Power
DEFINITY ECS can accept a variety of AC or DC power. The system can operate without
requiring a power transformer in almost any part of the world.
During a power outage, individual cabinets (Single or Multi-Carrier) will continue to
function for up to 15 seconds; the Multi-Carrier Cabinet will function for up to 10 minutes
without power, depending on configuration. Optionally, an Uninterruptible Power Supply
can protect a DEFINITY ECS system from under or over-voltage conditions, line
frequency fluctuations, and power blackout of short duration. A battery backup system
can be used to provide power for up to 8 hours, depending on the type and quantity of
circuit packs and amount of traffic during the holdover period.
Software
All DEFINITY ECS systems throughout the world use the same basic software. In
addition to the basic software, various optional packages can enhance the capabilities of
the system. Some of the capabilities described in this document require optional
software. See your Account Representative for more information. The basic software is a
prerequisite for all the optional packages.
