When constructing/upgrading an optical transport communication system, high demands are placed on its topology, fault tolerance and redundancy. An audit is necessary to collect information required to conduct a full analysis, describe the current state and the required upgrade.
An audit makes it possible to obtain the most reliable data on the current state of the network topology, the equipment used, the relevance of its software and hardware, the need for its modernization or replacement, to identify problems that affect the network's throughput and stability.
