<p>PROBLEM TO BE SOLVED: To provide a telecommunication network and a method for routing originated call. SOLUTION: The routing of originated calls in telecommunication switching systems 121 and 122 composed of one or more fabrics 221 , 222 and 223 under the control of correspondent fabric controllers 261 , 262 and 263 is performed independently of fabrics by a routing processor 28. The routing processor selects routes for respective originated calls and carries the originated calls by actually designating channels to nearby switching systems. Further, the routing processor responds to an inquiry from the other switching system concerning a trunk group state and traffic load and has ability for the processor to determine the route while supporting the routing processor of the other switching system.</p> |
