Abstract

PURPOSE:To facilitate installation of more extensions lines, by multiple-storing the incoming system central office trunk in both exchanges in the private branch exchange where extensions are divided and stored in two sets of common control system exchanges. CONSTITUTION:Extensions ETXA and ETXB are divided and stored in two sets of exchanges PBXA and PBXB. Incoming system central office trunk COT is multiple-stored in respective switch frames LLFA and LLFB of both exchanges PBXA and PBXB. Marker MKRA is started to execute connection if trunk COT and extension EXTA are connected by the first number of the extension number, and marker MKRB is started to execute connection if extension EXTB is connected. Consequently, exchange PBXB can be extended while operating current exchange PBXA, and increased extensions can be stored in exchange PBXB, and further, incoming from the trunk wire can be connected to any stored extension.
