11  NBDP TRANSMITTING, RECEIVING 

11-3 

In ARQ operation, one station (information sending station) sends data to another block by 
block, then listens for the acknowledge signal between blocks from the information 
receiving station which requests either the next block or retransmission of the last block if 
there is error. The request may be repeated up to 32 times, until the complete block is 
received free of error.

3.  Choose a station. (Station must be registered for use in the ARQ mode). Press the 

[Enter] key. The message "Calling Station" appears. If the message "Station calling 
suspended. Check radio and interconnections. Press any key to escape." appears, 
check both the power of the radiotelephone and the connections between the 
radiotelephone and the NBDP Terminal Unit.

communication status display (see below). 
Note: If signal conditions are poor, connection may take a while. If the line could not 

be connected in one minute, calling stops and "Calling failed" appears. Try step 
3 again, one minute later. Should signal conditions worsen during message 
transmission, "Error" appears in reverse video and 30 seconds later the line is 
disconnected.
