  First, an extension number is dialed (on-net connection) or a telephone number of 0+ “0A to J” is dialed from the calling member's net service subscriber terminal 2A to the called subscriber terminal 2B having the same group number ( Off-net connection) (step S701). Next, when the originating exchange (GC) 18 recognizes that the call originates from a members net subscriber, it makes an inquiry to the network service control station (NSP) 19 (step S702).

  Next, the NSP 19 (1) in the case of on-net connection, converts the extension number into a telephone number of “0A to J”, checks the connection condition and the destination subscriber condition, and sends it to the originating exchange (GC) 18. A telephone line connection instruction is issued. (2) In the case of an off-net connection, the connection condition is checked, and a connection instruction is issued using the telephone numbers “0A to J” (step S703). If the connection cannot be permitted under the connection condition (1) or (2) or the destination subscriber condition, the NSP 19 instructs the originating exchange to make a non-permitted talk connection, and the originating exchange 18 The guidance notification function (ARE) sends a connection non-permissible token to the originating member's net service subscriber terminal.

  Next, the originating exchange (GC) 18 performs routing using the telephone numbers “0A to J” based on an instruction from the NSP 19 (step S704). Next, the destination exchange (GC) 18 identifies whether it is an on-net connection or an off-net connection, and performs an incoming connection to the member's net service subscriber terminal 2B (incoming terminal) on the incoming side ( Step S705). As a result, the connection of the telephone line using the member's net service is realized, and the telephone call becomes possible. This is the end of the description of the telephone line connection procedure in the members net service.
