<p>PROBLEM TO BE SOLVED: To enable relay among switch boards without reviewing the number systems of them even when adopting different number systems. SOLUTION: An SVC controller 13 finds out special numbers in incoming numbers transmitted from line interface parts 151-15m and 161-16m, identifies the line interface parts 151-15m and 161-16m to be relayed and transmits the incoming numbers. The line interface parts 151-15m and 161-16m receive the incoming numbers from the SVC controller 13, edit them according to the number edit conditions previously informed and then transmit them to lines 31-3n and 51-5m connected to themselves.</p> |
