An end office (102) of the PSTN (101), which employs independent switching networks (103, 104) which share one or more office codes, is served by a single assigned node (105) on the CCS network. The signaling processor (106) which serves the assigned node (105), screens all incoming call messages (IAM)'s (191); 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.
Un seul noeud assigné (105) d'un réseau de signalisation à canaux communs dessert un central récepteur (102) d'un réseau téléphonique public (101) qui utilise des réseaux de commutation indépendants (103, 104) qui se partagent un ou plusieurs codes de centraux. Le processeur de signalisation (106) qui dessert le noeud assigné (105) examine tous les messages d'appel (191), oriente les messages qui comportent le code d'identification de canal (CIC) approprié vers le réseau de commutation qui fournit le code d'identification de canal (CIC), rejette les messages qui comportent un code d'identification de canal (CIC) incorrect; et demande que le central d'appel attribue un code d'identification de canal (CIC) différent à l'appel qui arrive.
