Abstract

PURPOSE:To set an extension number of each extension telephone set simply without duplication by allowing a master system to send a command of generating an alarm tone to an extension telephone set sending a command representing the setting of an extension number and an extension telephone set sending a command representing a duplicated extension number. CONSTITUTION:An extension/external line control CPU 22 of an extension telephone set 20 sends a command and its extension number representing the setting of an extension number and an extension/external line control CPU 12 of an extension telephone set 10 sends a command representing the duplicate setting of an extension number by using the command from the CPU 22. Then extension/external line control CPU 2 of a master system 1 sends a command to ring an alarm tone to extension telephone sets 10, 20. Thus, an alarm tone is generated from both the extension telephone set 10, 20 whose extension numbers are set in duplicate. Thus, the extension number of each extension telephone set is set simply without duplication.
