SDH network equipment architecture controlled by multi operation systems

Abstract

With the progress of network management technology and the necessity of the multivendor environment, it is proposed to introduce TMN (telecommunications management network) architecture and OpS (operation systems) based on the TMN model. It is important that the NE (network element) which works under the current OpS is transferred to the new OpS based on the TMN. We describe the NE architecture which is controlled both under the current OpS and the new OpS based on the TMN architecture and show the SDH equipment-1.5 Mbit/s cross-connect- adopting this structure.
