Learn how to take the most important diagnostic readings when working with Analog Telephone Lines. These readings apply to real POTS lines as well as "fake" analog lines coming out of an ATA, MagicJack, Ooma or Cable box as well.
We'll demonstrate how to use a digital multimeter (DVOM) to check Loop Current, Talk Battery, Ring Voltage, Ring Current, and check for Induced AC and Longitudinal Imbalance.
This is an advanced video for Telecom Technicians. If you run into a problem with Analog equipment and you need to make it work right, this is where to start.
