Description

  The present invention relates to a system that can provide the Internet and a general telephone (PSTN) at the same time, and more particularly, to a system that can simultaneously provide the above-mentioned services through one connection line.

  As a device that provides the Internet and a general telephone at the same time, there is a DSLAM device that provides an ADSL or VDSL service. DSLAM equipment is a form of service that uses a copper wire to connect to a local telecommunication office on a one-to-one basis.DMT (Discrete Multi-Tone) method is also applied to modulation and demodulation methods to transmit voice and data. It is a technology that sends and separates and connects through a splitter, and was able to simultaneously service a general telephone and the Internet using copper wires embedded in the past where high-speed data exchange was not required. However, DSLAM equipment that provides ADSL or VDSL service has a problem that there is a limit to increase speed when trying to apply to high speed data packet service by using copper wire, and When using a copper wire, the connection distance is limited, and it is possible to connect only to a certain area when attempting a long distance connection. The longer the distance, the lower the transmission speed according to the modulation / demodulation method. In addition, there is a problem that the existing copper wire becomes obsolete by using the existing copper wire, and the maintenance management cost is increased.

  On the other hand, when the optical internet service is provided at home, the optical internet service cannot be connected to the ordinary telephone service, and the internet telephone is newly developed to provide a function similar to the ordinary telephone on the internet. . Internet telephones compress PCM voice signals using a voice codec (codec) and change them into packets, which are switched by an internet service device to provide an internet voice telephone service. By the way, there is a problem that a conventional telephone cannot be connected to a pot for connecting an Internet telephone, and a large number of Internet telephones cannot be connected to one pot.
