods for providing power to end devices a
22、re not in the scope of the present document (e.g. Power Over Ethernet, power on USB, etc.). The requirements were defined on the basis of HGI (Home Gateway Initiative) activity on the same subject contained in the public document HGI-RD015-R3 i.5. That is the result of collaborative efforts of HGI m
23、embers that include Broadband Service Providers (BSPs), gateway manufacturers, and silicon vendors. The present document is defining operating conditions, energy efficiency and ecodesign aspects for a number of categories of power supplies, depending on market applicability and power needs of the ta
24、rgeted Customer Premises Equipment (CPEs). Additional Technical Specifications will address the implementation aspects for each of the CPS categories here defined, including the choice of connectors. The need for standardization activities in energy efficiency and ecodesign related to telecommunicat
25、ions is now widely seen. For example the European Union, in the “ICT 2009 Standardization Work Programme“ i.6 highlights this need. Enabling the use of standardized power supplies, or the development of a new Common Power Supply (CPS) for DSL modems, home gateways, optical network terminations is a
26、key aspect of telecommunications standardization that will contribute to ecodesign. The expected timeline for adoption of the present document is as follows: Initial, partial deployments prior to 2011 depending on availability of specific TSs. Universal deployments for customer premises equipment wi
27、thin service providers networks (i.e. within those service providers mandating these requirements) starting from 2011. ETSI ETSI ES 202 874-1 V1.2.1 (2012-05)61 Scope and Purpose 1.1 Scope The present document specifies a universal solution for power supplies (named Common Power Supply and indicated
28、 with the acronym CPS) suitable for customer equipment used in the home networks, using energy provided by mains power in a range between 100 V and 240 V AC and 50 Hz to 60 Hz of frequency (apart tolerances). The topics addressed in the present document are as follows: applicability: definition of p
29、roduct categories included in the scope (home gateway, and various other devices installed in the home network); market scenarios and use cases for the use of the CPS in the home environment; functional requirements for electrical operating conditions of the CPS; functional requirements for energy e
30、fficiency of the CPS; functional requirements for connectors on the CPS and devices which it powers; functional requirements for eco-design of the CPS. 1.2 Applicability Customer Network Gateway (CNG) Power Supply Customer Network Gateways, also called Home gateways, currently use external power sup
31、plies (“bricks“) that provide different ranges of output voltage and current. Furthermore, the connectors on the HG which attach to the power supply, and the corresponding connectors on the cable frequently differ, not only between HGs of different vendors, but also between different HG models from
32、the same vendor. A suitable output voltage and current, along with connector type would have to be specified to create a truly “universal“ solution applicable to all home gateways. Home Network Infrastructure Devices (HNIDs) Power Supply In addition to home gateways, other home network infrastructur
33、e devices (HNIDs) may use a power supply with similar features in terms of voltage and current, so that a common solution could be defined for both types of device. These HNID devices may have a similar specification and distribution process, in other words they are managed and/or supplied by a comm
34、on BSP. Therefore, the extension of the CPS solution defined for HGs to HNIDs has also been considered. End Device Power Supply Some end user devices use power supplies with similar characteristics to those of CNGs (e.g. some set top boxes, cordless phones and IP phones). The requirements contained
35、in the present document apply to all the above mentioned categories. 1.3 Requirements Notation If the present document is implemented, the key words “MUST“ and “SHALL“ as well as “REQUIRED“ are to be interpreted as indicating a mandatory aspect of the present document.
