The TS54 from Fluke Networks is a three-in-one—TDR, toner and pair identifier—premium, VDV test set. It is available with various line cord connectors to suit specific applications, incorporates a TDR, tone generator, and telephone test set into one tool for testing VDV cabling as well as POTS quality on live DSL lines without disrupting data services.
The TDR (time-domain reflectometer) measures cable length and locates faults on virtually all types of cable including twisted pair, coaxial, and parallel conductors, finding the distance to open and short circuits in up to 3,000' of cabling.
It has an adjustable VOP (velocity of propagation) setting to optimize the accuracy of fault location and cable length measurements. The analog tone generator sends a signal through wires for locating and tracing wires with a probe (sold separately), and has five distinct SmartTone cadences for isolating individual wire pairs.
The telephone test set is designed for outside plant use to detect dial tone and polarity, place and receive calls, indicate line voltage and current, and verify caller ID and call waiting caller ID services; has a two-way, adjustable-volume speakerphone for hands-free conversation during testing; monitors lines without disrupting service; locks out off-hook testing when high-speed data is detected; and stores up to nine 23-digit telephone numbers which can be speed-dialed via the keypad. It provides tone or pulse operation.
The test set has two basic modes of operation: talk mode for off-hook operations including verifying dialing and receiving calls, and monitor mode for on-hook operations including checking for an idle line, listening for line noise, measuring DC voltage on the line, and capturing DTMF (dual-tone multi-frequency) tones to check for proper signaling.
This test set meets IEC (International Electrotechnical Commission) safety standard 61010-1:2010 and is rated for CAT I installations to 300VDC, which covers equipment on circuits not directly connected to mains.
It passes a 20' (6m) drop test and is Ingress Protection certified IP64 for protection against dust and splashed water.
