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.
