SW-A1 No. 1 Protect from echo Used to protect from echo in reception. SW-A1 No. 2 Forced 4800BPS reception When line conditions warrant that receptions take place at 4800 BPS repeatedly. It may improve the success of receptions by setting at 4800BPS. This improves the receiving document quality and reduces handshake time due to fallback during training. SW-A1 No. 3 Footer print When set to "1", the date of reception, the sender machine No., and the page No. are automatically recorded at the end of reception. SW-A1 No. 4 Length limitation of copy/send/receive Used to set the maximum page length. To avoid possible paper jam, the page length is normally limited to 0.6 meter for copy or transmit, and 1.5 meters for receive. It is possible to set it to "No limit" to transmit a long document, such as a computer print form, etc. (In this case, the receiver must also be set to no limit.) SW-A1 No. 5 CSI transmission (CSI TRANSMISSION) is a switch to set whether the machine sends or does not send the signal (CSI signal) informing its own telephone No. to the remote fax machine when information is received. When "nonsending" is set, the telephone No. is not output on the remote transmitting machine if the remote transmitting machine has the function to display or print the telephone No. of receiving machine, using this CSI signal. SW-A1 No. 6 DIS receive acknowledgment during G3 transmission Used to make a choice of whether reception of DIS (NSF) is acknowledged after receiving two DISs (NSFs) or receiving one DIS (two NSFs). It may be useful for overseas communication to avoid an echo suppression problem, if set to 1. SW-A1 No. 7 Non-modulated carrier for V29 transmission modem Though transmission of a non-modulated carrier is not required for transmission by the V29 modem according to the CCITT recommendation, it may be permitted to a send non-modulated carrier before the image signal to avoid and echo suppression problem. It may be useful for overseas communication to avoid an echo suppression problem, if set to 1. SW-A1 No. 8 EOL (End Of Line) detect timer Used to make a choice of whether to use the 25-second or 13-second timer for detection of EOL. This is effective to override communication failures with some facsimile models that have longer EOL detection. SW-A2 No. 1 ~ No. 4 Modem speed Used to set determine the initial modem speed. The default is 9600BPS. It may be necessary to program it to a slower speed when frequent line fallback is encountered, in order to save the time required for fallback procedure. SW-A2 No. 5 Senders information transmit (SENDERS INFORMATION TRANSMISSION) is a switch to set the function to print the content of HEADER PRINT described in the passcode list at the front end of receivers original when original is sent to the remote machine. If this switch is set to "NO", the HEADER PRINT is not output at the receiving machine. SW-A2 No. 6 H2 mode Used to determine reception of H2 mode (15 sec transmission mode).

SW-A3 No. 4 ~ No. 8 Reserved Set to "0". SW-A4 No. 1 ~ No. 5 Signal transmission level Used to control the signal transmission level in the range of-0dB to31dB. The factory setting is at -11dB (MODEM output). SW-A4 No. 6 Protocol monitor (Error print) If set to "1", protocol is printed at communication error. SW-A4 No. 7 Protocol monitor Normally set to "0". If set to "1", communication can be checked, in case of trouble, without using a G3 tester or other tools. When communication FSK data transmission or reception is made, the data is taken into the buffer. When communication is finished, the data is analyzed and printed out. When data is received with the line monitor (SW-A4 No. 8) set to "1" the reception level is also printed out. SW-A4 No. 8 Line monitor Normally set to "0". If set to "1", the transmission speed and the reception level are displayed on the LCD. Used for line tests. SW-A5 No. 1, No. 2 Digital line equalization setting (Reception) Line equalization when reception is to be set according to the line characteristics. Setting should be made according to distance between the telephone and the telephone company central switching station. SW-A5 No. 3, No. 4 Reserved Set to "0". SW-A5 No. 5, No. 6 Digital cable equalizer setting (Reception for Caller ID) Line equalization when reception for CALLER ID is to be set according to the line characteristics. Setting should be made according to distance between the telephone and the telephone company central switching station. SW-A5 No. 7 Error criterion Used to select error criterion for sending back RTN when receiving image data. SW-A5 No. 8 Anti junk fax check When using the Anti junk fax function, set to "1". SW-A2 No. 7 Communication error treatment in RTN sending mode (Reception) Used to determine communication error treatment when RTN is sent by occurrence of a received image error in G3 reception. When it is set to "1", communication error is judged as no error. SW-A2 No. 8 CNG transmission When set to "0" , this model allows CNG transmission by pressing the Start key in the key pad dialing mode. When set to "1", CNG transmission in the key pad dialing mode cannot be performed. In either case, CNG transmission can be performed in the auto dial mode. SW-A3 No. 1, No. 2 CED tone signal interval For international communication, the 2100Hz CED tone may act as an echo suppression switch, causing a communication problem. Though SW-A3 No. 1 and No. 2 are normally set to 0, it should be changed this time between the CED tone signal to eliminate the communication problem caused by echo.

CHAPTER 5. CIRCUIT DESCRIPTION

[1] Circuit description

1. General description
The compact design of the control PWB is obtained by using ROCKWELL (CONEXANT) fax engine in the main control section and high density printing of surface mounting parts. Each PWB is independent according to its function as shown in Fig. 1.
3. Operational description
Operational descriptions are given below:

Transmission operation

When a document is loaded in standby mode, the state of the document sensor is sensed via the 1 chip fax engine (FC100M). If the sensor signal was on, the motor is started to bring the document into the standby position. With depression of the START key in the offhook state, transmission takes place. Then, the procedure is sent out from the modem and the motor is rotated to move the document down to the scan line. In the scan processor, the signal scanned by the CIS is sent to the internal image processor and the AD converter to convert the analog signal into binary data. This binary data is transferred from the scan processor to the image buffer within the RAM and encoded and stored in the transmit buffer of the RAM. The data is then converted from parallel to serial form by the modem where the serial data is modulated and sent onto the line.

INTRODUCTION

The ROCKWELL (CONEXANT) R96V24 MONOFAX facsimile modem family provides 9600 bps half-duplex capability with options supporting DigiTalk voice and ADPCM audio codecs, DigiTalk full-duplex speakerphone, and V.23 full-duplex. The modem models are identified in Table 1-1. These functions are supplied in a single VLSI device or two-device set (for speakerphone). The MDP (modem data pump) is packaged in a 100-pin PQFP. The MDP contains an internal integrated analog codec (IIA) and is pin-compatible with the R96V24 MONOFAX modems. This device family enables cost-effective development of a common facsimile machine design with digital answering machine and/or full-duplex speakerphone. The modem can operate at 9600, 7200, 4800, 2400, or 300 bps, and can perform HDLC framing per T.30 at all rates. A programmable DTMF detector, three programmable tone detectors, and Caller ID demodulator are provided. The DigiTalk V24 voice coder/decoder (codec) compresses voice at an average rate of 2.9 kbps or at a fixed rate of 4.7 kbps with near toll quality playback. An average rate of 2.9 kbps provides 24 minutes of stored voice messages in 4 Mbits of memory. This voice codec allows the host controller to efficiently store and playback digital incoming messages (ICMs) and outgoing messages (OGMs). The ADPCM audio codec compresses audio signals (e.g., music/voice) at 32 kbps or 24 kbps for highest fidelity coding and reproduction. Selectable error correction coding allows storage in audio grade RAMs (ARAMs). Echo cancellation techniques employed during playback allow DTMF and tone detection during voice/audio codec operation to support user selectable features. The coder can record messages from either the IIA or XIA. Dual/single tone transmission is available when the decoder is disabled.

2) Circuit description

The TEL/LIU PWB is composed of the following 10 blocks. 1. Surge protection circuit 2. Noise filter 3. Dial pulse generation circuit 4. CML relay 5. Matching transformer 6. Hybrid circuit 7. Signal selection 8. Sensor circuit 9. Cl detection circuit 10. Power supply and bias circuit
3) Block description 1. Surge Protection circuit This circuit protects the circuit from the surge voltage occurring on the telephone line.
The AR1, AR2 protects the circuit from the 425V or higher line

surge voltages.

2. Noise filter The noise filter comprises the RF choke coil, L6, L7 and L8. 3. Dial pulse generation circuit The pulse dial generation circuit comprises the photo-coupler PC2, PC3, polarity guard REC1, and resistor R1. The photo-coupler PC3 shunts the line current using the DP signal before transmitting the dial signal, then turns off the CML relay. After the pulse dial signal is transmitted by turning on/off the DP signal, the CML relay is turned on again. 4. CML relay The CML relay switches over connection to the matching transformer T1 while the FAX or built-in telephone is being used. 5. Matching transformer The matching transformer performs electrical insulation from the telephone line and impedance matching for transmitting the TEL/FAX signal. 6. Hybrid circuit The hybrid circuit performs 2-wire-to-4-wire conversion using the IC102 of operational amplifier, transmits the voice transmission signal to the line, and feeds back the voice signal to the voice reception circuit as the side tone. 8. Sensor circuit For the recording paper sensor (PE), when there is recording paper, the photo transistor in the light receiving side is ON and the detection level is LOW. When there is no recording paper, the photo transistor in the light receiving side is OFF and the detection level is HIGH. 9. CI detection circuit The CI detection circuit detects the CI signals. A CI signal, which is provided to the photo-coupler PC6 through the C3 (0.68 F), R3 (1 K), and ZD2 when the ring signal is inputted from the telephone line. 10. Power supply and bias circuits The voltages of +5V and +24VA are supplied from the control PWB unit. TXCONT
