The KE895 xDSL Check can activate the inactive DSLAM / ISAM at the remote end of a wired line to indicate the availability of a DSL service and the Annex variant via LED: Annex A / M (DSL via POTS), Annex B (DSL via ISDN) or Annex J (All-IP). All current xDSL services according to ITU-T G.441 are supported, for example ADSL or VDSL2 as well as the new SuperVectoring (VDSL 35b) and G.fast technology.
With the unique KE420 xDSL PROBE, wire pairs which carry active xDSL signals can be detected contactlessly. The active services are neither disturbed nor do they lose their connection. This way, the lines carrying an active xDSL signal can be easily determined in the Central Office (CO), at the Street Cabinet, at the house transfer point or in the building. Two LEDs indicate the activity from ADSL to ADSL2+, VDSL2 to Bandplan 17 and VDSL35b / G.fast. The brightness of the xDSL LED additionally indicates the signal strength.
The Ethernet link test enables active (patched) network connections to be detected and to be quickly and easily assigned to the corresponding port on the switch, in the LAN using the link blink function.
In addition, an integrated visible light source (VFL) is available for the visual inspection of optical fibres for daily work. It can be used to visually test singelmode / multimode fibre optic cables and other fibre optic components for breakage and continuity. Fibre optic cables in a bundle can be localized and assigned.
Overvoltage protection protects the device in case of accidental contact with live cables >100 V.
KE3150 has a cable finder function for identifying specific lines in telephone, data and coaxial as well as cables in voltage-free electrical installations. Cables can be located in ducts or walls. Wire pairs and even reversals and split pairs can be detected. A continuity test with resistance-dependent tone frequency helps to determine the copper cable condition.
