Abstract

PURPOSE:To prevent data from overflowing to drop out, by providing a means which generates an alarm when a transmission buffer of a terminal runs short and releases the alarm. CONSTITUTION:Input data is inputted to an input controlling circuit 21, and a transmission telegram is generated in a transmission telegram generating circuit 22 and is written into one block of a transmission buffer memory 24 through a writing circuit 23. Contents of an editing completion pointer and a transmission completion pointer for every one block are sent to a buffer near end detecting circuit 28 through an AND circuit 27 for every one block and are discriminated. In case of near end, an alarm driving signal is sent to an alarm circuit 30 to light an input alarm, and the intermittent tone of a speaker is generated. Next, a near end detection inhibiting signal is sent to the AND circuit 27 to inhibit the input to the buffer near end detecting circuit 28, and the transmission buffer memory takes in new data.
