In order to manage the operation of the COT 12 and the RT (that is, FLC) 13, a plurality of COTs are connected to a LAN, and one of them is designated as a main medium connected with the operation terminal 13, and a main medium It is designed to manage a plurality of optical subscriber transmission devices (FLC) through the "RS-422" interface between the designated COT and the operating terminal 13.

As shown in Figure 1, the conventional optical subscriber transmission device (FLC) operating terminal 11 was available only in the telephone station in which the device is installed for the operation management of the connected COT 12 and RT (13).

However, in order to manage end-to-end between subscribers and provide the desired service, management is required at the whole communication network level including adjacent transmission devices as well as FLC. Depending on the situation, a specific network management center can view the entire communication network. Operational commands necessary for the FLC or the transmitter should be available.

Therefore, in order to satisfy these demands, it is necessary to centrally manage and remotely operate FLCs that are distributed and operated, and to monitor and manage the alarm and configuration states of all FLCs connected in one system.

The present invention, which is devised to meet the demand as described above, to monitor and manage the alarm and configuration status of all FLCs connected in one system by centrally managing and remotely operating FLCs distributed and operated respectively. It is an object of the present invention to provide a centralized management method and a computer readable recording medium recording a program for realizing the method.

That is, the present invention provides each optical subscriber transmission device using another RS-422 multiport remaining while maintaining the configuration of the management of the optical subscriber transmission device (FLC), which is concentrated on one main medium telephone station equipment (COT). By setting up multiple access devices connected to the FLC and connected to the centralized management system and the LAN, the state of the alarm occurrence of the connected FLCs by concentrating the distributed FLCs And a centralized management method capable of remotely operating and managing configuration and a computer readable recording medium having recorded thereon a program for realizing the method.

The present invention for achieving the above object, in the centralized management method of the optical subscriber transmission device (FLC), the alarm message of the centralized management system automatically reported from the optical subscriber transmission device through the multiple communication processor of the multiple access device; A first step of collecting, analyzing, and storing a collector, and searching and displaying the optical subscriber transmission device in which the alarm and the state change designated by the automatic report message have occurred; And selecting one of a plurality of optical subscriber transmitters (FLCs) from a remote operating terminal and sending an operation command to the selected optical subscriber transmitters (FLCs) through a message processor of a centralized management system and a multiple communication processor of a multiple access apparatus. And a second step of receiving and displaying the result.

In addition, the present invention, in the centralized management system for the optical subscriber transmission device having a processor, the alarm collector of the centralized management system collects and analyzes the messages automatically reported from the optical subscriber transmission device through the multiple communication processor of the multiple access device. And storing and retrieving and displaying to the operator an optical subscriber transmission apparatus in which an alarm and a state change designated by the automatic report message are generated. And selecting one of a plurality of optical subscriber transmitters (FLCs) from a remote operating terminal and sending an operation command to the selected optical subscriber transmitters (FLCs) through a message processor of a centralized management system and a multiple communication processor of a multiple access apparatus. A computer readable recording medium having recorded thereon a program for realizing the function of receiving and displaying the result is provided.
