Subscriber line using external department {Subscriber line using external department}

The present invention relates to a subscriber network, and more particularly, to a subscriber network using an external end station capable of improving line quality through stabilization of a communication network.

The current Internet service is increasing in importance as a communication service that can collect and transmit various information in real time. One important advantage of Internet services is the ability to transfer large amounts of information at high speed. However, as the number of Internet users and Internet traffic increase, the data transmission speed is gradually slowing down. Therefore, various methods for increasing the transmission speed have been devised, and among them, research on the internet network using the optical communication network is active.

On the other hand, the subscriber line (Subscriber Line) refers to the section connecting the subscriber and the telephone station to the network to provide a communication service. A traditional telephone subscriber network connects subscriber lines with line facilities through various channels outside the telephone station through the Main Distrbution Facility (MDF) and finally with subscriber terminals.
