Power Systems
Lucent Technologies offers the following solutions to help provide protection from power disturbances and
disasters and to provide power for equipment:
• Uninterruptible Power Systems (UPS)
A UPS helps safeguard your DEFINITY ProLogix Solutions and associated
applications from utility power irregularities. During a power failure, the UPS
battery activates, supplying power for a limited amount of time.
• Surge Protectors
Surge protectors help protect PCs, fax machines, and other equipment from
electrical surge damage. AC Protectors prevent voltage surges from entering the
system via the AC utility line. Line Protectors prevent voltage surges from
entering the system via incoming central office (CO) lines or via wiring for
telephones (tip and ring) that extend to or from another building (In-Range Out-
of-Building).
• Terminal Power Supplies
Terminal Power Supplies provide local power for telephones and adjuncts that
require additional power (for example, DCP telephones with headset adapters
and adjunct speakerphones).
