A form of telecommunication for the reproduction
at a distance of graphic documents in the form of other graphic documents geometrically
similar to the original. |

First Coaxial/HFC Termination Point |
The first interface device at the end of a
line connecting the customer to the network provider's telecommunications network
enabling the supply of telecommunications service and/or for the transmission of
other services to the customer. |

Fixed Line Traffic |
Volume of traffic carried over the Public
Switched Telephone Network. Calls refer to the actual number of completed calls.
Minutes refer to the number of minutes of use. |
ITU (Fixed Line Traffic) |

Fixed Link And Cable |
A network facility to enable communication
between two stations, channels or adjacent nodes of a network and is part of a communications
system. |

Fixed Service |
A radiocommuncations service between specified
fixed points. |
SR |
| 202. |
Fixed Station |
A station which is located in a specified
location and is intended to be used in that specified location. |
SR |
| 203. |
Fixed-Satellite Service |
A radiocommuncations service between earth
stations at a given position, and when one or more satellites are used, the given
position may be a specified fixed point or any fixed point within a specified area
and includes a satellite to satellite links which may also be operated in the inter-satellite
service and feeder links for other space services. |
SR |

Free Phone |
A service which permits the cost of the call
to be charged to the called party, rather than the calling party. |

| 207. |
Frequency band |
A continuous set of frequencies lying between
two specified limiting frequencies.
| Note |
-
|
A frequency band is characterized by two values,
which define its position in the frequency spectrum, for example, its lower and upper
limiting frequencies. |
|
ITU |
| 208. |
Frequency Band |
A continuous frequency range of spectrum. |
CMA |
| 209. |
Frequency bandwidth |
The quantitative difference between the limiting
frequencies of a frequency band.
| Note 1 |
-
|
The term "bandwidth" is usually
associated with a qualification, for example:
- baseband bandwidth;
- necessary bandwidth;
- bandwidth of an amplifier or other device. |
| Note 2 |
-
|
A bandwidth is defined by a single value and
does not depend upon the position of the band in the frequency spectrum. |
|
ITU |
| 210. |
Frequency channel |
Part of the frequency spectrum intended to
be used for a transmission of signals and which may be defined by two specified limits,
or by its centre frequency and the associated bandwidth, or by any equivalent indication.
| Note 1 |
-
|
A frequency channel may be time-shared in
order to allow communication in both directions by simplex operation. |
| Note 2 |
-
|
The use of the term "channel" to
mean "telecommunication circuit" is deprecated. |
| Note 3 |
-
|
The term "radio-frequency channel"
used in radiocommunication is defined in CCIR Recommendation 573. |
|
ITU |
| 211. |
Frequency departure |
An unintentional frequency separation from
a stated frequency. |
ITU |
| 212. |
Frequency division |
A technique whereby a separate distinct frequency
band is used for each transmission channel, for example in multiplexing, switching
or multiple access operations. |
ITU |
| 213. |
Frequency drift |
An undesired progressive and slow change in
frequency with time. |
ITU |
| 214. |
Frequency offset |
A small intentional frequency change for purposes
other than that of modulation.
| Note |
-
|
A frequency offset may be affected, for example,
as a means of avoiding or minimizing interference. |
|
ITU |
| 215. |
Frequency shift |
An intentional frequency change produced by
modulation, or an unintentional change due to a natural phenomenon. |
