The present invention relates to managing an inter-communications system for a ship by combining two inter-communications systems. The system management of the present invention integrates an automatic telephone system (a telephone exchange system within a ship, which has basic functions such as an extension, a local call, and a paging to enable telephone calls within the ship and making a call from the sea to the ground through a satellite) and a public address system (a system which enables broadcast within a ship to broadcast programs or information such as danger alarms through loudspeakers installed all around the ship), both of which are individually constructed in an existing system management. [Reference numerals] (400) Telephone local/ extension |
