Abstract

PURPOSE:To prevent interference due to the collision of calls and the lowering of line efficiency from being generated, by performing all of the delivery of telegrams by a prescribed procedure under the control of a specific station when the specific station sends the telegram to plural stations. CONSTITUTION:Firstly, a seaside station (specific station) informs a station having the telegram to be transmitted by the unidirectional error character correcting mode and simultaneous call system of periodical print telegraph communication and a call frequency to plural ship stations. Next, corresponding ship stations are called station by station by an informed call frequency by an automatic re-sending request mode and selective call system, and the telegram is sent. when no response is obtained from the ship station, a call by a different frequency is performed sequentially. It is advisable to register the frequency of the ship station in advance to heighten call efficiency. By constituting a system in such way, it is possible to prevent simultaneous call to the seaside station by the ship stations receiving information of the presence of transmission telegrams in a large number of ships to be called from being performed, and to prevent the interference due to the collision of the calls and the error of a reception code from being generated.
