PURPOSE:To minimize a connection route up to a terminal to be called and to attain storage of calls to any station with the terminal number kept fixed, by discriminating and relaying the call connection information on the terminal to be called to all exchange stations in a network. CONSTITUTION:When a terminal (a) dials the subscriber number of a terminal (d), a station A discriminates no mutual connection within its own station and then sends the call connection information on the terminal (d) to station B and C. Both stations B and C transmit the call connection information on the terminal (d) to stations excepting the station A (to stations C and D with the station B and to stations B and D with the station C) after discriminating that the terminal (d) is not included in their own stations. In this case, the station B, for example, receives the information from the station A and receives the information on the small call connection also from the station C. However the information received from the station C, i.e., the new information received previously is disused. Then the station D receives the call connection information on the terminal (d) from both stations B and C and then calls and connects the terminal (d) according to the earlier one of information given from both stations B and C. Then the slower information is disused. |
