<p><P>PROBLEM TO BE SOLVED: To provide an obstacle transmission method in the interconnection communication network, among different communication enterprisers for transmitting the line closure information of an IP network to a public network communication enterpriser through a main signal transmission line. <P>SOLUTION: A call connection controller 110 and a line connector 120, provided in a management network 100, are connected with a public network exchange 210 provided in a public network 200 through a common channel signal line 310 and a main signal transmission line 312, respectively, in an interconnection communication network. The obstacle transmission method comprises a step for recognizing a line on which a line trouble has occurred in the management network 100 using the line connector 120, a step for delivering line obstacle alarm, corresponding to the line on which a line trouble has occurred to the public network exchange 210 through the main signal transmission line 312 using the line connector 120; a step of suppressing calling to the line on which a line obstacle has occurred by receiving the line obstacle alarm from the public network exchange 210, and a step for closing the line on which a line obstacle has occurred by detecting the line on which a line trouble has occurred, when communicating with the line connector 120 using the call connection controller 110. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
