Foreword
This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical
Committee Electromagnetic compatibility and Radio spectrum Matters (ERM).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC [7] laying down a procedure for the provision of information in the field of technical
standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC [1] of the European Parliament and
of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive").

The left hand edge of the figure 1 shows the different subclauses of Article 3 of the R&TTE Directive [1].
For article 3.3 various horizontal boxes are shown. Dotted lines indicate that at the time of publication of the present
document essential requirements in these areas have to be adopted by the Commission. If such essential requirements
are adopted, and as far and as long as they are applicable, they will justify individual standards whose scope is likely to
be specified by function or interface type.
The vertical boxes show the standards under article 3.2 for the use of the radio spectrum by radio equipment. The
scopes of these standards are specified either by frequency (normally in the case where frequency bands are
harmonized) or by radio equipment type.
For article 3.1b the diagram shows the new single multi-part product EMC standard for radio, and the existing
collection of generic and product standards currently used under the EMC Directive [2]. The parts of this new standard
will become available in the second half of 2000, and the existing separate product EMC standards will be used until it
is available.
For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive [3] and new
standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be
required.
The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal
equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both. A radio
spectrum standard will apply if it is radio equipment. An article 3.3 standard will apply as well only if the relevant
essential requirement under the R&TTE Directive [1] is adopted by the Commission and if the equipment in question is
covered by the scope of the corresponding standard. Thus, depending on the nature of the equipment, the essential
requirements under the R&TTE Directive [1] may be covered in a set of standards.
The modularity principle has been taken because:
- it minimizes the number of standards needed. Because equipment may, in fact, have multiple interfaces and
functions it is not practicable to produce a single standard for each possible combination of functions that may
occur inanequipment;
- it provides scope for standards to be added:
- under article 3.2 when new frequency bands are agreed; or
- under article 3.3 should the Commission take the necessary decisions;
without requiring alteration of standards that are already published;
- it clarifies, simplifies and promotes the usage of Harmonized Standards as the relevant means of conformity
assessment.

1 Scope
The present document applies to CT1 and CT1+ cordless telephone terminal equipment.
These cordless telephone equipment types are capable of operating in all or any part of the frequency bands given in
table 1:
Table 1: Cordless Telephone service frequency bands
Cordless Telephone service frequency bands
Portable Part CT1 914,0125 MHz to 914,9875 MHz
Fixed Part CT1 959,0125 MHz to 959,9875 MHz
Portable Part CT1+ 885,0125 MHz to 886,9875 MHz
Fixed Part CT1+ 930,0125 MHz to 931,9875 MHz
It should be noted that the above frequency bands are not harmonized throughout the community.
The existence of this Harmonized Standard does not imply the availability of the above frequency spectrum for the
particular types of equipment covered by the present document.
The present document is intended to cover the provisions of Directive 1999/5/EC [1] (R&TTE Directive) Article 3.2,
which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as to avoid harmful interference."
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of Article 3 of the R&TTE Directive [1] will apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the web site http://www.newapproach.org.

4 Principles of operation and general requirements
4.1 Procedure to set up the RF connection between fixed and
portable part
Both fixed and portable part comprises a transmitter and a receiver which will perform full duplex operation. When the
need for a radio frequency channel arises in any of the parts of a cordless telephone, this part will act in general as
follows:
a) the initiating part searches for an idle duplex channel. A channel is considered to be idle if the initiating part of
the cordless telephone senses that the radio frequency field strength on that specific channel is below a specified
limit;
b) on the idle (duplex) channel, found under a), the initiating part starts transmitting signals to the desired part of
the same cordless telephone. These signals contain an identification code which offers at least 999999 different
combinations;
c) the receiver of each part of a cordless telephone is constantly scanning, searching for a signal which contains its
matching identification code. Upon detection of this code, the receiver stops scanning and initiates its transmitter to
return its identification code to the initiating part on this duplex channel;
d) as the receiver of the initiating part detects its matching identification code on the return frequency of the selected
duplex channel, the duplex channel becomes available.

The left hand edge of the figure 1 shows the different subclauses of Article 3 of the R&TTE Directive [1].
For article 3.3 various horizontal boxes are shown. Dotted lines indicate that at the time of publication of the present
document essential requirements in these areas have to be adopted by the Commission. If such essential requirements
are adopted, and as far and as long as they are applicable, they will justify individual standards whose scope is likely to
be specified by function or interface type.
The vertical boxes show the standards under article 3.2 for the use of the radio spectrum by radio equipment. The
scopes of these standards are specified either by frequency (normally in the case where frequency bands are
harmonized) or by radio equipment type.
For article 3.1b the diagram shows the new single multi-part product EMC standard for radio, and the existing
collection of generic and product standards currently used under the EMC Directive [2]. The parts of this new standard
will become available in the second half of 2000, and the existing separate product EMC standards will be used until it
is available.
For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive [3] and new
standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be
required.
The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal
equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both. A radio
spectrum standard will apply if it is radio equipment. An article 3.3 standard will apply as well only if the relevant
essential requirement under the R&TTE Directive [1] is adopted by the Commission and if the equipment in question is
covered by the scope of the corresponding standard. Thus, depending on the nature of the equipment, the essential
requirements under the R&TTE Directive [1] may be covered in a set of standards.
The modularity principle has been taken because:
- it minimizes the number of standards needed. Because equipment may, in fact, have multiple interfaces and
functions it is not practicable to produce a single standard for each possible combination of functions that may
occur inanequipment;
- it provides scope for standards to be added:
- under article 3.2 when new frequency bands are agreed; or
- under article 3.3 should the Commission take the necessary decisions;
without requiring alteration of standards that are already published;
- it clarifies, simplifies and promotes the usage of Harmonized Standards as the relevant means of conformity
assessment.

1 Scope
The present document applies to CT1 and CT1+ cordless telephone terminal equipment.
These cordless telephone equipment types are capable of operating in all or any part of the frequency bands given in
table 1:
Table 1: Cordless Telephone service frequency bands
Cordless Telephone service frequency bands
Portable Part CT1 914,0125 MHz to 914,9875 MHz
Fixed Part CT1 959,0125 MHz to 959,9875 MHz
Portable Part CT1+ 885,0125 MHz to 886,9875 MHz
Fixed Part CT1+ 930,0125 MHz to 931,9875 MHz
It should be noted that the above frequency bands are not harmonized throughout the community.
The existence of this Harmonized Standard does not imply the availability of the above frequency spectrum for the
particular types of equipment covered by the present document.
The present document is intended to cover the provisions of Directive 1999/5/EC [1] (R&TTE Directive) Article 3.2,
which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as to avoid harmful interference."
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of Article 3 of the R&TTE Directive [1] will apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the web site http://www.newapproach.org.

4 Principles of operation and general requirements
4.1 Procedure to set up the RF connection between fixed and
portable part
Both fixed and portable part comprises a transmitter and a receiver which will perform full duplex operation. When the
need for a radio frequency channel arises in any of the parts of a cordless telephone, this part will act in general as
follows:
a) the initiating part searches for an idle duplex channel. A channel is considered to be idle if the initiating part of
the cordless telephone senses that the radio frequency field strength on that specific channel is below a specified
limit;
b) on the idle (duplex) channel, found under a), the initiating part starts transmitting signals to the desired part of
the same cordless telephone. These signals contain an identification code which offers at least 999999 different
combinations;
c) the receiver of each part of a cordless telephone is constantly scanning, searching for a signal which contains its
matching identification code. Upon detection of this code, the receiver stops scanning and initiates its transmitter to
return its identification code to the initiating part on this duplex channel;
d) as the receiver of the initiating part detects its matching identification code on the return frequency of the selected
duplex channel, the duplex channel becomes available.
