OVERALL MACHINE CONTROL July 6th, 1998

The MFCE contains most of the logical components for overall system control, and
direct interfaces to the IC cards, an RS232C interface, a G4 interface (CiG4-SV)
and a optional G3 interface (SG3-V.34).
The MFDU has interfaces to the power supply, sensors, drive components, and
optional equipment.

The RS232C interface may not be available in some models.

There are two cpus in the machine: the main cpu (SCP) on the MFCE and the
energy saver cpu on the MFDU. In energy saver mode, the main CPU switches off
and the energy saver CPU takes over.

The 2 MB (16Mbit) flash ROM contains the system software, which can be updated
through an IC card slot or from the remote control center using RDS.
The CGROM (Character Generation ROM) contains all the character fonts used on
the display and in reports.

The Panasonic MN195003MFL modem is used for all the communications (V.34,
V.17, V.29, V.27ter., and V.21). The 512kB flash ROM contains the modem
program.

The 2 MB DRAM is used for the SAF memory, ECM buffer memory, work area,
and page memory. The SAF memory can be extended by 2, 4, or 80 MB with an IC
memory card or a hard disk.

The 256 kB SRAM contains the user and system parameters. This can be
upgraded by 512 kB with the function upgrade card. These SRAMs are battery
backed-up.

* The SRAMs in the IC cards are battery backed up, in case the the machine is
turned off or the machine goes into the 2-watt energy saver. However, the data in
these SRAMs are not guaranteed if the card is disconnected from the machine.
Whenever the Fax On Demand card or Function Upgrade Card needs to be
removed for using the service tool, follow the instructions in section 4-1 to avoid
any data loss.

July 6th, 1998 SEP/SUB CODING

2. DETAILED SECTION DESCRIPTIONS

2.1 SEP/SUB CODING

Overview.

ITU-T introduced the following protocol signals in the T.30 recommendation in

1996. These signals enable confidential transmission and secured polling between
machines produced by different manufacturers.

SEP (Selective Polling): This signal informs the other terminal of the polling ID to
enable secured (ID) polling.
Up to 20 digits or characters can be sent in a SEP frame.

PWD (Password): This signal informs the other terminal of the password to enable
extra security.
Up to 20 digits or characters can be sent in a PWD frame.

SUB (Sub-address): This signal informs a sub-address of a destination. Some fax
servers use this information to route a received fax message to a specific address
in the local network.
Up to 20 digits or characters can be sent in a SUB frame.

Detailed

Descriptions

SID (Sender ID): This signal informs the other terminal of the sender ID to identify
the transmitter.
Up to 20 digits or characters can be sent in a SID frame.

The ITU-T recommendation only clarifies the requirements for the transmitting
terminal, and does not specify the requirements for the receiving terminal. How the
receiving terminal treats these signals varies with receiver terminal and
manufacturer.

NOTE:

This machine is not capable of receiving PWD and SID codes. If the

machine receives one of these frames, the machine ignores it.

SEP Signal:
When the Rx terminal receives the SEP signal with the NSC or DTC signal, the Rx
terminal switches over to secured polling transmission using the SEP ID. The SEP
(Selective polling) signal must contain four digits as an ID.

The Rx terminal automatically disconnects the line when any of the following
conditions occurs (error code 0-15).

· When the SEP ID is other than four digits.

· When anything other than numbers is included in the ID.

The communication becomes free polling when the SEP ID programmed is 0000.

PWD Signal:
When the PWD (password) signal is transmitted together with the SEP signal, the
PWD programmed is used as an ID code for stored ID override.

NOTE:

This machine is not capable of receiving PWD signal.

ID override.

Detailed

Descriptions

The SUB ID must contain four digits. The receiving terminal automatically
disconnects the line when any of the following conditions occurs (error code 0-15).

· When the SUB ID is other than four digits.

· When anything other than numbers is included in the ID.

· When a confidential ID is not programmed in the Rx terminal and when the

transmitted SUB ID is 0000.

A stored message can be printed using the (normal) confidential ID stored in the
machine when the SUB ID sent from the transmitter is 0000.

NOTE:

This machine is not capable of receiving SID signal.

JBIG COMPRESSION July 6th, 1998

2.2 JBIG COMPRESSION

JBIG (Joint Bi-Level Image Coding Expert Group) is a working group which
consists of members of ITU-T and ISO. The JBIG compression method allows data
compression of approximately 1.2 to 1.3 times the MMR method in text mode, and
2 to 10 times in halftone mode.

JBIG compression is only available in the optional G3 unit.

JBIG compression is disabled when any of the following conditions occurs.

· When JBIG compression is turned off by communication bit switch 00.

· When ECM is turned off by communication bit switch 01.

· When the receiving terminal does not have the JBIG feature.

· When the receiving terminal does not have the ECM feature.

There are two modes for JBIG compression;

· Standard mode: the transmitted data block consists of 128 lines.

· Optional mode: the transmitted data block consists of one page

(transmission speed with this mode is faster).

This machine supports both modes for transmission and reception. Which mode to
use for communication is determined during handshaking.

Cross reference:

Section 4.2 Bit switches

Communication bit switch 00 bit 5: JBIG reception mode

0: Standard mode only 1: Standard mode and optional mode (default)

Communication bit switch 00 bit 6: Priority of JBIG mode used for transmission

0: Standard mode 1: Optional mode (default)

Please note that transmission speed with the optional mode is faster.

Data Compression

JBIG compressed data is called the Bi-level Image Entity (BIE).
The BIE consists of a header frame (BIH: Bi-level Image Header) and compressed
data frame (BID: Bi-level Image Data).
The BIH frame contains information such as main scan width (pixels), sub scan
length, and compression mode (standard/optional) used.
The BID frame contains the actual data.

July 6th, 1998 MEMORY RECEPTION CONDITIONS

2.3 MEMORY RECEPTION CONDITIONS

User parameter switch 05 bit 1 allows the user to select how to treat an incoming
message that is without RTI or CSI.

User parameter switch 05 bit 1:

Memory reception if no RTI or CSI received 0: Possible, 1: Impossible
If 0 is selected, the machine receives all message regardless of RTI and CSI.
When this is set to 1 (default setting), the following bit switch works in combination
with the user parameter setting.
System bit switch 11 bit 6:

Conditions for memory reception if no RTI or CSI is received.

0: Memory reception is available only when RTI or CSI is received.

1: Memory reception is always available unless there is a mechanical (printer)

error.

The default setting is set to 1.
The default setting means that if the printer is working, all messages will be
received, regardless of the user parameter setting. But the user can decide
whether or not to print messages that have no RTI or CSI. However, when there is
a mechanical error in the printer, the machine rejects such a message because no
trace of the sender will be stored in the machine.

Detailed

Descriptions

This switch has been added from the LFO model.

2-5

LINE TYPE CHANGE July 6th, 1998

2.4 LINE TYPE CHANGE

When the machine is initially used only with the PSTN, the line type programmed
with phone numbers in Quick Dials and the Speed Dials is stored as PSTN G3.
Later, if the line connection is changed so that G3 is to be used only with the ISDN,
the communication port for all stored Quick and Speed Dials must be changed to
ISDN G3.
This feature allows the communication mode and port to be changed for all stored
numbers at once.

Procedure:

1) Change the data in the following RAM addresses.
4B5846(H) - Current line type setting.
4B5847(H) - Line type to be used after this procedure.

NOTE:

2) Turn the main switch off and on.

3) After this procedure, the data programmed automatically returns to FF(H).

The default setting for the above addresses are FF(H).

Then, the machine checks all phone numbers stored in Quick Dials, Speed
Dials, AI Redial, and Forwarding Stations. If the communication mode and
the port setting for a number is the same as specified for the current setting
in the above address, the machine changes these to the new setting.

Setting:

Bit 0 and 1: Communication mode

Bit 2 to 4: Communication port

Bit 5 to 7: Not used

Example:

If you wish to change the port setting from PSTN G3 to ISDN G3,
change the data to 00(H) (0000 0000) in the address 4B5846(H)
change the data to 0C(H) (00001100) in the address 4B5847(H)

Bit 1 0 Setting

0 0 G3
0 1 G4
1 0 Not used

Bit 4 3 2 Setting

0 0 0 PSTN1 (Standard G3)
0 0 1 PSTN2 (Optional G3 unit)
0 1 1 ISDN
1 0 0 Any available port
(This setting can be used only when an optional G3 or G4 unit is
installed in the machine.)
Other settings - Not used

NOTE:

Do not use this procedure if there are any files stored in the memory
awaiting transmission.
