GAO Tek Rolls Out GAO332 ADSL2+ Tester

GAO Tek Inc. has released a new ADSL Tester – GAO332 ADSL2+ Tester. GAO332 ADSL2+ Tester is designed to meet urgent needs for xDSL tests. And xDSL includes ADSL, ADSL2, ADSL2+ and READSL. It is a total solution for xDSL installation & maintenance.

With rapid development of xDSL broadband service, installation & maintenance becomes critical. And xDSL service is more complicated than traditional telephone service. To own a compact, portable, simple tool will make the installation and maintenance work easier. GAO332 is a necessary assistant to the top-notch lineman.

Now some xDSL testers on market are very complicated and require the user to have rich signal emulation knowledge and network analysis ability. Additionally their prices are generally high. An ISP could only buy several sets and ask high network analysis engineer to operate it. It is actually not a suitable tool for the installation and maintenance worker.

GAO332 ADSL2+ Tester can not only test physical parameters, but can also help to judge whether a line is fit for xDSL service and evaluate service quality. In fact the successful craftsman does not need to know a lot of line parameters and specifications. Their most important task is to determine the service quality and locate the fault points. With the help of GAO332 every forefront workman is equal to the task. Simultaneously our tester can also perform PPPoE dialing through the built-in Modem and validate the connection between user and ISP through emulating the user PC + Modem.

GAO332 uses a LCD display and user friendly menu operation. It can display the test results directly and will improve xDSL broadband service greatly. It is the best choice to move your xDSL to the forefront.
