Foreword
This European Telecommunication Standard (ETS) has been prepared by the Network Aspects (NA)
Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS details the Protocol Implementation Conformance Statement (PICS) for the Physical Layer
Convergence Procedure (PLCP) for a European Metropolitan Area Network (MAN) based on the
Distributed Queue Dual Bus (DQDB) access method as defined in ETS 300 212 [2] operating at a
transmission rate of 139,264 Mbit/s in accordance with ETS 300 215 [1].

1 Scope
This European Telecommunication Standard (ETS) defines Protocol Implementation Conformance
Statement (PICS) for the Physical Layer Convergence Procedure (PLCP) at 139,264 Mbit/s for use in the
context of a subnetwork of a Metropolitan Area Network (MAN) as defined in ETS 300 215 [1].
2 Normative references
This ETS incorporates, by dated or undated reference, provisions from other publications. These normative
references are cited at the appropriate places in the text and the publications are listed below. For dated
references, subsequent amendments to or revisions of these publications apply to this ETS only when
incorporated in it by amendment or revision. For undated references the latest edition of the publication
referred to applies.
[1] ETS 300 215: "Network Aspects (NA); Metropolitan Area Network (MAN)
Physical layer convergence procedure for 139,264 Mbit/s".
[2] ETS 300 212: "Network Aspects (NA); Metropolitan Area Network (MAN) Media
access control layer and physical layer specification".
[3] IEEE Standard 802.6 (1990): "Distributed Queue Dual Bus (DQDB) Subnetwork
of a Metropolitan Area Network (MAN)".
3 Definitions
For the purposes of this ETS, the definitions as defined in IEEE Standard 802.6 [3] shall apply.
4 Symbols and abbreviations
For the purposes of this ETS, the symbols and abbreviations as defined in IEEE Standard 802.6 [3] shall
apply.
Additionally, for this PICS proforma, the following abbreviations are used in defining the support type of a
feature, parameter or capability:
m mandatory
o optional
c conditional
d default value defined
n/a not applicable
When used in the column labelled "Value", the following abbreviations are defined:
xx - yy from number xx to number yy
xx/yy either number xx or number yy applies, depending on the actual conditions
For each of the conditional items, an explanation of the parameter or capability under which the feature,
parameter or capability is mandatory, is given in the Clause or subclause in which the conditional items
appear.
The notation X_ in the column "Support" means that numbers may be entered in this place pointing to notes
which indicate deviation from the standard.

For ease of reference, the numbering of the following Clauses is identical to that contained in ETS 300 215
[1].
5 PICS for the "PLCP for E4 based systems"
An implementation is required to conform to the functional models defined in ETS 300 215 [1] with regard
to all of the externally observable effects.
