XDSL Testers
-
GAOTek offers a wide range of xDSL testers that are specifically manufactured to meet the requirement of xDSL testing, along with ADSL, ADSL2, ADSL2+, READSL, and VDSL for sale to the United States, Canada and Globally. They are mainly used by field operators for telecommunication installation, troubleshooting of xDSL network and maintenance. xDSL testers not only tests the physical structure but also evaluates whether the line is fit for xDSL service and consider the quality of service. The devices can be operated in “ATUR+PC” simulation without any external ADSL2+/VDSL2 modem or computer as they can be easily operated by digital multi-meter. These devices evaluate line quality, carry out PPPoE dial-up, suggest web page browsing to determine the connection to the ISP, and emulates a PC+ modem. These testing devices also help with PING, IP config, route and tracert tests. Moreover, these devices can also function as a computer for examining broadband IP lines or begin a PPPoE dial-up to determine IP network connection and troubleshooting a computer or modem issues.
