Fluke Networks 22801009 TS22A Telephone Test Set Angled Bed of Nails Clips

The Fluke Networks TS22A telephone test set, available with various line cord connectors to suit specific applications, detects dial tone and polarity; places and receives calls; has a two-way speakerphone with low, medium, and high volume settings for hands-free conversation during testing of telephone lines; monitors lines without disrupting service; and stores up to nine 18-digit telephone numbers which can be speed-dialed via the keypad. It provides tone or pulse operation. A pair of LEDs on the front of the unit indicates line polarity when off hook. The test set passes a 20-foot (6 m) drop test, withstands moisture in severe weather conditions, resists radio frequency interference (RFI), and has over-voltage and over-current protection. The 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). A two-position switch allows selection of monitor mode for high-impedance monitoring without disrupting service, and talk mode for dialing and talking. The test set turns off automatically after five minutes of inactivity to conserve battery life, and is made of high-impact polycarbonate that provides excellent insulating properties. Its contoured hand grip has a non-slip pad that rests on the shoulder to enable hands-free operation. A spring-loaded belt clip at the base of the unit provides a secure hold on belt loops and D-rings. Additional specifications include various environmental operating conditions. Telephone test sets, also called butt sets, are used by telecom technicians to troubleshoot and maintain copper-wire voice-subscriber lines.

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

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 plant (OSP) applications.
