Introduction
This chapter explains how to install the mail system hardware. It is intended for
qualified installers only.
WARNING:
Installation should be performed only by a qualified installer.
Preparing for Installation
Read this entire chapter before you begin the installation. Verify that you have
all the required components, and that your installation site meets the
requirements specified in this chapter.
You should have a copy of communications system Planning Form B1 that
shows extension assignments for the mail system hardware.
NOTE:
Outside of the United States, some telephone networks provide a tone
similar to the U.S. busy tone to signal that the far-end caller has hung-up.
If the mail system needs to respond to this signal, DIP switches need to
be reset on the voice processing cards before the system unit is
installed. See Chapter 7, “Upgrading the System.”
