Power Systems
Avaya offers the following solutions to provide power for equipment and protection
from power disturbances or disasters:
• Uninterruptible Power Systems (UPS)
A UPS safeguards your DEFINITY ONE and associated applications from utility
power irregularities. During a power failure, the UPS battery activates and
supplies power for a limited amount of time.
• Surge Protectors
Surge protectors help protect PCs, fax machines, and other equipment from
electrical surge damage. Alternating Current (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 lines or via
wiring for phones that extend to or from another building.
• Terminal Power Supplies
Terminal Power Supplies provide local power for phones and adjuncts that
require additional power, such as DCP phones with headset adapters or adjunct
speakerphones.
