Switchable transmission device for VDSL CO/CPE circuit

A switchable transmission device for the VDSL CO/CPE circuit, which integrates a CO transmission circuit and a CPE transmission circuit into a device by a hybrid filtering means, comprising:

• a VDSL mastering unit, which is a chip set used for receiving a switching signal and switching the switchable transmission device to the CO end or the CPE end;
• a CO/CPE circuit switching unit, which is a switch of a switching circuit coupled to VDSL mastering unit, for producing the switching signal;
• a status displaying unit electrically connected to the CO/CPE circuit switching unit and the VDSL mastering unit, so as to display an operating status of the switchable transmission device for the VDSL CO/CPE circuit;
• a CO/CPE signal filtering unit, which is a hybrid filtering unit integrating the filtering circuits in the CO end and in the CPE end, coupled to the VDSL mastering unit for filtering the signal of the switchable transmission device for the VDSL CO end or the CPE end after switching;
• a telephone line port, which is a communication port in compliance with an RJ-11 format, coupled to the CO/CPE signal filtering unit and linking to an external network via a telephone line;
• and
• an Ethernet port coupled to VDSL mastering unit, and using an RJ-45 cable to link to a local area network.
