Hobbes, the leader in network testing, provides a simple solution to your testing needs by allowing you to connect all types of twisted-pair cabling (such as the 258A eight-wire system specified by AT&T) and test it for continuity status with just the press of a button.
The Network Cable Tester (251450-R) also features with a set of dip switch and jumpers, which you can test different pin out configurations and perform necessary rewiring if necessary.
This model is also RoHS (Restriction of Hazardous Substances) compliant making it a perfect solution in European countries that require this standard.
