Broad Capabilities TVR10/100/1000 helps you locate faulty hubs, PCs or cable connections that are stopping or limiting the performance of your 10, 100 and 1000 Base-T LAN. You can even go inline between two LAN devices and determine the final negotiated speed and duplex of the link. Designed for both the LAN installer and repair person, it is useful documenting legacy LANs, installing and repairing LANs or adding equipment to existing LANs. The TVR10/100/1000 has been designed to test LAN devices and cabling to the 10, 100 and 1000 Base-T standard. This includes wiring paired to EIA(TIA)568B (also called AT&T258A or simply "AT&T"); and EIA(TIA)568A. EIA(TIA)568B is the most popular scheme for 10, 100 and 1000 Base-T cabling, while EIA(TIA)568A is the most popular scheme for ISDN cabling. USOC pairing (typically used for telephones) is not compatible with the Base-T standard and is therefore not tested by the TVR10/100/1000. To accomplish its goals, the TVR10/100/1000 performs tests that, prior to the TVR10/100/1000, required 7 different test sets. The multi-functionality is integrated to provide a combination of quick results that are not available in any other tester.The creative combination of these tests and other features yield an efficient, time-saving tester.
