ST335 is designed for meeting entire network requirement, which functions including xDSL test, LAN test and optical power test.

1. Summary

ST335 is designed for meeting entire network requirement, which functions including xDSL test, LAN test and optical power test..

ST335 can test all kinds of xDSL line (xDSL includes ADSL, ADSL2, ADSL2+, READSL etc.) It not only can test xDSL physical layer parameters to confirm whether the line is proper to provide xDSL service or not; but also evaluate the quality of the line; at the same time, perform PPPoE dial; browse IE webpage; completely emulate user’s PC+ Modem by its inside Modem to test the connectivity from user to ISP provider. After successful dial, network layer test which includes Ping, Ipconfig, Rouge, Tracert can be fulfilled. The tester can emulate the user’s PC to test broadband IP line or perform PPPoE dial through user’s Modem in order to test the connectivity of IP network and the problem of user’s Modem or eliminate malfunctions that leads to failing logon Web Pages caused by user’s PC.
