Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Access, Terminals, Transmission
and Multiplexing (ATTM).
The present document is part 4 of a multi-part deliverable covering the External Common Power Supply 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";

Introduction
The present document is part of a multi-part deliverable covering External Common Power Supply (CPS) for Customer
Premises Network and Access Equipment.
This 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 [i.1] defines functional requirements for four different categories of CPS.
• TS 102 874-2 [i.2] defines detailed implementation and operational aspects for CPS Type 2.a.
• TS 102 874-3 [i.3] defines detailed implementation and operational aspects for CPS Type 1.
• TS 102 874-4 (the present document) defines detailed implementation and operational aspects for CPS
Type 2.b.
• TS 102 874-5 [i.4] defines detailed implementation and operational aspects for CPS Type 2.c.
The intended applications of these CPS categories are specified in ES 202 874-1 [i.1].

The present document addresses the implementation details of the External Common Power Supply (CPS) for Customer
Premises Network and Access Equipment - Type 2.b, rated to a maximum of 12V dc and a maximum current of 2Amp
for use with CPEs, set top boxes and other customer network devices with similar power needs.
Other methods for providing power to end devices are not in the scope of the document (e.g. Power Over Ethernet,
power on USB, etc.).
Test are specified to verify the compliance of the external power supply against the requirements given by the present
specification.
The present document specifies design requirements and tests to ensure compliance of the CPS as well as reference to
relevant European Directives including power efficiency on-load and no-load requirements given by European
Commission Regulation No 278/2009 of 6 April 2009 [1].

1 Scope
The present document describes the specification for a high performance External Power Supply Unit for powering the
Customer Premises Equipment to a maximum voltage rating of 12V dc.
The specifications define the input, output characteristics and performance requirements for a switching mode AC to
DC CPS rated to a maximum 12V dc, and maximum 2 A.
The present document also specifies tests to verify the compliance of the external CPS.
