Page 27: Modem And Fax Basics
Chapter 2 MODEM AND FAX BASICS This chapter is intended for those readers who want to know the details behind mo- dem and fax operations; what's going on behind the scenes. In addition to introduc- ing basic modem and fax terminology, this chapter helps users to understand and be able to utilize the available features.
Page 28: Rs-232C Or Eia-232D/E
RS-232C or EIA-232D/E RS-232C is the Recommended Standard (RS) of the Electronic Industries Associa- tion (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 neces- sary to redeﬁne a standard, or to revise it.

1200 bps modems and Bell 103 for 300 bps modems. Everyone follows the ITU-T standards now for newer and higher-speed modems. ZyXEL 2864 series modems support all the above mentioned modem standards and are compatible with existing modems. Type of Telephone Line The commonly used phone service is a 2-wire dial-up line.

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.
Page 31: At Command Set
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 signal- ing information transmission. Each B channel is for user data transmission at 64Kbps.
Page 32: V.25Bis Command Set
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 communica- tion. Error Correction In synchronous data communication, data is checked and corrected in the host by the so-called "link layer protocol"...
Page 33: V.42Bis And V.42
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.
Page 34: Modem As A Fax
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.
Page 35: Distinctive Ring
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.
Page 36: Automatic Redial / Call Hunting
Most modems will automatically redial a telephone number several times if a con- nection 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 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: •...
Page 52: Pc Parallel Port Operation
PC Parallel Port Operation If the modem's parallel port is connected to a PC's parallel port, the PC can com- municate 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.
Page 53: Zyxel Parallel Port Adapter
ZyXEL is developing a special parallel port adapter that will make parallel port trans- fers 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 han- dle the data.
Page 54: Firmware Update/Upgrade
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:...
Page 55: Dram Upgrade
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.

Page 111: At Command Set Summary
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 for- mat. 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.

Every block is framed by a start ﬂag (01111110) and an end ﬂag (01111110). The maximum data block size used in the 2864 series is 256 bytes. The maximum number of outstanding blocks without acknowledgement is 31 for 128-byte blocks. These values are adjustable according to the modem on the other side.
Page 124: Data Compression
2864 series modems support both V.42bis and MNP5 data compression protocols. Data compression needs an error-free data link to work correctly, otherwise the cor- rupted compressed data stream will ruin the decompression process.
Page 125: Run-Length Encoding
The modem adaptively builds a dictionary of string tokens according to data that appears. 2864 series modems support a dictionary size up to 2K string tokens. The input data characters are combined and checked for a matching string in the dictionary.

300 bps to 460800 bps. What DTE speed is optimized for your application depends on how fast your computer and communication soft- ware can process the serial port data. 2864 series modems use certain controls and commands to enable the modem to optimize its performance.

DTE. Turn ON the RTS and the modem will start sending data again to the DTE. In asynchronous full-duplex applications, the 2864 always responds to the RTS sig- nal as a ﬂow control signal. The 2864 defaults automatically to this hardware ﬂow control setting and it is a better choice.

Page 129: Synchronous Operation
SYNCHRONOUS OPERATION This chapter introduces you to the use of the 2864 series modem for synchronous oper- ation. 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 syn- chronous.
Page 130: Half-Duplex 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.

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 com- puter as an example, other mid-range systems and mainframes should be able to use the same strings.

Page 135: Leased-Line Operation
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 com- pany. 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.
Page 136: Power Level
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 leased- line connection, the transmission power is limited to -9dBm for the Omni 288P and to -3dBm for the Omni 288S.
Page 137: Auto-Handshake
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 hand- shake mode before you save the conﬁguration.
Page 138: Aborting From Leased-Line Operation
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. The dial backup line continues to be used indeﬁnitely. ATS34=0 Reattempts leased line after n minutes.

Page 142: Caller Number Delivery(Cnd)
With CND service, the phone company's central ofﬁce will send the coded caller information to the called station. This information is sent once between the ﬁrst and second rings. 2864 series modems can decode this caller information and present it to the connected computer/terminal during the second ring period as part of the call progress ring message.

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.

This is supported by the communication software on the computer. The 2864 series modems support both asynchronous and synchronous V.25bis di- aling. However, the internal card supports only the asynchronous mode because it is asynchronous only with its built-in asynchronous serial port. The modem sup- ports the bit-oriented HDLC (High-level Data Link Control) synchronous proto- col which most synchronous communication links use.

Page 149: Cellular Mode Operation
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 trans- missions over cellular phone links. Although most ZyXEL modems can provide the cellular mode, the U-1496P portable modem is specially designed for mobile use.
Page 150: Cellular Modems And Zycellular Technology
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 multi- path fading.

Youalso need to set the S0 register to a ﬁnite number to enable auto-answering. To further detail oper- ation in Class Z mode, the special command AT+FZF has been implemented to de- ﬁne the fax reception mode under Class Z operation.
Page 174 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 de- pends on the fax connection speed.
Page 175: Stand-Alone Fax Reception And Storing
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: Fax to DRAM and printer, hangs up if data.
Page 176 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 com- puter 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 com- ing in, have the fax program receive the fax calls, and then dump all stored fax pages to the fax program.

EDR (Extended Distinctive Ring) has been added to the ﬁrmware of all of the modems of the 2864 series. Refer to chapter 13 and S-regis- ters S40 and S51 regarding this feature. New capabilities or enhancements will be released in future versions of the ﬁrmware.
Page 179: Voice Command State
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 re- ports), 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).
Page 180: Voice Data 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).
Page 181: Events And Actions With Shielded Code
The ZyXEL 2864 series modems provide three ways to leave the Voice Receival State: A <DLE><!> shielded code is received from the DTE.

Page 184: Voice At Commands
<ETX> (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 re- turn 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.
Page 185: Supported Commands For Voice Mode Operation
Flow Control is necessary to match the DTE-DCE data rate to the line signaling rate and to the requirements of analog conversion of the voice signals and data. For ZyXEL 2864 series modems, both software XON/XOFF and hardware RTS/CTS ﬂow control are used whereas the software ﬂow control is the default setting. The DTE may turn off the ﬂow control, but some other method must be used to avoid...

Each 2864 series model has a set of different ﬁrmware code. The ﬁrmware is not exchangeable between different models. Since ﬂash EPROMs are used in the 2864 series modems, a ﬁrmware update is just a simple process of typing an AT command and uploading the ﬁrmware ﬁle. There is no need to open the modem case or program the EPROM.

Avoid this by sending ATS35.1=1 to the modem. Avoiding Disconnections when Making a Data Call The modems of the 2864 series return a RINGING message when the remote mo- dem does not answer on the ﬁrst ring. Some software packages confuse the RING-...
Page 218: Calling From An Extension / Blind Dial
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 re- ceive 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 neces- sary to disable the modem's dial tone detection since many systems do not provide a standard dial tone.

Page 221: Zyxel Modems And A Pc
ZyXEL MODEMS AND A PC All of the modems of the 2864 series may be used with a PC. If you install the in- ternal 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.
Page 222: Parallel Cable
Please consider this when you set up your modem's DTE to DCE speed. If you are using a ZyXEL 2864 modem’s parallel port for PC-modem communica- tion, setting the DTE speed has no actual physical meaning. The actual speed de- pends on how fast and efﬁcient the Windows program can run.

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 mo- dem, you must install one of these extensions.
