System composition


Division	Content	Notes
Optical line Automatic monitoring system (FiMS-PTP(PTM))	-System which monitors changes in optical loss after automatically and manually measuring backscattering waveforms of working optical lines with an optical pulse tester (OTDR). -Can conduct automatic monitoring, warning, and analysis of causes, and determine the distance and location of trouble following changes in the amount of optical electricity due to the physical transformation of optical lines and environmental effects. - Can manage the information of facilities and circuits related to optical lines.
Features	- For monitoring wavelength, use 1625 nm (ITU). (1310 nm or 1550 nm may also be selected) -Structure enables the addition of more optical switch ports when there is an expansion in the number of target optical lines. -Can monitor non-working or working lines.

Function	Screen composition	Function explanation
Obstacle management		- Current situations of areas in which hazards have occurred to cables, transmission equipment and monitoring systems, and the mobilization to recover facilities are shown in real-time. - After facilities have been recovered, it is possible to monitor recovery reports. - There is a function to provide warning via radio waves about the occurrence of hazards, which can be done through SMS, visible, audible and other warnings.
Facility management		- Manage database of optical cable facilities. - Cables are managed by straight figure. - Facilities to be managed include cables and line facilities.
Circuit management		- Manage circuits composed by cables linked with transmission systems among subscribers or among bureaus. - With automatic information, the locations of a transmission system and routes of cables linked with it are shown on the map. - Linked with other NMS, the information about circuits can be mutually exchanged.
Application management		- For daily application management jobs, the regular checking of cables and line facilities is supported. - Based on the established data, the change progress of cables can be observed, and problems can be predicted on this basis. - By predicting problems, the reliability of communication lines is improved through the application of preventive measures, such as changing cables before issues occur, or re-accessing access points.


Function	Screen composition	Function explanation
Statistics management		- Gather and store collected data by time unit (hour, day, week, weekday, month) to derive statistical data. - An operator can define the standards and time for the handling of data. - By managing statistics, the packet loss ratio, obstacle ratio, operation ratio, causes of troubles and feature management for each type of cable can be understood.
