Intellectual Property Rights
IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://ipr.etsi.org).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Powerline Telecommunications
(PLT).
Introduction
The present document specifies a high-performance narrow band power line channel for control networking in the smart
grid that operates in the EN 50065-1 [2] 9 kHz to 95 kHz sub-band ("A band") and is compatible with the CEN
EN 14908 Open Data Communication in Building Automation, Controls and Building Management Control
Networking standard and other protocols. The present document is suitable for smart grid applications such as, but not
limited to, smart metering, distribution line management, distributed generation, electric vehicle charging and demand
response.
This channel definition does not include built-in support for co-existence of dissimilar transceiver types at the
PHY/MAC layer. Sharing of the media with other dissimilar technologies, for example, by segmenting access time to
the channel or adjusting the duty cycle, is the responsibility of upper levels of protocols that make use of the present
document.

1 Scope
The present document contains all the information necessary to facilitate the exchange of data and control information
over the power line medium between devices that share the same LV transformer(s) within a utility's electricity
network.
Certain aspects of the present document are defined in other documents. These documents are referenced where
relevant. In the case where a referenced standard conflicts with the present document, the present document will prevail.
The present document provides the necessary adaptions to the endorsed document [1].
The present scope replaces in its entirety the scope of the endorsed document [1].

Clause 5.2 "Data Channel"
Shall be modified as follows:
The channel occupies the 125 kHz to 140 kHz 9 kHz to 95 kHz frequency band, as defined in EN 50065-1, as a Binary
Phase Shift Keyed (BPSK) modulated carrier. This channel is used to send protocol messages containing control, status,
configuration and diagnostic information. The signalling characteristics of the channel are descr
