What are stateful and momentary control sequences on a tone-controlled radio?
A. Cisco IPICS enables the following controls on a tone-controlled radio: •Stateful controls—Control functions can display on the PMC as single channel selector buttons or as stateful control sequences. Stateful control sequences are comprised of multiple states, where each state displays as a separate channel selector (tone control) button on the PMC. An example of a stateful control sequence is the power level of a radio. •Momentary controls—Momentary tones begin to play when the PMC user presses the associated button. After the user presses a momentary control button, the button appears to be pressed momentarily before it appears raised again.
