Selective Calling
MDC-systems have an option for selective calling. By pressing a series of keys on the encoder-decoder, the base station operator can send a data packet that activates a lighted indicator or makes the radio beep. On some radio models with alphanumeric displays, the display may flash CALL until a reset button is pressed. On radio models with ten key pads, mobile radios may be programmed to selectively call one another in this manner. In order to call a radio, the calling party must know the four-digit MDC identity of the radio to be called.
In a CAD environment, a tow truck could be automatically called at the moment the driver was dispatched to respond to a call for service. The CAD system could manage the four-digit IDs so that the user did not need to know them.

Famous quotes containing the words selective and/or calling:
“The selective memory isn’t selective enough.”
—Blake Morrison (b. 1950)
“Instead of calling on some scholar, I paid many a visit to particular trees, of kinds which are rare in this neighborhood, standing far away in the middle of some pasture, or in the depths of a wood or swamp, or on a hilltop.... These were the shrines I visited both summer and winter.”
—Henry David Thoreau (1817–1862)
