Abstract

PURPOSE:To improve operation with main-wire transfer attained through simple operation by allowing a transferred extension to dial a fixed number, by releasing the switch terminal of a 1st system connected to the switch terminal of a 2nd system and by completing the transfer connection of a main-wire trunk. CONSTITUTION:Main-wire trunk COT is provided with trunk switch terminals A and B of the 2nd system and only while transfer extension EXTA connected carries out the transfer operation to switch terminal A of the 1st system, the selective route of switch terminal B of the 2nd system is formed. In case that transferred extension EXTB having been informed of the main-wire transfer from transfer extension EXTA dials a prescribed specific number, terminal A connected to switch terminal B of the 2nd system is released to complete the transfer connection to trunk COT. Consequently, the operation can be improved by attaining the main-wire transfer through simple operation.
