Chapter 2 MODEM AND FAX BASICS This chapter is intended for those readers who want to know the details behind modem and fax operations; what's going on behind the scenes. In addition to introducing basic modem and fax terminology, this chapter helps users to understand and be able to utilize the available features. Experienced modem and fax users may wish to skip this chapter. Modem Modem is a compound word of MOdulator and DEModulator. A modem is used for computer communications. Refer to Fig. 2.
RS-232C or EIA-232D/E RS-232C is the Recommended Standard (RS) of the Electronic Industries Association (EIA), defining the serial communication interface between a DTE and a DCE. The 232 is basically a serial number for the defined standard. Sometimes it is necessary to redefine a standard, or to revise it. The most commonly used revision of the RS-232 standard is the "C" revision. For the "D" revision, the prefix was changed to EIA.
A PC's COM1 and COM2 are asynchronous serial ports. Most PCs' and Unix systems' serial data communications are asynchronous. The serial data communication on an IBM mainframe or mini is synchronous. UART A UART (Universal Asynchronous Receiver Transmitter) is the device used in a DTE or DCE for asynchronous data reception and transmission. The standard UART device used in PCs is of the NS16450 type.
nal transmission in both directions. This is the type of phone service most people have in their home or office. Since the same two wires are used for both transmitting and receiving signals, an echo of the transmitting signal will also be received and it is the modem receiver's task to remove the echo before demodulation. Leased-line phone service is also available from phone companies in a 4-wire form.
BRI BRI, Basic Rate Interface, is the ISDN service provided to a normal home or office. It consists of 2B+D data channels. A D channel offers a speed of 16Kbps for signaling information transmission. Each B channel is for user data transmission at 64Kbps. Each B channel can be used independently for voice or data transmission. A user can place two independent calls through a BRI interface simultaneously. U- or S-Interface ISDN signal transmission is digital from end to end.
V.25bis Command Set V.25bis is a set of auto-dialing commands defined by the ITU-T. V.25bis supports both synchronous and asynchronous data interfaces and is mainly used in Europe and in IBM mainframe or mini-environments which use synchronous communication. Error Correction In synchronous data communication, data is checked and corrected in the host by the so-called "link layer protocol" to ensure data integrity. Normally, no data checking is provided in the host for asynchronous data communication.
V.42bis and V.42 V.42bis and V.42 are data compression and error correction standards set by the ITU-T. V.42bis has a better data compression efficiency than MNP-5 and is a more advanced compression scheme. V.42bis is used with V.42 for error correction. Xmodem, Ymodem, and Zmodem These are file transfer protocols. They do error checking and ensure data integrity of the file transferred. Some variations of these protocols also appear, like Xmodem-1k, Ymodem-G, etc.
Modem as a Fax Modems can also be designed to include a fax transmitting and receiving function similar to a fax card. Since the modem's interface with the computer is the standard serial RS-232 interface, this interface is used for both modem and fax operations. Since the data throughput of a serial RS-232 interface is limited, only compressed fax image data should be carried through this serial interface. Fax image coding and decoding must be done in the computer.
Distinctive Ring This is a service available from some phone companies in some areas of the USA and elsewhere. You can have several phone numbers on the same subscriber phone line. The phone company sends a different ring signal for each phone number assigned to the same line. You can have your phone equipment answer only a certain type of ring corresponding to a certain phone number. ZyXEL modems can be set to answer on one or a combination of four types of ring signals.
Automatic Redial / Call Hunting Most modems will automatically redial a telephone number several times if a connection could not be established on the first try. The modems of the 2864 series also offer the ability to do cyclic redials of a set of up to 10 different numbers. Modem Approval and Legal Matters In some countries the PTT authorities require modems to conform to a set of specific rules, e.g.
Chapter 3 MODEM INSTALLATION This chapter describes the panel function of the 2864 series modems and serves as their installation guide. External Modems A shielded RS-232 cable is required to ensure compliance with FCC Part 15, and it is the responsibility of the user to provide and use a shielded RS-232 cable. Make sure your installation site is clean and well ventilated.

Front Panel Switches There are two toggle switches on the Elite 2864 front panel. D/V (DATA/VOICE) A toggle switch that switches the modem on-line (off-hook DATA mode) or off-line (on-hook, Voice or Talk mode, the telephone set is connected to the line). The OH LED indicator will be turned on and off by this switch. If S35 bit 4 is set (S35.4=1), pressing this switch will make the modem go off-hook and dial the default number.
The following table explains the connectors on the rear panel: POWER JACK PARALLEL SERIAL LINE PHONE Input terminal for power adapter. There is no power switch on the modem.The power switch on the power adapter will turn off the power adapter and shut off power to the modem. Always turn off the power adapter before connecting or disconnecting power. For additional safety against possible damage, don’t turn on the power with the parallel port connected to a piece of equipment which is under power.
Elite 2864L Front Panel The Elite 2864L's front panel is exactly the same as the Elite 2864's except that the Elite 2864L has an LL LED indicator instead of the VO indicator. LL Leased-Line indicator; lights up when the modem is operating in the leased-line mode. Elite 2864L Rear Panel The Elite 2864L has a LEASED line jack and a DIAL-UP line jack. The LEASED line jack is a JM8 leased-line connector for a 2 or 4-wire leased-line connection. Pin assignments for the JM8 jack are listed in appendix B.
Supreme 2864L Front Panel Fig. 3.3 shows the front panel of the Supreme 2864L. There are 10 LED indicators, a 20×2 LCD display, and four directional key switches. Fig. 3.3: The Supreme 2864L front panel The 10 LED indicators are labeled as PWR, OH, AA, DTR/POL, RTS/PPE, TXD, RXD, SP, PRP, and PCP. The meaning of these LED indicators can be found on page 3-2 to page 3-3 where the LED indicators of the same label are explained for the Elite 2864 model.
Connecting the Supreme 2864L Please refer to the section Connecting the Elite 2864 on page 3–5. The descriptions therein also apply to connecting the Supreme 2864L. The Supreme 2864L has an additional leased-line jack for 2/4-wire leased line connection. Leave the leased-line jack unconnected if the leased line is not used. Turning on the Supreme 2864L Turn on the power switch on the power adapter to turn on the modem.
Omni 288P and Omni 288S The Omni models are V.34 modems with V.34/fax/voice capability, but without the ISDN capability. The Omni 288P includes a parallel port as DTE interface, the Omni 288S includes a serial port as DTE interface. Omni 288P Front Panel Fig. 3.3 shows the front panel of the Omni 288P. There are 13 LED indicators and one key switch. Fig. 3.6: The Omni 288P front panel The 13 LED indicators are labeled as V34, V32b, AA, CD, TXD, RCD, DTR/POL, DSR/PSL, PRP, PCP, EC, SQ, and OH.
as on the Omni 288P except that the Omni 288S has two LED indicators labeled RTS and CTS instead of PRP and PCP as found on the Omni 288P. Fig. 3.7The Omni 288S front panel The meaning of the Omni 288S LED indicators can be found in the table beginning on page 3-2 where the LED indicators of the same label are explained for the Elite 2864 model. Omni 288P Rear Panel Fig. 3.8 shows the rear panel of the Omni 288P. Fig. 3.
TO DTE MIC SPK LINE PHONE This is a parallel port DB25 male connector for connecting to a PC’s parallel port or a printer’s Centronics compatible port. Microphone jack to plug in an external microphone. Used for voice recording purposes. Speaker jack to connect an external 8 Ohm speaker. An external speaker may be connected to replace the internal speaker and provide better sound quality. Dial-up line RJ11 terminal jack; connects to a 2-wire dial-up line wall jack.
If the modem’s parallel port is always connected to a laser printer for fax printing, a computer/terminal can connect to the modem’s AUX RS232 serial port for issuing AT commands and reception of responses. This is good for configuration and monitoring operation without disconnecting the laser printer. This AUX RS232 serial port is intended only for AT command and response’s transmission; it is not intended for DTE data transmission. Auto speed detection is not supported on this AUX RS232 port.

Chapter 4 MODEM OPERATION Parallel or Serial Port Operation The 2864 models provide both a parallel port and a serial port for DTE connection, but only one out of three connection modes may be active at any time. The available modes are: • SP: Serial port mode; • PRP: Printer parallel port mode; • PCP: PC parallel port mode. Only when a port is actively driven and/or terminated externally may that port be active, i.e., the connected device must be turned on and must drive the port.
PC Parallel Port Operation If the modem's parallel port is connected to a PC's parallel port, the PC can communicate with the modem through the parallel port link. Be sure that your PC has a bidirectional parallel port. The modem's parallel port will not work with the old unidirectional parallel port. You need not have EPP nor ECP capability on your parallel port. Using the parallel port, the PC sends and receives 8 data bits at a time to and from the modem.
ZyXEL Parallel Port Adapter ZyXEL is developing a special parallel port adapter that will make parallel port transfers much faster between a PC and the Elite 2864. The speed limitation in this case will be determined by how fast and how efficient the PC software program can handle the data. The operation instructions for this special parallel port adapter are included in the adapter manual. Check ZyXEL's announcements for availability, which is expected to be within a few months of the 2864's introduction.
Firmware Update/Upgrade The 2864 series modem uses 4Mbit flash EPROM(s). The firmware in flash EPROM can be updated by uploading a file from the locally connected DTE. There is no need to open the modem case or use a programming device. The firmware is distributed in a file with the following naming conventions: E2864md.vvv where • m is the model with value I, L, or nothing. • d is the D channel protocol for ISDN. Check the 2864I user's manual for applicable values. • vvv is the version number.
For the Supreme models, pressing the MENU key (the UP arrow key) while turning on the modem will have the modem execute the kernel program. You can also use the ATUPA command to upload the firmware file. In this case you can simply dump the firmware file to modem after typing the ATUPA command. DRAM Upgrade Open the modem's upper case. You will find four 26-pin sockets on the modem circuit board for 24-pin (26-pin size chip with 2 pins absent) 300 mil., SOJ package DRAM chips.
On the internal card model, short the TS2 jumper with a plug, then power up the computer. The modem will be reset and will run a self-test. Printable characters will be shown on the computer screen. The TS1 LED should be continuously ON. If the LED flashes, the number of flashes indicates the error number corresponding to the error message listed at the beginning of chapter 18. This hardware reset procedure will reset the supervisor password back to the default ZyXEL. But if you set S35.
Chapter 5 Fig. 5.1 2864 QUICK START Fig. 5.2 This chapter explains how to dial and answer using a modem. If you use this modem with a PC, you probably don't need to worry about modem settings. The factory default should be just right for you. Connect the modem according to the instructions in chapter 3, install the communication software, make the modem dial as instructed in this chapter, and you're all set. Furthermore, an introduction to the panel operation of the Supreme 2864L is presented.
The cursor is blinking above one of these on-screen buttons - a dark rectangle which may be moved using the keys next to the display. The modem also displays the current status and settings in the idle screen: Information Example V34 (V.34) 28800 (bps) V42 (implied by V.42bis) V42b (V.42bis) DL (Dial-up line) AS (asynchronous) 115200 (bps) Link Option Link Speed Error Control Data Compression Line Type Data Format DTE Speed Panel Operation Use the four arrow keys to manipulate the menu tree.
LED status screen has five status indicators - DCD, DSR, CTS, RTS, and SQ. These status indicators are identical to the LED indicators of the non-LCD modems. Values in one of the other screen displays may give much more detailed information than some of these status indicators; e.g., a data state screen means DCD is on, and an idle screen means DCD is off; SQ is better explained by the S/N ratio reading and the other impairment readings of data screen 2.
Dial Memory The first menu of the dialing directory is DIAL MEMORY. Pressing the ENTER key will cause the following screen to appear: #01: 1234567 << >> SELECT MEMORY Dial out the number Equivalent AT Commands AT&Z? View all stored phone numbers. ATDSn n = 0 - 49; dial stored number. The first stored number shown on the menu is the default dial number which can be selected from the DEFAULT DIAL menu.
ENTER. The blinking cursor will change into an underscore and will move to the next position on the right side of the colon(:). SELECT MEMORY will change to SELECT DIGIT. Press the left and right arrow keys to scroll through the valid digits and characters for dialing. Pressing ENTER will confirm the selected digit and cause the cursor to move to the next position. Repeat the above procedure to finish entering the number, then press ENTER again to save the entry in the EEPROM.
When you want to switch from modem to voice communication, simply lift up the handsets of both sides and press the ENTER key while the blinking cursor is on the H or Hang Up. The LCD display will show DISCONNECTING ? to ask for a confirmation. Press ENTER again and the modem will change from data to voice communication. When both sides wish to return to data communication, one side should press O while the other side presses A (as explained previously).
Dialing Messages Dialing will cause the following screen to be displayed on the LCD: DIALING...................... 1234567 The dialed phone number will be displayed on the second line of the 20×2 LCD screen. If the number exceeds 20 digits, only the first 20 digits/characters will be displayed. If the modem's DIAL-UP LINE jack is not plugged in or not connected, the LCD screen will display the following: NO DIAL TONE.......... 1234567 then the modem will go back to the IDLE STATUS screen.
If a connection has been made, the LCD will display the actual connected status. These are data state screens: V.34 28800 V42b DL H>> 55820 51324 AS << SN= 30.9 RX=-25.1 >> PJ= 0.4 FO=-0.
On-line Status Screen 4 Status FRN ( Fast Rate reNegotiation) Granted FRN Requested Blocks Retransmitted FCS (Frame Check Sum) Errors Display 0 0 0 0 Unit Pressing the left or right arrow key in any one of the ON-LINE STATUS screens will cause the LCD to scroll through the four screens. We will discuss the ON-LINE STATUS screens 2, 3, and 4 in more detail in chapter 18.

Chapter 6 MODEM PARAMETER SETTINGS This chapter explains how to view and set various major modem parameters using the Supreme 2864L CONFIGURATION menu tree. The non-LCD model users can also consult this menu tree for available parameter options, but must use the equivalent AT command to set the parameter. The various levels of the CONFIGURATION menu tree are defined here as: CONFIGURATION menu submenus parameter menus parameter selection whereby the CONFIGURATION menu is the root of this menu tree.
Parameter Selection Press the left or right arrow key to view and scroll the available parameters. Only the parameters currently in effect have the equal sign (=) before their respective selections, otherwise a colon (:) appears, meaning that this parameter choice is a selectable option. By pressing MENU to quit the viewing, the screen will return to the parameter menu and the parameter will remain unchanged. Press ENTER to avtivate the selected parameter.
TERMINAL OPTIONS DATA FORMAT + ASYNC AT&M0 SYNC DATA AT&M1 DIRECT AT&M2 SYNC AT&M3 Operates as an asynchronous modem with data buffering, may work with data compression and/or error control. Fixed DTE speed with flow control. (Default) The modem accepts asynchronous commands, but changes to synchronous operation in data mode and exchanges data synchronously with a remote modem. Direct asynchronous mode without data buffering. DTE speed equals link speed. The modem accepts synchronous commands (V.
DTE RATE + FIXED AT&B1 FOLLOWS LINK RATE Note: AT&B0 Modem serial port speed is always fixed, no matter what link rate (modem speed) is connected. If S44.6=1 and a non-ARQ connection is made, DTE rate follows link rate as if &B0 were set. (Default) Modem serial port speed is set in accordance with the link rate. If S44.6=1, the DTE speed is fixed at 38400 bps when the link speed is above 9600, at 9600 when the link speed is 7200, and at link speed when it is below 7200.
RTS OPTIONS + IGNORED AT&R1 CTS TRACKS RTS Note: AT&R0 The modem assumes that RTS is always ON and ignores the serial port signals. (Default) Delay before CTS responds to RTS's change.

Chapter 7 PROFILES The 2864 series modems let you save up to 4 sets of configurations which are called profiles. You can save each entire modem configuration in the non-volatile EEPROM memory for later use as default settings, or you can use it as the power-on default. Use the SAVE TO configuration submenu to save the current configuration to a profile, or use the &Wn command to save to profile n. AT&Wn Please note the different use of profile numbers in the AT&Vn and AT&Wn commands.

Resets the modem and loads user profile 2. Resets the modem and loads user profile 3. Resets the modem and loads the factory default profile. Selecting profile n will reset the modem and load user profile n. Profile n is also set as the power-on profile. Saving to Profile You can save your current settings to one of the four user profiles.
Note that only profile 0 can be protected. Setting S35 bit 6 in profile 0 will also protect the supervisor password. If this bit is set, the supervisor password cannot be reset to the default ZyXEL by a modem hardware reset (see chapter 18). Memorize your password well before setting this bit. Resetting Profiles After you have changed the user profile settings, you can reset all four user profiles to factory preset values if you wish.
Chapter 8 STATUS REGISTERS S-registers (status registers) contain values that determine and reflect how your modem operates and executes commands. You can read their values and change them, either using terminal commands or the modem's panel controls with the same results. Every user profile corresponds to a set of S-register values, but when we mention S-registers, we are referring to the ones that correspond to the active profile.
For example, if you want to set S38 bit 3 to 1 for a specific application, you may either use ATS38.3=1 (simple) or use the following method (difficult): Note: The values used in the example below differ from the actual values in the S-register and are used for demonstration purposes only. • Read the value from S38 using ATS38?. • Convert it to its binary value, using the following weight table.
S-Register Descriptions The descriptions for each S-register follow. In most bit-mapped S-registers, the default bit value is 0 (which is the normal situation) and only the non-default situation is described. Some reserved bits are for factory use and the user should not change them. The Standard AT-Registers Register Default S0 0 Min. 0 Max.
Register Default S7 60 Min. 0 Max. 255 S8 2 0 255 S9 6 0 255 S10 7 0 255 S11 70 0 255 Note: Description Sets the number of seconds the modem will wait for a carrier. If the modem does not detect a carrier within this time limit, it hangs up and returns the NO CARRIER result code. Sets the duration of delay generated by the comma (,) dial modifier. Also sets the pause between command re-execution for the repeat (>) command.

Chapter 9 AT COMMAND SET SUMMARY An AT command is a command issued by the computer/terminal to the modem through the asynchronous computer-modem interface in asynchronous data format. AT commands control the modem's behavior and actions. To send an AT command from a computer to the modem, you must be running a communication software and the modem must be in command state. An AT command prefix (ATtention) precedes each command line, except in the case of A/, A>, and +++. A/ re-executes the last command once.
R ! , ; @ + Originate a call in answer mode; must be entered as the last digit. Hook flash. (Call transfer; see also S56) Pause for a time designated by S8. Return to command state after dialing. Wait for a 5-second silence before proceeding, otherwise return NO ANSWER. DL Dials the last-dialed number. DSn Dials the number stored in EEPROM at location n(0-49). S44.3=1 enables cyclic dialing. If the first dial is not successful, the modem will cycle dial through the first ten numbers stored in memory.
Q2 The modem returns a result code but quiet after answering on a RING. (See also S42b2) Sr=n Sets S-register r to value n; n must be a decimal number between 0 and 255. Sr? Displays value stored in S-register r. Sr.b=n Sets bit b of S-register r to value n. (n is a binary digit: 0 or 1) Sr.b? Display value of bit b of S-register r. + + T Tone dial. (Default) V0 Displays the result code in numeric form. (See also S35b7 and the result code table of ATXn.

Chapter 10 ERROR CONTROL AND DATA COMPRESSION Error Control Error control keeps the modem data link error-free by detecting and retransmitting erroneous data. ZyXEL modems support both MNP and V.42 error control protocols. The MNP protocol was an industry de facto standard developed and licensed by Microcom, Inc. ZyXEL modems support level 4 and 3 error control protocols, commonly denoted as MNP4 and MNP3. V.
3) Automatic Re-transmission Request (ARQ) Error Correction Once a data block is received error-free, the receiving modem will acknowledge this block immediately. The sending modem receives the acknowledgement and will check if any block(s) is(are) not acknowledged. Let us assume 18 blocks were transferred and the first 14 blocks were acknowledged. If no acknowledgement for block 15 is received in a given time, this block must have been damaged. Acknowledgements of blocks 16 through 18 are ignored.
Run-length Encoding Run-length encoding is applied in an attempt to avoid sending long sequences of repeated characters (data). When three or more repeated characters appear in succession, only the first three tokens (representing the compressed format of that character) and a repetition count will be sent. Adaptive Frequency Encoding Adaptive frequency encoding is applied after removing repeated characters (data).
Bidirectional Compression Processing data compression consumes a lot of the modem controller CPU's computation power. Though data compression protocols of V.42bis and MNP5 are bidirectional, most modems slow down when doing bidirectional file transfers because of limited processing power. ZyXEL 2864 series modems use a powerful 16-bit processor that does not slow down during bidirectional file transfers.
Hints for High-speed Operation The communication software tends to lose incoming serial data when it is doing block disk data transfers, because the hard disk interrupt priority level is usually higher than that of the serial port interrupt in the computer. The communication software can do a hardware flow control during disk data transfer to prevent this. Enabling a disk cacheing software such as SMARTDRV will help. Please refer to chapter 21 for more information on high-speed PC-modem communication.

Chapter 11 SYNCHRONOUS OPERATION This chapter introduces you to the use of the 2864 series modem for synchronous operation. Use the modem as a synchronous modem when it is connected to a synchronous computer or terminal. Be sure that the remote modem and system are also set to synchronous. Synchronous operation applies to all of the non-FSK modes the modem is supplied with. The serial port models support synchronous mode operation.
Half-Duplex Operation For a half-duplex modem, the carrier only exists in one direction at any specific time. The carrier, the local CTS signal, and the remote CD signal will follow the RTS signal in a certain manner. Some communication software packages written for half-duplex modems rely on these RTS, CTS and CD signals. For a full-duplex modem, carriers are always present in both directions. In order for it to simulate a half-duplex modem, the V.
4) Dial from the panel. This is available only with an a LCD model’s LCD panel. Set the modem to synchronous mode, then select DIAL MEMORY or DIAL NUMBER to dial out the number you want. After the modem is connected, the modem will enter synchronous operation. 5) Manual dial. Set the modem to synchronous mode (&M1 or &M3), then dial a number from a telephone set. When you hear the answer tone, type ATD (if &M1 is set) or press O in the IDLE SCREEN menu from the panel.
Setting up a ZyXEL Modem with the AS-400 This is a typical application where the user will use both the synchronous feature of the modem and the V.25bis option. Although we are using the IBM AS-400 computer as an example, other mid-range systems and mainframes should be able to use the same strings. Please note that some systems may require other settings depending on the nature of the system or the application that you are running. You can consult our Technical Support Department if help is needed.
4) To save the settings to a profile, press MENU once, and press the right arrow key until you see SAVE TO. Press ENTER and then the right arrow key to choose the profile you would like to save to; then press ENTER again to select it. 5) To activate these settings as your power-on default, you need to reset from this profile at least once. To do it from where we left off in 4), press the right arrow key and stop at the RESET submenu.

Chapter 12 LEASED-LINE OPERATION A leased line is a permanent telephone line connection between two fixed points. It can be dedicated copper wires or a leased telephone circuit from the telephone company. The 2864L model supports 4-wire and 2-wire leased lines. 4-wire leased lines use one pair of wires to transmit data and a second pair to receive. 2-wire leased lines transmit and receive on the same pair of wires.
Power Level The modem's leased-line mode transmission power level can be adjusted from 0 dBm to -27 dBm in 1 dBm increments. If a dial-up model is used for 2-wire leasedline connection, the transmission power is limited to -9dBm for the Omni 288P and to -3dBm for the Omni 288S. LLINE TX POWER AT*P0 … AT*P15 The default is -9 dBm. The adjustable range is from 0 to -15 dBm, effective in leased-line operation only. If bit 3 of S35 is set, this range will change to -12 to -27 dBm.
Auto-handshake If you want handshaking to occur automatically upon power-up, you have to save the leased-line configuration to the power-on profile. How to designate a profile to be a power-on profile is described in chapter 7. Please remember to set the handshake mode before you save the configuration. Be sure that one modem is set to originate mode and the other to answer mode. + ORIGINATE AT*M0 ANSWER AT*M1 When operating over a leased line, modem will handshake in originate mode.
It will try these two alternatives indefinitely. If the dial backup attempt succeeds, the value of S-register S34 determines the interval of the dial backup connection before going back to check the leased line. ATS34=0 ATS34=n; (1 ≤ n ≤ 255; default: 30) The dial backup line continues to be used indefinitely. Reattempts leased line after n minutes. If the leased line has still not been recovered, the modem will continue to use the dial backup line. A semi-auto dial backup is selected if S44.2=1.
Chapter 13 SPECIAL FUNCTIONS This chapter describes the special features of the 2864 series modems including their functions and uses. Security Function The 2864 series provides a security function, that (when enabled) prevents an unauthorized user from making a connection. Two types of security functions are provided. Type 1 security is used when the remote modem is also a ZyXEL modem; type 2 security is used when the remote modem is any other brand of modem.
Password: (Enter supervisor password) ******** Password: (Enter new supervisor password) ******** Verify: (Enter the new supervisor password again) ******** OK The command AT*Hn will modify the nth user password. You will be prompted to enter the supervisor password first and then be prompted to enter the nth user password. The command AT*V will list the 50 user passwords and the supervisor password on the screen for viewing. Again, you will be prompted to enter the supervisor password first.
Local profile modification is done by loading this profile as the active settings and then modifying and saving the active settings back to the profile. Then the connection is reestablished and the profile is transmitted to the remote modem. Reading a remote profile b into a local profile a is done by the command: AT*Rab whereby a=0-3 b=0-3 b=4 b=5 Local user profile number. Remote user profile number. Remote active configuration. Remote factory default. Return the modems to on-line status again.
mote modem in one action. It is particularly useful when there are many remote modems and a set of standard configurations is available so you can store them into user profiles. You just need to configure the remote modem into one of the standard configurations by activating the remote configuration once. Caller Number Delivery(CND) Caller Number Delivery (CND), commonly called Caller ID, is a new kind of phone service that may be offered by your local phone company.
CALLER NUMBER: 7135551414 or CALLER NAME: Jack Smith RING In the multiple message format, if the caller's number and name are available, the ring message will be: RING TIME: MM-DD hh:mm CALLER NUMBER: CALLER NAME: RING Following is an example: RING TIME: 04-28 12:30 CALLER NUMBER: 7135551414 CALLER NAME: Jack Smith RING If the caller number and name are not available, the ring message will be: RING TIME: 04-28 12:30 REASON FOR NO NUMBER: OUT_OF_AREA REASON FOR NO NAME: PRIVACY RING
A simple use of this feature is that you can have three numbers on the same line and you can list the three numbers for voice, data, and fax, respectively. You can then have your fax machine answer only the ring corresponding to the fax number and have your modem answer only the ring corresponding to the data number. The voice call will not be answered by either fax machine or data modem and it will only be answered when someone picks up the phone.
telephone line for occasional fax or data calls; however, fax/data calls do come in from time to time. If a user lets the fax/data software application answer calls, voice calls will be missed; on the other hand, if a human being or an answering machine answers calls, fax or data calls may either be missed or the person who answers a call has to go through some trouble to get this call connected to the proper application. Either way is not desirable.
The EDR settings are defined in S-register S51. S51 Bit-mapped register, default: 0: Code Bits (7,6) (5,4) (3,2) (1,0) Bin. 00 01 10 11 00 01 10 110 00 01 10 11 00 01 10 11 Dec. 0 64 128 192 0 16 32 48 0 4 8 12 0 1 2 3 Description Disables data CNG tone detection. Reports RING for data CNG tone. Reports RING 1 for data CNG tone. Reports RING 3 for data CNG tone. Disables Fax-CNG tone detection. (Default) Reports RING for fax CNG tone. Reports RING 1 for fax CNG tone. Reports RING 2 for fax CNG tone..
Application Example In the previous example, an answering machine was installed with a ZyXEL modem. If we use ZFAX as our fax receiving application and we don't want it to answer the call unless it is a fax call, the way to set it up would be: 1) Set ZFAX to answer on 2 rings. 2) Set S51.0=1 to enable EDR and report RING twice. The modem will not report a normal RING and ZFAX will not answer a call unless an EDR RING is reported. 3) Set S51.4=1 to enable fax CNG tone detection. It is reported as RING.

Chapter 14 CELLULAR MODE OPERATION The ZyXEL 2864 series models are equipped with a special communication mode cellular mode - which enables the modem to perform reliable high speed data transmissions over cellular phone links. Although most ZyXEL modems can provide the cellular mode, the U-1496P portable modem is specially designed for mobile use. It is portable in size and capable of using DC12V car battery power. An optional power cable that plugs into the cigarette lighter can be used with the modem.
A cellular phone may be instructed to change its transmission power depending on its distance from the cell site station. The radio link will be interrupted for about 0.2 second. An effect similar to cell hand-off will occur. A particularly difficult cellular impairment for data communication is called multipath fading. A cellular phone receives the cell site station's radio signal through many indirectly reflected paths.
ZyXEL ZyCellular Modes In addition to normal modem, fax, and voice operation modes, the following cellular modes are offered in 2864 series modems: Mode Speed MULTI-AUTO CELL 14400 CELL 12000 CELL 9600 CELL 7200 CELL 4800T V.34/ZyX modes/V.32bis/V.32/V.22bis/G3 FAX/Cellular Modes 14400/12000/9600/7200/4800 12000/9600/7200/4800 9600/7200/4800 7200/4800 4800 CELL 14400 will connect with another modem using cellular mode at a speed of up to 14400 bps. It will also connect with another V.32bis/V.32 modem.
S49b7 tells the modem where it is installed. If S49.7=0, the modem is installed in an office connected to a normal telephone line; if S49.7=1, it means the modem is a mobile unit connected to a cellular phone. When a ZyCellular modem calls or answers another modem, it will indicate its cellular capability and whether it is using a cellular phone.
Fig. 14.1 is an example of a mobile phone that has a handset cradle and a separate transceiver and handset. Fig. 14.2 is an example of a mobile phone that has a separate transceiver and handset.
Fig. 14.3 is an example of a one-piece hand-held mobile phone. Fig. 14.3: Example 3 - U-1496P with a hand-held phone Some newer cellular models, particularly the hand-held ones, have an audio jack that can connect the cellular phone's audio input/output to an outside headphonemicrophone set. A simple adapter cable can be used to connect the RJ11 modem's 2-wire interface to this cellular phone's audio jack.
Chapter 15 FAX OPERATION The 2864 series universal modems support the Group 3 sending and receiving facsimile function. For normal fax operation you must connect the modem to a computer, usually a PC. The computer is the input/output device for the fax function. The interface between the modem and the computer is the normal RS-232 serial connection or the ZyXEL parallel port interface. The modem uses the same interface for both data and fax applications.
Fax Command Sets The 2864 series universal modems support four command sets for the fax function, the Class 1 command set, the TIA PN-2388 Class 2 command set, the TIA 592 Class 2.0 command set, and the ZyXEL Extended Fax AT command set. The Class 1 protocol uses the modem to transmit the fax data only. The complete organizational overhead for this protocol is handled by the connected computer. The available Class 1 commands are listed first in this chapter.

The modem accepts the extended fax AT commands to set the modem mode and fax parameters. Besides the extended fax AT commands, the modem accepts all the other AT commands described in chapter 9. For instance, you can use ATD to make a fax call, or ATA to answer an incoming fax call. When using the extended Fax AT commands, you need to send the command AT+FCLASS=6 first.

The following flow control signaling is used while receiving a fax: CTS is not used when receiving a fax. RTS is used to inform the modem that the computer cannot accept data at this moment. The modem will not pass received data to the DTE if RTS is turned off. When finished receiving the fax message, the modem will turn off CD, then send a status report result code to the DTE.
2) Change one of the connection messages in the list to CONNECT FAX. 3) Set the external mail string to ZyXEL and give it an error level. 4) In your BBS batch file, if the error level matches the external mail, execute rcvfax 2 /p:comport [/w:workpath]. This setting will enable the BBS to receive a fax and store it automatically.
Use the serial port to enter the command: AT+FCLASS=Z The modem will enter into direct fax reception and print mode. Youalso need to set the S0 register to a finite number to enable auto-answering. To further detail operation in Class Z mode, the special command AT+FZF has been implemented to define the fax reception mode under Class Z operation. • +FZF=n ZyXEL fax reception mode selection for parallel port printing, auto-data and DRAM storage. n=0 n=1 Fax to printer, hangs up if data.
The modem supports laser printers compatible with HP Laserjet-II printers or laser printers supporting the HP PCLII programming command language. This includes essentially all HP-compatible laser printers on the market. Different laser printers may have different print speeds. The fax receiving speed depends on the fax connection speed. For current standards, the connection speed is from 2400 bps up to 14400 bps. For the upcoming V.34 fax standard, the speed may run up to 28800 bps.
Stand-alone FAX Reception and Storing With the DRAM option installed, you can have the modem receive faxes and store them in the DRAM. To work in this mode, you need to use the AT+FCLASS=Z command to set the modem to work in the Class Z mode. Also, you need to use the +FZF=n command to set the modem to work in one of the following modes: n=2 n=3 n=4 n=5 Fax to DRAM and printer, hangs up if data. The modem always answers.
You can use a computer with your existing fax software package to retrieve fax pages stored in DRAM. Use either the parallel port or the serial port to connect your computer to the modem and run your favorite fax program. When the fax program sets the modem to fax Class 2 or Class 2.0 mode, the modem will emulate fax calls coming in, have the fax program receive the fax calls, and then dump all stored fax pages to the fax program.
Chapter 16 ADVANCED VOICE CAPABILITY Voice capability stands for the modem's ability to digitize incoming voice messages, which the computer stores and forwards. It also means that the modem can playback the recorded digitized voice either off-line for local message listening or online for a message announcement. For interactive voice applications, DTMF tone detection capability is important so that a computer can react according to the remote caller's touch tone input.
of data. It is the recommended 3-bit ADPCM scheme. It will automatically recover from data errors when playing without producing a noisy voice signal. The modem also supports simultaneous DTMF (Dual Tone Multiple Frequency) tone detection, thus enabling the use of the keypad of a tone-dialing push-button telephone set to control, instruct, or answer the modem.
In ZyXEL voice mode, three states exist that roughly correspond to the flow direction of the digitized voice data; the Voice Command State (no data transfer other than event reports), the Voice Transmission State (digitized voice data transfer from the DTE to the DCE), and the Voice Receival State (digitized voice data transfer from the DCE to the DTE). Note that the voice data DTE/DCE transfer is half-duplex. The DCE may issue event detection reports at any time, regardless of the DCE state.
Voice Data State The DCE is in Voice Data State when the DCE is operating in voice mode and is communicating with a remote station or with one or more local devices which are capable of translating analog signals to voice (e.g., speaker) or translating voice to analog signals (e.g., microphone). The DTE transfers data to the DCE for transmission to the remote station, and the DCE transfers data to the DTE after reception from the remote station.
(2) does not expect to receive digitized data from the DTE, perform conversion, or transmit the analog signal to the remote station or to one or more local devices. The ZyXEL 2864 series modems provide three ways to leave the Voice Receival State: (1) A shielded code is received from the DTE. (2) Characters other than , or a shielded code is received from the DTE. (3) A DTE/DCE inactivity timer time-out occurs.

This may indicate a hang-up or other events depending on the implementation of the central office. Ringback. BUSY. If the DCE continues to detect a BUSY signal, it may report this event repeatedly. The delay between reports is 4.0 seconds. DIAL TONE. If the DCE continues to detect a DIAL TONE, the DCE may report this event repeatedly. The time interval between reports is 4.0 seconds.
(0x3) Ends Transmission Data State: The DTE sends this code to signify the end of the voice data from the DTE and cause the DCE to return to the Voice Command State. The DCE will complete the transmission of the contents of its buffer before switching to the Voice Command State and returning the OK result code.
whereby represents a two-letter command syntax. A value string consists of values separated by commas or semicolons. The first two command forms are for read actions, the last two are for write actions. A command line may have both action types or be just a read or write type only. Response Syntax For each command line received, the modem issues a response to each command in the command line followed by a final response.
DCE reports this result code when the DCE has determined upon detection of an answer-tone that the remote station is a data modem. The DCE may also issue this result code when the DCE has assumed that the remote station has gone off-hook by actions associated with the +VRA and the +VRN commands. The DCE issues the NO ANSWER result code when the DCE has continuously detected ringback for the amount of time specified in S-register S7. • ATH (with + FCLASS=8) This command causes the DCE to hang up the phone.
• AT+FCLASS=? The DCE returns permitted modes. The response is (with S57.4=1): 0,1,2,2.0,6,8,Z OK • AT+VLH=? This enables the DTE to inquire the hook status of the connected local phone. The DCE will return 0 for on-hook and 1 for off-hook status. • AT+VNH= The DCE enables or disables automatic hang-up to a varying degree for data and fax modes.
• AT+FLO? The DCE returns the current flow control setting, followed by the OK result code. • AT+FLO=? The DCE returns permitted flow control methods.
(2) The DTE sends a shielded code. (3) A DTE/DCE Inactivity Timer time-out occurs. Upon termination of the voice receival state, the DCE will append a character pair, followed by the OK result code. The DCE then returns to the Voice Command State. The Inactivity Timer is in effect while the receival operation is in progress.
• AT+VTX This command causes the DCE to start the voice transmission process. The DCE begins the Voice Transmission Mode by returning the CONNECT result code to the DTE. After this report, the DCE accepts shielded voice data from the DTE. The DTE shall send the data in the format previously selected by the +VSM command and use the flow control method selected by the +FLO command. There are two ways to leave the Voice Transmission State: (1) (2) The DTE sends a shielded code.
The DCE returns the result code OK if the DCE accepts this command, or it returns the result code ERROR if the parameter is out of range. • AT+VGT? The DCE returns the current transmission gain, followed by the OK result code. • AT+VGT=? The DCE returns permitted values for the transmission gain. The response is: 56-200 OK • AT+VIT= This command sets the inactive time-out value for the DTE/DCE Inactivity Timer. The default value is 7 seconds. Acceptable values are 0 to 255 with a unit of 0.
The DCE returns the VCON result code (returns OK if S48.5=1) if the DCE accepts this command, or it returns the ERROR result code if the value is not permitted. • AT+VLS? The DCE will return the current I/O device followed by the OK result code. • AT+VLS=? The DCE will return permitted I/O devices. The response is: 0,1,2,8,16 OK • AT+VRA= The DCE only uses this command in a call origination transaction.
The DCE returns the OK result code if the DCE accepts this command, or it returns the ERROR result code if the value is out of range. • AT+VRN? The DCE returns the current Ringback Never Appeared Timer interval value followed by the OK result code. • AT+VRN=? The DCE will return the permitted interval for the Ringback Never Appeared Timer.
• AT+VSM= This command causes the DCE to select a compression method as follows: 2 3 30 4 Compression Method Description ZyXEL 2-bit ADPCM (default) ZyXEL 3-bit ADPCM ZyXEL new 3-bit ADPCM ZyXEL 4-bit ADPCM The DCE returns the OK result code if the DCE accepts this command, or it returns the ERROR result code if the value is out of range.
• AT+VTD? The DCE returns the current beep duration and pause interval setting followed by the OK result code. • AT+VTD=? The DCE returns the permitted values for the beep duration and pause interval. The response is: (0-255), (0-255) OK • AT+VDD=, This command causes the DCE to set the DTMF detection threshold and the required period of continuous DTMF tone detection before the DCE can report a DTMF event.
The DCE returns the OK result code if the DCE accepts this command, or it returns the ERROR result code if the value is out of range. • AT+VSY? The DCE returns the current resync timer value, followed by the OK result code. • AT+VSY=? The DCE returns the permitted interval of the resync timer. The response is: 0-255 OK Note: AT+VSY is not defined in the IS-101. The IS-101 did define that the DTE can send a code to have the DCE reset its decompressor and concatenate following voice data.

Connecting a Telephone Set to the Modem's PHONE Jack A normal telephone set can be connected to the 2864 modem's PHONE jack and be used for recording and playback. A telephone set needs DC voltage and a current supply to work. This DC voltage is normally supplied through the phone line from the telephone company or a PABX. The ZyXEL 2864 series modems are designed to provide DC voltage and current to the telephone set connected to the PHONE jack.

Chapter 17 NETWORK MANAGEMENT CAPABILITY When there are several modems installed at different places forming a modem network, it is desirable to monitor and control all of the modems and modem links from a central location. When there are hundreds of modems installed at one central location, it is also desirable to control and monitor all of the modems from the desk of a computer workstation. We call this a Modem Network Management System (MNMS).
NMS Capable Models All ZyXEL rack models except the RE and RE+ models are NMS capable, but only the model with the N suffix has the secondary channel capability. A secondary channel is necessary for remote control and hierarchical control. For a large central site local control, the secondary channel is not needed. Also, for dial-up use, like a couple of racks for a multi-line BBS, remote control and hence a secondary channel is usually not needed.
Chapter 18 DIAGNOSTICS The 2864 series modems provide several diagnostic capabilities: • Power-on Self-Test • Analog Loopback Test • Analog Loopback with Self-Test • Local Digital Loopback Test • Remote Digital Loopback Test • Remote Digital Loopback with Self-Test • Line Condition Status Display • Re-transmission Indicator • Throughput Display • Link Status Report • Modem Reset All these tests apply to the asynchronous or synchronous, error controlled or nonerror controlled, data compression enabled or dis

ing the test. This test can only be initiated while the modem is off-line. If the parallel port DTE interface is used, this test will test the parallel port interface. Modem Transmitter DTE A Phone Line B Receiver A: RS232 Interface ALB B: Line (Jack) Interface Analog Loopback with Self-test (AT&T8) This test generates data from the modem itself instead of input data from the RS-232 interface. The data will go through the same path as it would be with the Analog Loopback Test.
Level field of the LCD screen will indicate LDL. The Elite model’s TST LED indicator will be ON. This test can be initiated by the local modem when the modems are on-line. Remote Modem Local Modem Transmitter A Transmitter ~ ~ ~ ~ B A B Receiver DTE Receiver LDL Remote Digital Loopback Test (AT&T6) This test will request the remote modem to do a digital loopback. During testing, the local modem will send a remote digital loopback request to the remote modem according to V.54.
cal modem both provide V.54 Remote Digital Loopback capability. The Control Level field of the LCD screen of the initiating modem will indicate RLBST, and that of the accepting modem will indicate LDL. This test can be initiated by either modem when the modems are on-line. Local Modem Remote Modem Transmitter DTE A C B ~ ~ ~ ~ Transmitter B Receiver A Receiver LDL RLBST Line Condition Status Display The screen displays of this section only apply to the LCD models.
Received Signal Power Level (RX) This reading is expressed in 0.1 dBm resolution. The modem-measured receiving signal power is generally within 1-2 dBm of the actual value with relative accuracy. The receiver sensitivity specification for the 2864 is -43 dBm. Strong signal power could cause signal saturation in the channel and degrade the data validity. To avoid this situation, decrease the transmission power of the remote modem.
ON-LINE SCREEN 4 also has four counters recording the modem's actions and reactions. << FG= 0 FR= 0 BR= 0 FE = 0 FRN (Fast Rate Negotitation) Granted (FG) The count of the granting of the remote modem's change rate (FRN) requests. Each request is an indicator of a changed receiving condition. FRN Request (FR) The count of the local modem's requests to change the rate. Block Retransmitted (BR) The count of the blocks retransmitted (bad receiving on the remote modem).
This Link Status Report is very helpful in finding out the link condition and what is wrong with the link, if anything. Following are the explanations for each item and the terminology used in this report. Chars Data characters transmitted between the DTE (computer/terminal) and the modem. Octets Data bytes transmitted between the modems, handled by error control protocol, may be compressed data. Data compression efficiency may be seen from the ratio of chars count to octets count.
Retrains Requested Number of times the local modem has requested a retrain. Each request is an indicator of bad receiving conditions. Retrains Granted Number of times retrains requested by the remote modem were granted. Link Duration Connection time in minutes. T401 Timeouts and T402 Timeouts These are for the manufacturer checking link layer operation. T401 and T402 are timers used in MNP4 or V.42. T402 will count when the modem is connected in the idle state with no data to transmit or receive.
Throughput Display If the modem is operated in asynchronous operation, we can tell the line quality from the Throughput Display. If the speed displayed is slower than usual or what you expected, check the S/N reading. If it is good, check the configuration of the modem and the computer's serial port setting, particularly the flow control setting, or even the configuration of the remote site.
Chapter 19 GENERAL HINTS AND TIPS Activating Saved Settings upon Turning-on Use the command ATWn to save a set of parameters into one of the available profiles. Make these settings your current settings by resetting the modem from the profile using the command ATZn. The active profile will be used at the next poweron. Refer to chapter 7 for further details. Avoiding Low Throughput and Loss of Data Some computers serve and poll their serial port so slowly that data is lost.
ING message with the RING message which the modems return when they detect an incoming call. These programs usually interrupt the connection and try to receive the non-existing call. Disable the RINGING message with ATS42.6=1. Calling from an Extension / Blind Dial If your modem is connected to a large inhouse telephone system, it may be necessary to disable the modem's dial tone detection since many systems do not provide a standard dial tone. This is done by setting ATS41.4=1.
Chapter 20 THE FIRST CONNECTION Telecommunication using computers and modems is a simple task. You need only observe a few - important - parameters. This example shows you how to log into a BBS using the terminal program which is included with Microsoft Windows 3.x. As a Windows component, this simple terminal program has been widely distributed and offers the basic features of a telecommunications package. Many other programs are available which offer many more options.
4) From the menu Settings, choose Modem Commands and in the dialog, choose the parameter set Hayes. 5) Go to the dialog Settings - Terminal Emulation and choose DEC VT-100 (ANSI). 6) In the dialog Settings - Terminal Preferences, activate Line Wrap from the Terminal Mode options. Use the 80 characters per line display. Do not activate the CR to CR/LF conversion. The option Local Echo should be inactive as well. 7) From the menu Settings, enter the phone number you wish to call later.
Chapter 21 ZyXEL MODEMS AND A PC All of the modems of the 2864 series may be used with a PC. If you install the internal PC card model, you don't need a serial cable. The modem's standard profiles should be just fine with most applications. If you are connecting to the modem’s parallel port, make sure that you have a bidirectional PC parallel port and use a 25-wire cable to make the connection.
For high speed serial connections at 230.4Kbps or 460.8Kbps, use a low-capacitance cable. Also, keep the cable as short as possible. Parallel Cable Use a 25-wire cable with a male connector at one end and a female connector at the other end to connect the PC’s parallel port to the modem’s parallel port. Keep this cable as short as possible. This cable may also be used to make the 25-pin serial connection. Using the Windows 3.1 Terminal Program You will not be able to use a transfer rate of more than 19.
WINDOWS folder during the installation of Windows. Increasing the serial port priority in Windows may degrade the performance of other programs. While data is written from the transfer-buffer to your hard-disk, characters may be lost at the serial port. This is due to the fact that disk-access interrupts have a higher priority than serial port interrupts. If you are running at a high serial speed, e.g. 230.4Kbps or 460.

Chapter 22 ZyXEL MODEMS AND UNIX Hints for Unix Setups Cable Please consult the documentation that came with your workstation to find the part number of or information on how to make a serial cable for your workstation. The cable should be a hardware-handshaking cable. Please refer to Appendix A for a complete list of signals provided by the modem its serial port. Installation Modem settings Unix environments usually don’t like modem responses or echoing of commands. Therefore you should set ATE0Q1.
Your /etc/gettydefs should contain a number of definitions appropriate for your purpose. Choose or create one for a multi-speed modem with hardware-handshaking (if your cable supports this). Remember that the name tag must be the same as in /etc/initttab. A possible entry in /etc/gettydefs might be: MMULTI# B38400 CS8 CRTSCTS # B38400 SANE -ISTRIP HUP HUPCL CRTSCTS #@S login: #38400 (The above two lines are a single entry.
Chapter 23 ZyXEL MODEMS AND APPLE MACINTOSH The external models of the 2864 series modems may be connected to an Apple Macintosh computer. You may use the standard modem settings, with one exception: use AT&D0. Connector When you connect a ZyXEL modem to a Macintosh computer, make sure the cable is a hardware handshaking cable. These cables are readily available. The models Lisa, Macintosh 128 and Macintosh 512 don't provide hardware handshaking.
state of bit 3 (vsync) of the V1A1 chip's data register A determines which transfer method is used. If the bit is low, the serial port is used in asynchronous mode. If it is high, synchronous transfers are possible. You need special software which handles this bit. The standard drivers of the Communication Toolbox (part of Apple's system software) do not support this feature. In many of the low-end models (i.e., Classic, Classic II, LC and LC II), pin 7 is not connected.
Software for the Apple Macintosh All terminal programs which make use of the hardware handshaking feature can be used on the Apple Macintosh. Such programs are readily avilable as PD, shareware or commercial software. One of the most powerful shareware programs available is ZTerm. Fewer programs are available to make use of the ZyXEL's fax features. A commercial software which has found wide acceptance is FaxSTF.

Chapter 24 ZyXEL MODEMS AND ATARIS All external models of the ZyXEL 2864 series may be connected to Atari computers. The factory settings should work just fine with your Atari computer. Cable The standard Atari ST, Mega ST and Falcon 030 models provide just a single serial port, while the Mega STE and TT are equipped with 3 or 4 serial ports. Not all ports provide all of the signals which are needed for truely reliable communication. On the Atari ST, the port is a male 25-pin connector.
Hardware Tips While the 25-pin connector of the ST is 100% compatible with a PC connector and standard cables may be used, the maximum data rate on this port is restricted to 19200 bps. Kits are available which allow speeds of up to 57600 bps. If you want to use your Atari ST as an answering machine and use the ADPCM mode of your ZyXEL modem, you must install one of these extensions. More information on these kits and projects may be found in Fidonet or in Internet groups about the Ataris.
Using Rufus Some very old versions are irritated by the RINGING message during a dial-up if the RUFUS dial directory is used to initiate a call. Disable the RINGING message (ATS42.6=1) or even better, get a current version. Using Connect The shareware terminal software Connect makes use of the ZyXEL voice features. Make sure you use version 2.20 or later. Earlier versions are incompatible with the current ZyXEL firmware.

Chapter 25 ZyXEL MODEMS AND AMIGA You may connect any of the external models of the ZyXEL 2864 series to an Amiga computer. The default modem settings should work fine in most instances. Cable Among the Amiga computers, two versions of the serial port exist. The Amiga 1000 has a female 25-pin connector, the other models a male 25-pin connector.
Amiga Modem Pin 1000 other Pin 6 DSR DSR 6 7 Signal Ground 7 8 DCD DCD 8 20 DTR DTR 20 22 NC* RI 22 *. not connected Software Tips A number of PD and shareware telecomunication packages, fax and voice software are available in BBSs and from the major online services. Hardware Tips Amiga computers run under a multi-tasking environment. Therefore you should lock the serial port, but do not lock it to baud-rates higher than 38400 bps on the low-end models.
GLOSSARY Analog: Not digital. Analog quantities may have any value. Analog loopback test: Testing method in which the modem's analog output signal is connected to the analog input. Answer: In a connection between two modems, one modem works as the recipient (in answer mode) and the second modem as the initiator (originate mode). AppleTalk: A simple network to connect several computers directly with each other. AppleTalk is also the protocol according to which connected computers exchange data.
Bit rate: Count of data bits transmitted per time unit. The framing bits needed for asynchronous transfer are also counted in the calculation of the bit rate. In general, the bit rate is ten times the character rate. bps: Unit of the bit rate; bits per second. Carrier: The carrier is a modulated tone and is used by the modem to transfer the data.
Data packet: Block of data which is framed by error control groups. A block consists of up to 256 8-bit groups. Data packets are used in synchronous transfer. Data pump: The important module doing modulation and demodulation for a modem. The data pump is decisive for the quality and the speed of a modem's transfer capabilities. DCD: Data Carrier Detected – a control signal line of the RS-232C interface. DCE: Data Circuit Terminating Equipment or Communications Equipment – a modem is a DCE.
EEPROM: An Electronically Erasable and Programmable Read Only Memory. Such a device is used in ZyXEL modems to store settings and profiles. An EEPROM does not lose data when the modem is turned off. EIA: Electronic Industry Association (of North America); this organization was the first to draft a standard serial port (RS-232C). EPROM: Electrically Programmable Read Only Memory. A memory chip which may be programmed electronically, but must be exposed to ultraviolet radiation to be erased.

ITU-TSS: International Telecommunications Union - Telecommunication Standards Sector. New name for the standard making organization CCITT. See CCITT. Jumper: A small device to close a contact. If the jumper TS2 is closed on a ZyXEL internal card model, the modem will go into self-test at the next power-on.
Packed data: Data from which redundant information has been removed. Some file extensions denote packed files. Standard extensions are .ZIP, .ARC, .LZH, .TAR, .ZOO and others. If you transfer packed data don't use MNP5 compression. Parity: A method to check whether a character has been correctly transmitted in asynchronous transfer. Usual settings are even parity and odd parity. In a connection, the modems at both ends must use the same parity settings.
RS: Abbreviation of recommended standard. RTS/CTS: See CTS/RTS. RXD: Line for the received data on a serial port following RS-232C. Security function: Features of the ZyXEL modems which help deny illegitimate contacts to your computer system through telephone lines.
