'' process and apparatus to transmit signal information in a telecommunications network between a pair of parts of the application, and.The node connection for attaching signal information of a network signaling common channel of a telecommunications system to a network based on Internet Protocol ''.A process of transmitting signalling information in a public land mobile network (PLMN) between a pair of parts of the application of the pair.A layer of adaptation is interposed between the SCCP of a SS7 network and a part of TCP / IP to allow data being transmitted to and from the SCCP signalling by an IP based network.The adaptation layer provides translation between the destination point code (DPCs) and / or global securities, used as addresses in the network of SS7 and IP address / port numbers for use in the IP network.The layer of adaptation also provides formatting of messages of SCCPs suitable for processing by the layers of TCP / IP, and also to format signal information flowing in the opposite direction.
