BI Communications LanCaster Network Cable Tester Troubleshooting is a professional Structured Cabling Tester and Trouble Shooter designed to speed up the on-site testing of data and voice networks, and the production testing of cable assemblies. The LanCaster identifies all common faults, including split pairs, on wiring schemes installed to TIA568 A/B, USOC and ISDN standards. In addition to this the LanCaster can inform the user which end of the installed link contains certain types of fault, enabling rapid location and correction. Before checking an installed wiring network, the LanCaster will alert the operator if any telephone services are active on the cable under test and can test for, and indicate, any other active services (10Mb/s, 100Mb/s, Token Ring, etc), to prevent accidental testing of a live network. The LanCaster also measures the length of cable or link under test, and has a built in tone generator, detectable with a standard probe, for cable tracing and identification. The LanCaster is supplied complete with 1 active remote unit / office identifier, and there are a further 15 available as optional accessories. These can be used to identify different radial circuits at the network hub. The Lancaster has the same features as Microscanner Pro with better price. Made in England.
