Network Management and Security A telecommunication Management Network, commonly known as TMN, is an infrastructure that provides interfaces for connection between several types of operating systems and telecommunications equipment, so as to manage the telecommunication service and network. This is from Glenn Warnock and Nathoo Amin (215). Also, it enables the functioning of the management information, which is exchanged through these interfaces. On the other hand, 5620 SAM is widely used for developing distributed systems, as it provides the infrastructure for interoperability of several object oriented management applications. With this application, the 5620 enables applications of operating systems to interoperate with the service access manager, allowing it to provide connections, isolate and manage network issues across an Alcatel network (225). With this, users can access management information transparently and independent of the hardware and software platform. This therefore enhances the portability of applications, which are developed across the multiple platforms of management. The principles and concepts of the TMN that can be matched with the features and functions of the 5620 platforms include the specification translation and the interaction translation. Redundancy is also an important feature. It is the automatic transfer of data network to stand by, and protects the network against hardware failure, software failure and connectivity problems. According to Kent Hudley (128), fault tolerance is also significant in the carrier networks so as to provide reliability and maintain the availability of the system, even under the conditions of failure. For this to occur, the 5620 SAM has to use the hardware and software for redundancy.
