PURPOSE:To make all cordless telephone sets available even in the case of residence in any speech zone and not to limit a speech zone number by imparting the same system ID to plural radio connection devices and plural cordless telephone sets connecting to plutal master sets and preventing each speech zone from being overlapped with each other. CONSTITUTION:The same system ID is imparted to radio connectors 511-51k, 521-52k and cordless telephone sets 61, 62,... in the integrated cordless telephone system 2. For example, when the cordless telephone set 61 is resident in a speech zone Z1 of an individual cordless telephone system 31 and an event of a call takes plate, a sent dial signal is acquired by an extension 11 of a private branch of exchange 1 via any of the radio connectors 511-51k and a master set 41. In this case, since no overlap is in existence among speech zones Z1-Zm of plural individual cordless telephone sets 31-3m, the other individual cordless telephone sets 32-3m do not receive a dial signal from the cordless telephone set 61. |
