Maximum user signaling rate
Encyclopedia
In telecommunication
, maximum user signaling rate, synonymous to gross bitrate or data signaling rate
, is the maximum rate, in bits per second, at which binary
information
can be transferred in a given direction between users over the telecommunications system
facilities dedicated to a particular information transfer
transaction, under conditions of continuous transmission
and no overhead information
.
For a single channel
, the signaling rate is given by , where SCSR is the single-channel signaling rate in bits per second, T is the minimum time
interval in seconds for which each level must be maintained, and n is the number of significant conditions of modulation
of the channel.
In the case where an individual end-to-end telecommunications service
is provided by parallel channels, the parallel-channel signaling rate is given by , where PCSR is the total signaling rate for m channels, m is the number of parallel channels, Ti is the minimum interval between significant instants for the I-th channel
, and ni is the number of significant conditions of modulation
for the I-th channel.
In the case where an end-to-end telecommunications service
is provided by tandem
channels, the end-to-end signaling rate is the lowest signaling rate among the component channels.
Telecommunication
Telecommunication is the transmission of information over significant distances to communicate. In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages via coded...

Data signaling rate
In telecommunication, data signaling rate , also known as gross bit rate, is the aggregate rate at which data pass a point in the transmission path of a data transmission system.Notes:#The DSR is usually expressed in bits per second....

Information
Information in its most restricted technical sense is a message or collection of messages that consists of an ordered sequence of symbols, or it is the meaning that can be interpreted from such a message or collection of messages. Information can be recorded or transmitted. It can be recorded as...

Information transfer
In telecommunications, information transfer is the process of moving messages containing user information from a source to a sink.Note: The information transfer rate may or may not be equal to the transmission modulation rate.-See also:...

Transmission (telecommunications)
Transmission, in telecommunications, is the process of sending, propagating and receiving an analogue or digital information signal over a physical point-to-point or point-to-multipoint transmission medium, either wired, optical fiber or wireless...

Overhead information
Overhead information is digital information transferred across the functional interface between a user and a telecommunications system, or between functional units within a telecommunications system, for the purpose of directing or controlling the transfer of user information or the detection and...
