1-3. Detailed Features Description

1-3-1. Auto Select Mode

There are three reception modes, AUTO, TAM and FAX, one of which can be programmed in the Auto Select key on the operation panel using function 04 ‘‘SET FAX SWITCH’’. AUTO mode allows the machine to capture the line without any rings being heard by the users. Then, the machine starts to detect CNG for about 30 s while sending back ring-back tone or AVM (Artificial Voice Message) in one or two languages selected by the user. After that, it automatically receives the fax message or, if CNG is not detected, it calls the user by ringing from the speaker. TAM mode allows connection to telephone answering machines (TAM) connected on the same line. There are two types of TAM interface software used depending on the connection between the machine and the telephone answering machine. The first type of TAM interface is used in the countries where the TAM is connected to the machine as an external device. When the external device captures the line, the machine detects dc at the LIU. Then, the machine starts listening to the line. If the machine detects one or two CNG signals or a period of silence, the machine will capture the line and send CED/NSF/DIS to receive a fax message. The second type of TAM interface is prepared for the countries (e.g., Germany) where the machine is connected to the TAM as an external device. In this case, the machine cannot detect dc when the TAM goes off-hook. So, it monitors the ringing signal. After the programmed number of rings, the machine listens to the line for about 30 s. If the machine detects one or two CNG signals, the machine will capture the line and send CED/NSF/DIS to receive a fax message. With the second type of TAM interface, the machine cannot receive fax messages from machines which do not send a CNG.

FAX mode allows the machine to receive all incoming fax messages.

1-3-2. Authorized Reception

The machine automatically stores in RAM the TSI (or RTI) from the terminals programmed in the Quick Dials and Speed Dials, once the user sends a document to these terminals. Then, if Authorized Reception is switched on, the machine compares the TSI from the remote terminal with these TSIs memorized in the RAM, when the machine receives a fax call from any terminal. So, Authorized Reception prevents reception from terminals which are not programmed in the Quick/Speed Dials. If an unauthorized sender sends a fax message while this feature is switched on, the machine rejects the call and notifies the users by printing a rejection report with the unauthorized sender’s TSI or RTI.

1-3-3. Automatic Tx Speed Updating (AI Dial)

The machine memorizes the last five modem speeds that were used during transmission to the Forwarding terminal and each destination programmed in the Quick/Speed dials. Then, the machine chooses the most appropriate modem speed from the record for the next transmission, in order to reduce the time for modem rate fallback (approx. 5 s). This feature works only when the machine has more than two modem speed records fdor that destination. The modem speed is recorded in the memory if there are no error pages during transmission. This feature can work with other manufacturers’ terminals.

1-3-4. Page Retransmission in Normal Tx Mode - FAX240 only

In the normal transmission mode, the machine can retransmit failed pages as if in memory tx mode, if ECM is on. While sending the document, the machine backs up the document in the ECM memory in case page retransmission is needed. If the machine receives a negative code (RTN or PIN) after a page, the machine retransmits the whole page from the ECM memory.

1-3-5. Forwarding - FAX240 only

The machine can forward all received messages to the programmed Forwarding terminal. You can program the month, date and time for Forwarding to be switched on and for it to be switched off. Also, local printing of forwarded messages can be switched on and off.

3-1. BIT SWITCHES

WARNING

Do not adjust a bit switch that is described as "Not used", as this may cause the machine to

malfunction or to operate in a manner that is not accepted by local regulations.

Bit Switch 0

FUNCTION SETTINGS COMMENTS

0 Not used 1 Rx cable equalizer 0: Disabled

1: Enabled

Set this bit to 1 when there is a serious signal loss at higher frequencies during reception. The cable equalizer will amplify the signal in this range by +3 dBm.

2 DIS detections 0: Once

1: Twice

The machine will send DCS (G3 set-up signal) if it receives DIS. If echoes are frequent, setting this bit to 1 will allow the machine to wait for the second DIS before sending DCS.

3 TSI (RTI) printout on

received copies

0: Disabled 1: Enabled

If this bit is 1, the TSI or RTI received from the sender will be printed on the top of each page.

4 Burst error threshold/

error line ratio

0: 6 (12) [24] lines/10% 1: 3 (6) [12] lines/5%

If there are more consecutive error lines in the received page than the threshold specified by this bit, the page is rejected. Values in parenthesis ( ) are for Detail resolution, and those in square brackets [ ] are for Fine resolution. Also, if the number of error lines divided by the total number of lines reaches the ratio determined by this bit, the machine will send RTN to the other end. If you want to receive messages with fewer error lines, set this bit to 1.

5 Training error threshold 0: 4 bits

1: 1 bit

If the machine detects more errors during training than the number set by this bit, training fails and the machine will send FTT to ask the other terminal for modem rate shift-down. Set this bit to 1 if you want to receive messages at a more reliable modem speed.

6 Initial Rx modem rate 0: 9,600 bps

1: 4,800 bps

The setting of this bit is used to inform the sending machine of the initial starting modem rate for the machine in receive mode. If 9,600 bps presents a problem during reception, use 4,800 bps.

7 Back to back test 0: Disabled

1: Enabled

Set this bit to 1, when you want to test a back-toback communication.

Important Notice for Back-to-Back Mode

When in back-to-back mode, you cannot enter service mode unless you exit back-to-back mode first. This is because the machine starts communication if you press Start - Stop - and so on to enter service mode while you are still in back-to-back mode. Refer to the notice in section 2-2-12 for how to exit back-to-back mode.
