Maximum user signaling rate

From Wikipedia, the free encyclopedia

In telecommunication, maximum user 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, T_i is the minimum interval between significant instants for the I-th channel, and n_i 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.
