<p>PURPOSE:To secure a quick transmission of the signal featuring a high priority in case the transmission is required for the signal of a high priority, by transmitting the high-priority signal by being intruded in the form of group into the current of the low-priority signal. CONSTITUTION:The synchronous signal showing the start of the multiple signal, the signal showing the interruption and the signal showing a high degree of emergency are allotted to the group of channel 00, 10, 20 ..., channel 01, 11 .. and channel 02-09 respectively. Now in case the emergency signals allotted to channels 02-09 are required to transmit during transmission of channels 10-19 after transmission of channels 00-09, channels 00-09 are transmitted again after transmission of 10-19 to show the emergent abnormal state. Then the signals of 10-19 and 20-29 and so on are transmitted in sequence. In such way, the high-priority signal is intruded by group into the current of the low-priority signal for the quick transmission.</p> |
