Sec. 90.647 Station identification.
(a) Conventional systems of communication shall be identified in accordance
with existing regulations governing such matters.
(b) Trunked systems of communication, except as noted in paragraph (c) of
this section, shall be identified through the use of an automatic device
which transmits the call sign of the base station facility at 30 minute
intervals. Such station identification shall be made on the lowest frequency
in the base station trunk group assigned the licensee. Should this frequency
be in use at the time station identification is required, such
identification may be made at the termination of the communication in
progress on this frequency. Identification may be made by voice or
International Morse Code. When the call sign is transmitted in International
Morse Code, it must be at a rate of between 15 to 20 words per minute and by
means of tone modulation of the transmitter, the tone frequency being
between 800 and 1000 hertz.
(c) Stations operating in either the 806–824/851–869 MHz or 896–901/935–940
MHz bands that are licensed on an exclusive basis, and normally employ
digital signals for the transmission of data, text, control codes, or
digitized voice may also be identified by digital transmission of the call
sign. A licensee that identifies its station in this manner must provide the
Commission, upon its request, information sufficient to decode the digital
transmission and ascertain the call sign transmitted.
(d) Notwithstanding the requirements set forth in this paragraph, systems
operated by geographic area CMRS licensees are subject only to the station
identification requirements of Sec. 90.425(e).
