2.4.1.

Physical Configuration

Each unit in MFP and physical boundaries within TOE are shown in Figure 2.

MFP consists of three board-units: controller board, control panel, and

facsimile card.

Controller board and control panel are connected via the internal interface where control data are

communicated.

In each of the following sets, the two are connected via the internal interface where document data

and control data are communicated:

- controller board and facsimile card

- controller board and IIT

- controller board and IOT

Controller board is a circuit board to control copy, printer, scanner, and facsimile functions of MFP.

This board has a network interface (Ethernet) and local interfaces (IEEE1284 and USB), and is

connected to IIT and IOT.

Control panel is for operating / making settings on copy, printer, scanner, and facsimile functions of

MFP.

Facsimile card is a circuit board to control facsimile communication using public telephone line

network.

TOE is a set of programs that are recorded in the system ROM that is mounted on the controller

board. Programs recorded in the ROM, which is a physical configuration item of TOE, are shown in

Table 1.
