Description

Integrated operation management system of synchronous optical transmission device

The present invention relates to an integrated operation management system of a synchronous optical transmission apparatus (SMOT), and more particularly, to operate various types of synchronous optical transmission apparatuses having different transmission bandwidths using one integrated operation terminal. And it relates to an integrated operation management system of the synchronous optical transmission device to be managed.

In general, as the information society wants to transition to an information society, a large capacity optical transmission apparatus capable of transmitting a large amount of data at high speed is required. In addition, the transmission network, which is becoming more complicated due to the increase in the traffic volume, is being converted into a synchronous transmission network for the purpose of simplifying network construction and economical network construction.

In order to cope with such changes in the network environment, 155Mbps, 622Mbps, and 2.5Gbps synchronous optical transmission devices (hereinafter referred to as SMOT-1 and SMOT-4 SMOT-16, respectively) have been developed and operated. The operating terminal that operates and monitors (SMOT-1 / -4 / -16) monitors each transmission device and network in real time to generate alarms and status messages, collects various information, and transfers lines. Other features such as security and data accumulation.

In this regard, FIG. 1 is a block diagram schematically showing a conventional synchronous optical transmission device and an operation terminal. As shown in the drawing, the conventional synchronous optical transmission device (SMOT-1 / -4 / -16: 11, Separate operating terminals 14, 15, and 16 are installed for each of the models 12 and 13, and are in charge of the operation and maintenance of the corresponding optical transmission device. Each transmission device (SMOT-1 / -4 / -16) A switch type RS-422 signal is used as a communication signal between 11, 12, and 13 and the corresponding operation terminals 14, 15, and 16.

As shown in the drawing, the conventional synchronous optical transmission apparatus has to have separate operation terminals having their operation and maintenance functions for each optical transmission apparatus, so that the number of operating terminals when the optical transmission apparatus is expanded is also proportional to this. It must be enlarged, and this causes a problem that the overall system construction cost is excessively consumed and a problem of excessively occupying the entire area of the transmission room.

In addition, conventionally, since a plurality of operating terminals are distributed and operated for monitoring and operation management of many optical transmission devices, real-time operation management of the entire optical transmission device is difficult and centralized operation management is impossible.

For example, the operation terminal 15 of the class 622 Mbps synchronous optical transmission device (SMOT-4: 12) is operated by a man-machine matching (hereinafter referred to as MMI) method and a 155 Mbps synchronous type. The operation terminals 14 and 16 of the optical transmission device (SMOT-1: 11) and the synchronous optical transmission device (SMOT-16: 13) of the 2.5 Gbps class are operated by a graphical user interface. Therefore, the operation of each operation terminal (14, 15, 16) is different depending on the type of the synchronous optical transmission device (11, 12, 13) has a disadvantage that it is difficult to manage in a unified operation environment.

In addition, since the operation terminal 15 of the SMOT-4 12 is operated by the MMI method, it is difficult to easily determine a failure state of the transmission apparatus, and the operation terminal 16 of the SMOT-16 13 is currently logged in. There is a limitation that real-time monitoring is possible only for the transmitting device.

In addition, since the operation terminals 15 and 16 of the optical transmission apparatuses SMOT-4 and SMOT-16 except for the operation terminal 14 of the SMOT-1 11 do not have a statistical function, various statistics required by the operators are required. There is a difficulty in providing the data smoothly.

Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, and the centralized operation management and real-time operation of the synchronous optical transmission apparatus by replacing the operation terminal of each type of each synchronous optical transmission apparatus with one integrated operation management apparatus. The purpose is to provide an integrated operation management system of a synchronous optical transmission device that enables operation monitoring.
