The present invention relates to a method and a server for automatically verifying a parameter of an optical transmission station transmitting equipment notified by a message or an electronic mail.

In recent years, communication using mobile phones and the Internet has been rapidly developed toward the transmission of still images and videos beyond the level of simply exchanging voice or text data. Meanwhile, the commercialization of video conferencing and high-definition TV is rapidly progressing. As a result, the demand for high-speed information and communication technology is increasing exponentially. As a result, the demand for communication is rapidly expanding in all areas of society, and the increase of the transmission speed of the communication network to meet this problem is emerging as a problem to be solved urgently.

Conventionally, conventional communication networks are classified into a wired network using a twisted-pair cable, a coaxial cable, an optical cable, and a wireless communication network using microwave as a transmission medium. However, wired networks using twin-twisted or coaxial cables have shortcomings of shorter effective transmission distances and narrower transmission bandwidths.Wireless networks using microwaves have wider bandwidths than coaxial wires. It is sensitive to changes in security and weak in information security.

On the other hand, the point where the optical fiber and coaxial cable of HFC (Hybrid Fiber Coaxial Cable) are in contact with each other should have a device that converts the optical cable and the coaxial cable into an interconnectable signal. do. HFC (Hybrid Fiber Coaxial Cable) is a hybrid of fiber and coaxial cable. It has excellent bi-directional characteristics. However, coaxial cable is used from the optical end to the subscriber.

The HFC network theoretically supports a wide transmission band that can be connected at a transmission rate of 9600 bps to 30 Mbps per channel with a 6 MHz bandwidth. In addition, in the HFC network, the optical cable section from the broadcasting station to the optical end station located at the subscriber center is formed in a star type, and the coaxial cable section from the optical end station to the subscriber is formed in a tree and branch type. The optical cable section consists of up and down optical transmission lines separately using optical transmission / receiving devices and optical cables. Separate the frequency bands to form up and down transmission paths. HFC network is a bi-directional system that can transmit the downlink signal from optical end station to subscriber (home) and the uplink signal transmitted from subscriber to optical end station. 1 CH) to transmit data such as internet. The uplink communication band (subscriber → broadcasting station) available for HFC network is 5 ~ 42 MHz, the downlink communication band (broadcasting station → subscriber) is 54 ~ 750 MHz, and the downlink frequency band of 550 ~ 750 MHz for future digital broadcasting service. Will be used. The advantages of HFC network are high speed internet service of up to 10Mbps and various multimedia services up to several hundred times faster than general telephone line modem or ISDN. In addition, the HFC network enables the Internet to be used at the same time the computer is turned on, like a LAN environment, so there is no need for a separate connection process.Because the broadband cable network is used, two-way service or T- Commerce implementation is easy.
