Upgrading the System
7
Introduction
Customers with a two-port or four-port mail system may want to upgrade to a
four-port or six-port system to support more users or a greater volume of calls.
To increase the number of ports, a voice processing card must be added to the
mail system unit. Each voice processing card provides two ports.
This chapter contains instructions for adding a voice processing card. It is
intended for qualified installers only.
WARNING:
Only a qualified installer should open the system unit and add or replace
voice processing cards. Hazardous voltage is inside. Failure to comply
could cause electric shock.
