Overview – Multi-function ADSL/ADSL2+ Tester
The ADSL/ADSL2+ tester provides a test solution for ADSL, ADSL2, ADSL2+, and RE-ADSL installation, maintenance and measurement. It provides multiple test functions including upstream and downstream rate measurements, error counts, modem simulation and PING and Trace testing. It also delivers digital multi-meter (DMM) functionality to test subscriber telephone connectivity and line parameters. Test results and line parameter measurements are easily obtained with a push of the "Auto Test" key. Given its compact, handheld design and easy-to-use interface, this ADSL/ADSL2+ tester is an excellent tool for technician's field work.
