		<P1><![CDATA[Technically speaking, the System III is the name given to a single entire receiver configuration. It includes the following hardware components.<br>A receiver that resides in two 19-inch metal racks that incorporates the LCD and backplane.<br>The Central Processing Module that controls the overall operation of the System III receiver, which includes multiplexing alarm signals from the line cards and sending them to the appropriate outputs.<br>A backplane providing interconnection of modules and communication interface.<br>A power supply unit that provides power to all modules of the system.<br>Up to 24 line cards, each line card monitors one telephone line and stores up to 64 profiles for data management. Each line card has two internal buffers. One for printer messages and the other for automation messages in the event one fails.<br>A power converter that provides 5V DC power output required for the line cards. A slot exists for a second voltage converter. In the event of a failure, the redundant voltage converter can be removed and replaced without powering down the unit.<br>The power supply controller monitors the states of the power and fan for each rack and provides power for the high intensity LCD display.<br>The BP3X Interface Module is also a 19-inch rack mounted panel the interfaces with the System III Telco connector to provide twenty-four Rj-11 connectors for direct connection to the telephone lines.<br>The System III also has the capability of receiving alarm messages via Internet connection.<br>You will review the each component on more detail on the following screens.]]></P1>
