Abstract
An end office of the PSTN, which employs independent switching networks which share one or more office codes, is served by a single assigned node on the CCS network. The signaling processor which serves the assigned node, screens all incoming call messages (IAM)'s; directs messages which include an appropriate Channel Identification Code (CIC) to the switching network that serves that CIC; rejects messages that include an improper CIC; and requests that the calling office assign a different CIC to the incoming call.
