The Fluke Networks TS54 TDR test set, 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 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. In monitor mode, the test set provides a high impedance coupling to monitor lines without disrupting service. When sw to talk mode, the data lockout feature tests the line for high-speed data signals and remains on hook and beeps if such signals are detected. The lockout can be overridden to pull dial tone from a noise line. Telephone test sets, also called butt sets, are used by telecom technicians to troubleshoot and maintain copper-wire voice-subscriber lines such as POTS (plain old telephone service) lines. TDRs are used by network and telecom technicians and installers to troubleshoot, maintain, and optimize performance of VDV (voice, data, and video) cabling. 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. The test set can be programmed to turn off automatically after a specified period (default setting is two minutes) of inactivity to conserve battery life, and is made of high-impact plastic. The high-visibility glow-in-the-dark keypad has 12 standard dialing keys including star and pound, and function keys to store, recall, and redial numbers and to pause for accessing a second dial tone when dialing through a PBX (private branch exchange), among other functions. A backlit LCD tracks functions and test status, and displays line voltage from 4 to 140VDC and current from 0 to 120mA. At voltages less than 4VDC and greater than 140VDC, the test set locks out and will not allow off-hook operation. It is made of high-impact plastic and turns on automatically when clipped to an active line. A spring-loaded belt clip at the base of the unit provides a secure hold on belt loops and D-rings, and a jack accommodates a headset (sold separately).

Datacom and telecom installation and test devices, such as toners and test sets, check cabling and wiring to help ensure proper connections and operation. Tone generator and probe sets, also called toners, are used to locate, trace, and isolate cables in copper media networks. Telephone test sets, also called butt sets, are specialized telephones that connect to telephone lines to check for proper operation and to isolate trouble. Some test sets incorporate a TDR (time-domain reflectometer) and toner for determining cable length and locating faults. While certain devices may be used on live networks, others are only suitable for inactive networks. Field technicians and installers use these devices to set up, maintain, and troubleshoot datacom and telecom cabling within a building or in outside (OSP) applications. Fluke Networks, a division of Fluke Corporation, manufactures tools and software for network deployment, performance management, and troubleshooting.
