The Lineman's Test Set is a professional piece of equipment designed for telephone installers, repair technicians, and phone system maintenance personnel. This durable, line-powered device is full of features for testing existing and newly installed communications systems for proper functionality.
The bright red handset is both impact and water resistant. The rubber-covered keypad and large slide switches are designed for use with gloves, making this a convenient tool for line workers. The large, heavy-duty alligator clips support five different types of wire connections, including a bed-of-nails and an insulation piercing spike. The connecting cord is covered in cloth for durability and is equipped with a strain-relief connection at the RJ11X connector. A heavy-duty, spring-loaded belt clip allows the handset to be conveniently hung from a maintenance belt.
The tester has a three-position volume switch, which can provide up to 12 dB of volume gain. The ring mode can be set to send either DTMF tones or rotary dial pulses. A three-position mode switch allows the tester to be set to Monitor, Ring, or Talk modes:
The Monitor mode provides a high-impedance coupling to the telephone line, allowing it to be monitored without interfering with existing conversations, data transmissions, or signalling.
The Ring mode allows the tester to be on-hook with an electronic ringer connected to the telephone line. This provides a low-impedance coupling to the telephone line for monitoring of optional line identification tones.
The Talk mode allows the technician to seize the line or initiate signalling. From this mode a number can be dialed using the keypad. Hanging up the line is as simple as switching to the Ring or Monitor mode.
The handset includes an automatic last-number redial function, which is capable of repeating up to 31 digits. It also features a number memory storage capability, allowing the technician to store up to 10 different numbers of up to 15 digits each, including the insertion of 3-second pauses for use with trunk lines. A pre-installed CR2032 lithium battery maintains the stored number memory and can be easily replaced by removing two screws and opening the handset.
To assist in line testing, the kit includes a 5-inch, 4-wire RJ11 test lead with spade lugs on the ends of each wire. Additionally, a 2.5mm headphone jack allows the technician to utilize a microphone/headset unit instead of the handset speaker and mic. When not in use, the headphone jack is protected from moisture with a rubber cover.
