PURPOSE:To reduce the processing capability required for the connection control processor to reduce the number of required connection control processors, by performing the connection processing between the nondelay starting trunk below and the incoming register trunk by the control of only the signal control processor in case that incoming of the call to the nondelay starting trunk is detected. CONSTITUTION:Signal control processors 11-1n are provided with a means to detect incoming of the call to nondelay starting trunks 21-2n, a means to select incoming register trunk 3 by detection of incoming of this call, and a means to control channel switch 5 so that nondelay starting trunks 21-2n may be connected to incoming register trunk 3. In case that incoming of the call to nondelay starting trunks 21-2n is detected, the connection processing between nondelay starting trunks 21- 2n and incoming register trunk 3 is performed according to the control of only signal control processors 11-1n. |
