Qualification Tests
The AXS-200/635 is designed to test basic twisted pair quality, identify and
locate faults, perform advanced single-ended loop tests, and troubleshoot
noise and signal issues all the way up to 30 MHz in support of the VDSL2
standard. These measurements offer a quick and thorough method to
determine if the cable is capable of supporting xDSL technology. In
addition, it utilizes noise measurements, longitudinal balance tests, and
power spectral density tests to assist in the installation, maintenance, and
troubleshooting of copper cables.

POTS Dialing

another tester (or quiet termination or silent switchman) through a
switched circuit network. DTMF transmission is enabled via the AXS-200
keypad allowing you to place and receive POTS calls. The dialer can be
accessed from the Copper Qualification Tests pane and is also integrated
into individual test screens to give you quick access to the manual dialer
function, speed dial and last dialed lists, without exiting the current test
application.
