This new, feature-rich test set is a necessity for all central office technicians. The TS25D Test Set features data lockout and lockout override, making you completely safe in talk or monitor mode. The DSL/POTS filtering technology allows you to safely draw dial tone without downing DSL.
A built-in tone generator simplifies wire identification with a probe. An amplified speaker makes monitoring the line hands-free, so you can keep working. The Talk Battery function provides voltage to carry voice conversation on non-powered pairs.
All in a compact unit with an oversized robust liquid crystal display (LCD) that makes the intuitive, common-sense menus easy-to-read and use.
Data Lockout
Data lockout protection prevents inadvertent disruption of data traffic by locking out technicians if data is present when moving from Monitor Mode to Talk Mode.
Data lockout override allows technicians to override the lockout circuit when attempting to pull dial tone from a noise line
