§ 15.214 Cordless telephones.
(a) For equipment authorization, a single application form, FCC Form
731, may be filed for a cordless telephone system, provided the
application clearly identifies and provides data for all parts of the
system to show compliance with the applicable technical requirements.
When a single application form is submitted, both the base station and
the portable handset must carry the same FCC identifier. The
application shall include a fee for certification of each type of
transmitter and for certification, if appropriate, for each type of
receiver included in the system.
(b) A cordless telephone that is intended to be connected to the public
switched telephone network shall also comply with the applicable
regulations in part 68 of this chapter. A separate procedure for
approval under part 68 is required for such terminal equipment.
(c) The label required under subpart A of this part shall also contain
the following statement: "Privacy of communications may not be ensured
when using this phone."
(d) Cordless telephones shall incorporate circuitry which makes use of
a digital security code to provide protection against unintentional
access to the public switched telephone network by the base unit and
unintentional ringing by the handset. These functions shall operate
such that each access of the telephone network or ringing of the
handset is preceded by the transmission of a code word. Access to the
telephone network shall occur only if the code transmitted by the
handset matches code set in the base unit. Similarly, ringing of the
handset shall occur only if the code transmitted by the base unit
matches the code set in the handset. The security code required by this
section may also be employed to perform other communications functions,
such as providing telephone billing information. This security code
system is to operate in accordance with the following provisions.
(1) There must be provision for at least 256 possible discrete digital
codes. Factory-set codes must be continuously varied over at least 256
possible codes as each telephone is manufactured. The codes may be
varied either randomly, sequentially, or using another systematic
(2) Manufacturers must use one of the following approaches for
facilitating variation in the geographic distribution of individual
(i) Provide a means for the user to readily select from among at least
256 possible discrete digital codes. The cordless telephone shall be
either in a non-operable mode after manufacture until the user selects
a security code or the manufacturer must continuously vary the initial
security code as each telephone is produced.
(ii) Provide a fixed code that is continuously varied among at least
256 discrete digital codes as each telephone is manufactured.
(iii) Provide a means for the cordless telephone to automatically
select a different code from among at least 256 possible discrete
digital codes each time it is activated.
(iv) It is permissible to provide combinations of fixed, automatic, and
user-selectable coding provided the above criteria are met.
(3) A statement of the means and procedures used to achieve the
required protection shall be provided in any application for equipment
authorization of a cordless telephone.
