ADSL2+ Tester
GAO 2048

Overview – ADSL2+ Tester (GAO2048)

This portable ADSL2+ Tester is especially useful for installation, maintenance and its compact size and rugged design make it a perfect tool for ADSL technicians and engineers for field use. The tester is commonly used as a digital multi-meter to test subscriber telephone connectivity and line parameters. It is suitable for tier-1 ADSL applications. The ADSL2+ Tester provides upstream and downstream rate measurement, error count, digital multi meter (DMM) test functions, modem simulation, and PING and Trace testing.
