When you’re working on active telephone circuits, the last thing you want is to accidentally disrupt digital services while troubleshooting a voice line. Tempo’s Nautilus DigAlert™ Telephone Test Sets are designed to help technicians confidently install, maintain, and service POTS lines without compromising existing broadband services such as ADSL, VDSL, and VDSL2.
The DigAlert™ Series continuously monitors for out-of-band digital signals, alerting technicians to the presence of live data services before testing begins. With super high-impedance monitoring, these test sets minimize the risk of interfering with parallel digital traffic, helping you protect customer service while diagnosing line conditions.
Built for demanding field environments, DigAlert™ test sets feature a rugged, weatherproof housing that stands up to rain, dust, and everyday jobsite abuse. High-voltage and excess-current protection, combined with audible warnings, provide an added layer of safety when working on live circuits. A lightweight, non-metallic quick-release belt clip keeps the unit secure and easily accessible throughout the workday.
Select models add enhanced functionality including loudspeaker monitoring, full hands-free conversation, and specialized versions for unique network requirements such as 12 kHz metering pulse detection or extended-bandwidth DigAlert detection for non-standard VDSL deployments. Whatever your application, the DigAlert™ family delivers the durability, protection, and performance technicians rely on every day.
Backed by Tempo’s industry-leading 3-year warranty, DigAlert™ Test Sets are built to keep you working confidently in the field.
