programming process run smoothly, the Lucent Technologies personnel fill out
and refer to planning forms that record all of the system’s settings and features,
those that affect the whole system and those that affect individual extensions.
Lucent Technologies representatives use a book called
System Planning
as a
guide when filling out forms at the time of an installation or upgrade.
After the system is installed and programmed, copies of these completed planning
forms are available for you, as system manager, to use for reference and to
update as you make changes to the system. The forms are a complete record of
how your system is set up, so keep them in a safe place.
A list of the forms and a description of each form’s purpose is in Appendix D. One
of the forms, the Employee Communications Survey, is included in Appendix D.
Use this form if you need to conduct a survey of your users’ needs; for example, to
plan system modifications as your company’s needs expand.
If you have not received the completed planning forms for your system, contact
your Lucent Technologies representative. If you need a blank set of forms, call the
Lucent Technologies Customer Information Center at 1 800 457-1235.
Upgrading the System 1
There are two 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.
In Release 3.0 and later, an upgrade basically involves inserting a memory card
(similar to a computer diskette) 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 to you.
The memory cards are color-coded and have different titles to indicate their
contents and function:
■ Feature Upgrade Memory Card. Orange label with black bars; entitled
Forced Installation
. To upgrade your system to the latest release.
■ Maintenance Upgrade Memory Card. Orange label; entitled
Upgrade
Card
. To fix problems in the system.
NOTE:
A third type of memory card has a white label and is entitled
Translation
Card
. This memory card is used to back up and restore your system
programming as described in ‘‘
Backing Up the System’’ on page 6-38.
