Upgrading the System 1
There are three types of system upgrades:
■ Feature Upgrade. To upgrade your system to the latest “release” or
version as soon as it becomes available. With little or no changes in your
existing equipment or wiring, your system can be easily adapted and
expanded as your company’s business needs change and grow.
■ Maintenance Upgrade. To fix problems in the system.
■ Processor Module Replacement. In some cases, upgrading the system
requires the replacement of the processor module.
In Release 3.0 and later, an upgrade basically involves inserting a memory card
(similar to a computer disk) into a slot on the system’s processor or “brain” (part of
the system’s
control unit
). For a feature upgrade, you need a new memory card;
for a maintenance upgrade, Lucent Technologies provides the memory card at no
cost.
For more information about upgrading your system, contact your Lucent
Technologies representative.
