PURPOSE:To call lots of receivers in a shorter time by setting a transmission code comprising of the number as a reference of a serial number and several data when a consecutive call number is in existence. CONSTITUTION:A call number transmission means 1 sends a call number corresponding to a receiver to be called to a transmission data buildup means 2, a mode switching means 3 and a storage means 4. The call number is stored in the storage means 4 and the mode changeover means 3 discriminates whether the sent call number is a number adjacent to the call number stored in the storage means 4 and uses either a start or an end call number of a serial number as a reference call number when the number is adjacent and calculates several data to send it to the transmission data buildup means 2. The transmission data buildup means 2 combines the sent reference call number and several data to build up the transmission signal and sends the result to a transmission section. Through the constitution above, a cyclic transmission code being a set of individual call codes is compressed to call lots of receivers in a shorter time. |
