ST-330 Advanced VDSL2 Tester for xDSL Line Test And Maintenance Tools

SKU: 151229

The tester is designed for present all kinds of xDSL line including ADSL, ADSL2, ADSL2+, READSL, VDSL2. It not only can test xDSL physical layer parameter, but also can help you to confirm whether your line is proper to provide xDSL service. It also can evaluate your line quality. It also can have PPPoE dial, do IE network page browsing, and emulate user's PC+ Modem by inside Modem of ST330 to test the connection between user and ISP provider. You can have all kinds of test such as Ping, Ipconfig, Rouge, Tracert after successful dial. ST330 also can emulate the user's PC to test broadband IP line or have PPPoE dial by user's Modem to test the connection of IP network and Modem problem or to remove the problem arisen by computer.
