U-Test 300 Overview

The U-Test 300 family of xDSL testheads has been specifically designed to provide truly world class performance in Central Office based applications. This testhead provides the usual line fault detection and location, TDR, FDR and prequalification capabilities as one would expect from any world class testhead.

What distinguishes the U-Test 300 from our competitors products is its ability to provide critical xDSL specific measurements which are far beyond the current industry standard capabilities. This family of testheads has been specifically designed for today's xDSL service delivery problem set.

Supplied with brackets for standard 19" or ETSI rack mounting.
