The ADTRAN Total Reach Standalone Isolator Unit with Battery Back-up provides high voltage isolation between an ISDN line and the network termination (NT) equipment at the customer’s location. It also provides isolation for an Adtran Total Reach ISDN or Total Reach DDS (Ex: 56K DDS) circuit.
The unit consists of an isolator card mounted inside a small compact enclosure. The enclosure is molded from fiberglass, making it a lightweight, flame retardant product of high dielectric strength. Its fiberglass body limits the possibility of many kinds of infiltration while providing reliable isolation from external ground potentials.
