Signaling network operations system (SIGNOS) in Korea

The authors describe an operations system designed to establish the network management and provisioning functions for a CCS (common channel signaling) network being deployed in Korea. The SIGNOS, which is a sort of centralized system to accommodate a number of SMX-1s (signaling message exchanges), consistently monitors and maintains the CCS network from a networkwide point of view to assure efficient utilization of the network. The authors introduce the system architecture and functions of SIGNOS and present an example of the interface between the operations system and network elements. In order to resolve the interface between SMX-1 and SIGNOS, the authors apply part of SMX-1 itself to the front end of SIGNOS, anticipating that CCITT protocol no.7 will be suitable for signaling network management in the future
