PURPOSE: An internetworking equipment using an SDSL(Symmetric Digital Subscriber Line) is provided to use an HDLC(High bit rate Digital Subscriber Line) controller, a high capacity packet processor, and a PCI(Peripheral Component Interconnect) bus, so as to construct a stable network communication environment. CONSTITUTION: The second SDSL modems(130) connected to subscribers are converted into data information having a bit serial type from SDSL modem signals transmitted from the subscribers. An HDLC controller(140) has many input ports connected to the second SDSL modems(130), and packetizes a digital bit serial transmitted from the second SDSL modems(130), then controls packets. A high capacity packet processor(160) controls data information transmitted from the HDLC controller(140) at a high speed. A PCI bus(150) processes the data information as bus types.
