Le TALAN (Système de détection professionnel)

(En anglais seulement)

The TALAN incorporates several types of telephone line tests including common tests such as voltage, current, resistance, and capacitance tests, as well as NEW technology such as line NLJD, FDR Frequency Domain Reflectometry, and Digital Demodulation into a single piece of equipment. Additionally, the TALAN utilizes an automatic internal pair switching matrix to automatically perform tests on all pair combinations. The ability to perform several different tests allows the user to compare the results of multiple tests on multiple phone lines, quickly identifying any potentially threatening anomalies.

The TALAN represents a new breakthrough in telephone line testing. There currently is no other product available with the same capabilities.
