Introduction MultiModemISI Hybrid Series, ISIHI-2S/2U 1 5
Chapter 1—Introduction W elcome to Multi-Tech’s new MultiModem Hybrid Series, model ISIHI-2S/2U, a multiport hybrid ISDN card for Remote Access Server (RAS) applications. Included on the ISIHI-2S/2U are four V.90/K56flex central site modems for incoming analog modem and fax calls, as well as two terminal adapters. Each terminal adapter appears as two ports to the server PC using the ISIHI-2S/2U. The terminal adapters identify incoming analog calls and route them to the central site modems.
Chapter 1—Introduction From the perspective of the server PC, the ISIHI-2S/2U is an 8-port serial card with eight devices permanently attached to the serial ports. The first four ports are the two terminal adapters, each of which appear as two ports. The remaining four ports are the four central site modems. The chart below summarizes the correlation of ports and devices.
Chapter 1—Introduction Modem Description/Features ISIHI-2S/2U modems include an Intel 20 MHz 80186 processor and 254K of RAM that work dynamically to allocate resources to the most active modems. Simple to install, the ISIHI-2S/2U can be used to add multiport, Enhanced V.34 modem communications to a network host or server as easily as plugging in an expansion card, loading the driver software, and connecting the phone lines. The ISIHI-2S/2U contains four modems, which meet the proposed Enhanced V.
Chapter 1—Introduction Terminal Adapter Description/Features ISIHI-2S/2U terminal adapters have S/T ports to connect to the ISDN network and analog ports to connect to a telephone, modem, or fax machine. They ship with a software configuration utility for Windows® 95, Windows NT, and ConfigMenu (a built-in configuration utility for DOS and Windows 3.x operating systems). The TAs also accept AT commands, enabling them to use the same communications software as analog modems.
Chapter 1—Introduction The name of the S/T bus comes from the letters used in the ISDN specifications to refer to two reference points, S and T. Point T refers to the connection between the NT1 device and customer supplied equipment. Terminals can connect directly to NT1 at point T, or there may be a PBX (private branch exchange, e.g., a customer-owned telephone exchange). When a PBX is present, point S refers to the connection between the PBX and the terminal.

Chapter 3—Software/Driver Installation Configuring the Terminal Adapter Introduction North American users must configure the terminal adapter to match network switch type, the service profile identifier (SPID), and the directory number (DN). For international users, the terminal adapter ships already configured for NET3, which should work on most phone lines in Europe. However, you may want to customize settings, regardless of your location. (See Optional Settings on the following page.
Chapter 3—Software/Driver Installation Optional Settings Data TEI _______________________________ The Data TEI is the TEI (terminal endpoint identifier) assigned to the data channel. You can select Auto TEI, a fixed TEI, or Disable. A TEI is a number used by the central office switch to uniquely identify each device that is connected to the network. When it uses dynamic TEI assignments (Auto TEI), the central office switch assigns a TEI each time the TA connects to the network.
Chapter 3—Software/Driver Installation ISDN TA Configuration Utility 1. Before you start, disconnect the ISIHI-2S/2U by removing the RJ-45 cable from the ISDN jack. 2.

Chapter 3—Software/Driver Installation SCO Open Server 5 Driver Installation The installation utility provided by SCO is called custom. This section provides a brief guide for opening the utility and installing the driver. The instructions below should be used only on SCO Open Server 5 systems. When you have completed the steps below, go to Multi-Tech Installation Script, which immediately follows this section. 1.
Chapter 3—Software/Driver Installation The Multi-Tech Installation Script This section guides you through the Multi-Tech Installation Script for SCO and UNIXWare systems. The script requests information such as how many boards you want to install, what I/O address and IRQ values (interrupt requests) you have selected, and how many pseudo devices you want to create for Multi_View utility. This information extracts the necessary drivers, which will be linked with your systems kernel. 1.
Chapter 3—Software/Driver Installation The following describes the format used in naming ISI ports: Default device name and format: ttyl ttyl basename This prefix is applied to all ISI ports on all boards. Base names contain 14 characters. b board number Values of 1 through 4, depending on the number of ISIs installed. x port letter Values of AH for ISI ports. (SCO UNIX values A-H indicate modem ports.) Device base name selected: _________________ 7.
Chapter 3—Software/Driver Installation Activating Ports in SCO Open Server 5 SCO Open Server 5 provides a device database that monitors the activity of serial ports through which users can log onto the host. If your ISI ports are used by terminals (e.g., to allow users to log onto your host), you must create an entry in the systems device database that furnishes specific information for the terminals that will be used on each ISI port. The database is referenced each time a user attempts to log in.
Chapter 3—Software/Driver Installation Multi_Setup Utility This section guides you through the Multi_View Utility for SCO and UNIXWare systems. While installing the ISIHI-2S/2U drivers, you also install the Multi_View utility for multiple page terminals. This section profiles the Multi_View utility and gives you the necessary information to create a Multi_View information file.
Chapter 3—Software/Driver Installation To define your own terminal capability database, refer to the Description File Format below. The following options are defined: -h Prints the Help file. Multi_View uses the environment variable MTDSPLY to choose the utility to display this file. If no such variable is found in the environment, then Multi_View uses the pg utility. -t Informs Multi_View to use a terminal description different from the one specified by the TERM variable in the user environment.
Chapter 3—Software/Driver Installation Terminal Escape Sequences The terminal escape sequence entries describe the escape sequence to be sent to the terminal. The first column contains a mnemonic, which are described below: Mnemonic Descripion ps Describes the escape sequence to send to the terminal to switch to the appropriate physical page. The physical pages are numbered in the order they are specified in the description file. clear Specifies the escape sequence to clear the screen.
Chapter 3—Software/Driver Installation Each character in the escape sequence or hot key can be specified as an ASCII character if it is printable. If not printable, it should be specified in an octal format with leading 0s and preceded by a \. For example, an ASCII escape character can be specified as \033. Do not switch the screen while outputting; it can break the escape sequence sent to the terminal. When there is more than one virtual screen, all outputs from the inactive virtual screens are blocked.
Chapter 3—Software/Driver Installation Linux Driver Installation To install the Linux driver: 1. Insert the driver installation diskette. 2. Prepare a temporary installation directory: mkdir isicom 3. Change your current directory to the temporary installation directory: cd \isicom 4. Place the isicom.tar file into the isicom directory. 5. Then extract the file using the tar utility: tar xvf /isicom/isicom.tar 6.
Chapter 3—Software/Driver Installation Miscellaneous: Device files corresponding to ports on the ISIHI-2S cards are created in the /dev folder. Use ttyMxy for normal ports and cumxy for corresponding callout ports. The letter x is the card number (14), and y is the port number, (ap) for 16-port cards. Normal ports (ttyM) are configured for dial-in connections. Callout ports (cum) are used for dial-out connections.
MODEM 4 AT Commands, S-Registers, and Result Codes MultiModemISI Hybrid Series, ISIHI-2S/2U 67
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem AT Commands ISIHI-2S/2U modems are controlled by instructions called AT commands, so called because the attention characters, AT, precede each command or sequence of commands (known as a command string). You can send commands to the modem from your keyboard while in terminal mode, or you can use communications software to issue these commands automatically. The modem is in command mode when it is not dialing or online.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes A parameter after a command (0, 1, 2, etc.) tells the modem which option to use. If you do not specify a parameter, the modem assumes the 0 (zero) option. E, for example, is the same as E0. You can issue several commands on a single line (a command string) as long as the line does not exceed 40 characters. Note: Each character in a command counts toward the 40 character command line maximum.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Topic Dialing Action, p. 71 Dial Modifiers, p. 71 Phone Number Memory, p. 72 Configuration Storage & Recall, p. 72 Modem Responses (Result Codes), p. 73 Online Connection, p. 75 RS-232 Interface Controls, p. 77 Error Correction & Data Compression, p. 78 Immediate Action, p. 79 Flow Control, p. 80 Escape Sequences, p.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Dialing Commands Use dialing commands to dial and hang up. Ds Dial s = phone number Default: none Causes the modem to dial the telephone number immediately following it. For example, if you type ATD5551212, the modem dials the number 555-1212. Hn On-Hook/Off-Hook n = 0 or 1 Default: 0 Makes the modem hang up (go on-hook) or simulate the action of picking up a telephone handset (go off-hook).
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Phone Number Memory Commands ISIHI-2S/2U modems can store up to four telephone numbers in nonvolatile memory. You can store the numbers with the &Z command and dial them with the ATDS command. &Zn=s Store a Phone Number s = phone number n= 0, 1, 2 or 3 Default: none You can store a telephone number string in the modems phone number memory. You can store four of these strings using the &Zn=s command. The memory locations are labeled N0 through N3.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Zn Reset Modem n = 0 or 1 Default: none The Z command resets the modem to the configuration last saved by the &W command. The default values come from the customized configuration in NVRAM. Z1 is the same as Z0, and functions identically. &Yn Select Stored Configuration for Hard Reset n=0 Default: 0 This command is included for compatibility with applications that issue the &Y0 command. Modem functions are not changed.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes V0 (or V) displays the modems result codes as a number. V1 displays result codes as text. V2, an additional command given anytime after ATV1 is entered, displays the connect message of both the local modem and the remote modem. Xn Result Codes and Call Progress Selection n = 0, 1, 2, 3, 4, 5, 6, or 7 Default: X4 Selects which result codes the modem provides in command mode and determines whether the modem uses smart dialing or blind dialing.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes &Qn Asynchronous Communications Mode n = 0, 5, or 6 Default: &Q5 Allows you to select the type of asynchronous communications mode for your modem. Note: These commands are the same as several of the \Nn commands, described later in this chapter. &Q0 selects asynchronous mode with data buffering. This is the same as \N0, nonerror correction mode with data buffering. &Q5 selects error control with data buffering. This is the same as \N3, V.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes F Dummy command &Gn Guard Tones n = 0, 1, or 2 Default: &G0 (models outside U.K.) or &G2 (U.K. models only) Controls the presence or absence of guard tones from the transmitter when in answer mode at either 1200 or 2400 bps. Guard tones are used in Europe and other areas to allow the modem to function in the telephone systems. Guard tones are not used in the United States. U.K. models are locked at &G2 (1800 Hz guard tone).
Chapter 4—MODEM AT Commands, S-Registers, Result Codes RS-232 Interface Commands These commands define how the ISIHI-2S/2U modems use and respond to standard RS-232 signals. &Cn Carrier Detect Control n = 0 or 1 Default: &C1 Allows you to control the Carrier Detect (CD) signal on the RS-232/V.24 interface. This is a signal from the modem to your computer indicating that the carrier signal is being received from a remote modem.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Error Correction and Data Compression Commands You can configure modems to any of three different V.42 modes of operation (with or without compression): non-error correction, auto-reliable, and reliable modes. You also can turn data compression on or off. \Nn Error Correction Modes n = 0, 1, 2, 3, 4, 5, or 7 Default: \N3 Select the modems error correction mode using the \N command. \N0 disables the modems V.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes %Cn Data Compression n = 0 or 1 Default: %C1 The %C command allows you to disable data compression. Data compression is normally enabled. %C0 disables V.42bis/MNP 5 data compression. %C1 enables V.42bis/MNP 5 data compression. Immediate Action Commands Use immediate action commands to obtain information about AT commands and current modem settings. A/ Repeat Last Command Default: None Type A/ to repeat the previous command.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Flow Control Commands Flow control refers to techniques used by data terminal equipment and the modem to pause and resume the flow of information between them. It prevents a device from accepting more data than it can handle. The modem implements flow control in both directions. When the modem halts the flow of data, it is called flow control. When the computer halts the flow, it is called pacing.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes The drawback to using this method of pacing is that some files may contain these characters as part of the file data. If such a file is transferred using a modem with XON/ XOFF flow control enabled, the file transfer could fail due to indefinite suspension. \Q3 enables modems use of Clear to Send (CTS) signal on the RS-232/V.24 interface to regulate data flow. When CTS drops, data flow is suspended until the signal goes high (on) again.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Escape Sequences Escape sequences are also known as escape codes. They are used to cause the modem to enter command mode from online mode without disconnecting the call. +++ATIn-Band Escape Sequence If the modem is online with a remote modem, you can cause the modem to enter command mode without disconnecting the call by typing an escape code.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem S-Registers S-registers are small regions of memory where modem configuration information is stored. Whereas AT commands tell a modem what to do, S-registers tell the modem how to do it. Each S-register has a name that consists of the letter S and a number (S0, S1, S2, etc.), hence the term S-register. Use the Sr? command to read the value stored in an Sregister and the Sr=n command to change it.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Note: If you change the S3 value, you must make corresponding changes in your data communications software. S4 Line Feed Character Unit: Decimal Range: 0127 Default: 10 (^J) Defines the line feed character by its decimal ASCII code. Default setting is ^J (decimal 10), the code for the line feed key on most keyboards that have such a key. Can be set for any ASCII character.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes S8 Pause Time for Comma Unit: 1 second Range: 065 (North America), 4255 (International), 47 (UK) Default: 2 (North America), 4 (International and UK) Determines the length of pause caused by a comma character in a dialing command. Default setting is two seconds for North American model and four seconds for international and UK models. S8 can be set for up to 65 seconds.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes S37 Maximum Dial Line Rate Unit: decimal Range: 019 Default: 0 Sets the maximum dial line rate. When set to zero (0), the maximum dial line rate is the same as the maximum modem speed. This is the most common setting and allows other modem functions to actually determine the line rate used for each connection. It is the default. Consider using S37 to set a maximum dial line rate if you need to artificially retain a lower modem speed.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes S89 Off-line Time Unit: 1 second Range: 0, 5-255 Default: 0 Sets the length of time, in seconds, a modem waits in the off-line command mode before it goes into standby mode. If S89 is set to 20 seconds, the modem waits 20 seconds in offline command mode before going into standby mode. Setting S89 to zero (0) prevents the modem from ever entering standby mode.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Reading and Assigning S-Register Values Use the S command to assign a value to an S-register and to read an its current value. To read an S-register value, in terminal mode, type S, the S-register number, and a question mark (?), and press ENTER. For example, to display the value of register S7, type ATS7? and press ENTER. The value appears as a three-digit decimal number (e.g., 045).
Chapter 4—MODEM AT Commands, S-Registers, Result Codes The &W0 (or &W) command stores all current AT command and S-register values into nonvolatile random access memory (NVRAM) and configures the modem so that it reads your custom settings in NVRAM when the modem is turned on or when it is reset with the Z command. (The &F reset command will continue to read the factory default settings in read-only memory [ROM].
Chapter 4—MODEM AT Commands, S-Registers, Result Codes 88 DELAYED Delay is in effect for the dialed number. 89 BLACKLISTED The dialed number is blacklisted. 90 BLACKLIST FULL The blacklist is full. Extended Result Codes.
TERMINAL ADAPTER 5 AT Commands, S-Registers, and Result Codes MultiModemISI Hybrid Series, ISIHI-2S/2U 91
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Terminal Adapter AT Commands One of the ways you can communicate with and configure your terminal adapter (TA) is to use AT commands. AT commands are so-called because, with only a few exceptions, each command string begins with the characters AT. Using AT commands, you can read and set parameters and perform actions such as dialing.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Topic Command Execution, p. 94 Switch Configuration, p. 94 Serial Port Configuration, p. 97 Data Call Commands, p.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Command Implementation AT Attention Code Values: n/a Default: n/a AT precedes all command strings except the A/ command and escape codes. RETURN Command Execution Values: n/a Default: n/a Press the RETURN (ENTER) key to carry out a command. The RETURN key is sometimes abbreviated in command examples.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes !C0=n Network Switch Type Values:n = 0, 1, 2, or 5 Default: !C0=2 (InternationalNET3) !C0=5 (USAUS N1-1) Selects one of the network switch types supported by the ISIHI-2S/2U. International factory default setting is !C0=1 (Northern Telecom DMS-100). Default for USA is !C0=5 (USAUS N1-1).
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes *!D3=n TEI 1 Values:n = 063, 240 (auto), 241 (disable) Default: *!D3=240 (Auto TEI) Sets the terminal endpoint identifier (TEI) for channel 1. A TEI is a number used by the central office switch to identify uniquely each device that is connected to the network. When it uses dynamic TEI assignments (auto TEI), the central office switch assigns a TEI each time the TA connects to the network.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes *!N1=n DN 1 Values:n = 24-character string Default: null string Sets directory number (DN) for channel 1. The directory number is telephone number assigned to the TA at subscription time by the ISDN service provider. The DN is a string of up to 24 characters; valid characters are 09, the * character, and the # character.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Sr=n Set S-Register Values: r = 0, 25, 7, 10, 25, 32, 50-53; n varies Default: None Sets the value of an S-register, where r is the number of the S-register, and n is the value you want to set. (For more information on S-Registers, see Chapter 6, Terminal Adapter S-Registers.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes &Cn DCD Control Values: n = 0, 1, or 2 Default: &C1 (DCD normal) Controls behavior of the DCD (Data Carrier Detect) signal. Normally, the DCD goes high when the TA establishes a connection and drops when the connection is lost. However, you can force DCD to remain high at all times or to remain high except for a brief drop following a disconnect. &C0 DCD is forced high at all times.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes &E5 XON/XOFF flow control. This is an in-band method, where the XON and XOFF characters (^Q and ^S, respectively) are inserted into the data stream, rather than using separate control lines. When an XOFF character is detected, the data stream is suspended until an XON character is detected. The drawback to this method is that some files may contain these characters, causing the file transfer to be suspended indefinitely.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes &Rn CTS Control Values: n = 0, 1, or 2 Default: &R1 (CTS forced high) Allows you to control the state of the CTS (Clear to Send) signal. Normally the CTS signal follows the state of the RTS signal when TA is online. &R0 CTS acts normally; that is, it follows RTS. &R1 CTS is forced high, but still provides online flow control. &R2 CTS is forced high, but it drops on disconnect for the period of time set by S10.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes &Zn=x Store Telephone Number Values: n = 09; x = dial string Default: n/a Allows you to store a telephone number in a memory register for faster dialing. To store a number, type &Z, the register number (09) where you want to store the number, the = character, and the dialing string you want stored. Then press ENTER. The dialing string can have up to 80 characters. To read a stored number, type AT&Zn? (e.g.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes %E3 Both +++ and escape methods %E4 Disable OK response to +++ %E5 Enable OK response to +++ %E1 %E5 Enable +++ method and OK response to +++ %E3 %E5 Enable +++ or method and OK response to +++ @P3=n Parity at Power-Up Values: n = 04 Default: @P3=4 (None) Use only to set the type of parity the TA uses when turned on.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Data Call Commands Use these commands to make or configure data calls. A Answer Call Values: none Default: none Forces TA to answer an incoming call. To cause the TA to autoanswer, set register S0 to a value higher than 0. Dn Dial Values: string of up to 25 characters Default: none Causes TA to dial a telephone number (e.g., ATD785-3500 ).
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Terminal Adapter S-Registers S-registers are sections of memory in which values are stored that affect how the TA operates. S-registers are so-called because each has a name that begins with the character S. Use the S command to assign a value to or to read the current value of an S-register. To assign a value to an S-register, use the command Sr=n, in which r is the register number, and n is the value you want to assign to the register, e.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes S2 Escape Character Unit: Decimal ASCII code Range: 0127 Default: 43 (+) Specifies the character used by the TA to escape from data mode and return to command mode. S3 Carriage Return Character Unit: Decimal ASCII code Range: 0127 Default: 13 (^M) Specifies the character used by the TA to indicate the end of a command line.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes S32 Escape Sequence Timeout Unit: 100 ms Range: 0255 Default: 20 Sets the time allowed in an escape sequence from the receipt of the A in AT to the receipt of the carriage return. If the S32 time interval expires before you press E NTER, the escape sequence ends. The default time is 2 seconds.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Terminal Adapter Result Codes When the TA receives an AT command from the computer or terminal, it attempts to execute the command, then sends a status message to the computer or terminal that reports the result of the command. The TA provides you with several of these response messages, or result codes, which can be displayed on your monitor or intercepted and used by your communications software.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Using AT Commands to Operate the Terminal Adapter You can configure and operate the Terminal Adapter entirely with AT commands, if you want. Remember, you can issue AT commands only from a terminal or from a computer running a communications program in terminal mode. This section describes how to use AT commands for basic operations such as calling, answering a call, and hanging up.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Storing a Telephone Number To store a telephone number, type &Zn=x in terminal mode, where n is the number of the memory register in which the number is to be stored, and x is the dial command string that you want to store. For example, type AT&Z9=612-785-3500 to store the number 612-785-3500 in memory register 9.
Troubleshooting MultiModemISI Hybrid Series, ISIHI-2S/2U 6 111
Chapter 6—Troubleshooting Guide Troubleshooting This chapter covers common problems you may have with your ISIHI-2S/2U and how to solve them. The ISIHI-2S/2U was thoroughly tested at the factory before shipping. If you are unable to connect successfully, or if you experience data loss or garbled characters, during connecting, it is possible the modem or terminal adapter is defective. However, it is more likely that the source of your problem lies elsewhere.
Chapter 6—Troubleshooing Guide Peripheral expansion cards, such as bus mouse and sound cards, may include a serial port preconfigured as COM1 or COM2. The extra serial port, or the card itself, may use the same COM port, memory address, or interrupt request (IRQ) as your communications port. Be sure to disable any unused ports. To look for address or IRQ conflicts if you use Windows 3.1x, select File then Run in Program Manager. Type MSD and press ENTER.
Chapter 6—Troubleshooting Guide If the modem/TA reports BUSY, the other number may be busy. Try again later. If the TA reports NO CARRIER, no connection was made. You may have dialed the correct number, but the other computer or software was turned off or faulty. Check the number and try again or try calling another system to make sure your TA is working.
Chapter 6—Troubleshooing Guide File transfer appears slower than it should If you have a Universal Asynchronous Receiver/Transmitter (UART) that is compromising data throughputs, we recommend you replace it with a special I/O card. If you are running under Windows 3.1 and have a 16550AFN UART, you must replace the Windows serial driver, COMM.DRV, to take full advantage of the UARTs speed.

Appendix Appendix C: Pin Assignments The MultiModem Hybrid Series comes with either U-interface or S/T-interface network connection cable, and analog fax/modem DAA. The U-interface connection cable is for direct ISDN line connection, which does not need any extra ISDN NT1 device. The S/Tinterface connection cable is for connecting to NT1. Both the U- and S/T-interface use an RJ-45 phone jack but with different pin assignments.
Appendix Appendix D: ISIHI-2S/2U Testing Utilities This disk contains two files to be used in conjunction with MultiModemISI boards. These files are described in two sections: Operation with factory default settings (file name: ISI608.BIN) Operation with other than the factory default settings (file name: 608TERM.EXE) Note: This program is a DOS utility. 1. Operation with factory default settings: The 608TERM.
Appendix This step allows selection of a baud rate for testing. Once a baud rate is selected, the following displays: ISI Terminal Utility is ready. Press F10 to Exit. This message indicates that keyboard entry can now be performed. Any characters typed on the keyboard are sent through the MultiModemISI board to the modem and then returned to display on the PC screen. When operation is verified, exit the utility by pressing F10. 2. Operation with setting other than factory defaults The 608TERM.
Appendix The following displays: A:\>608TERM -A2C0 Loading Firmware to ISI608 located at address 2C0h Loading default file: ISI608.BIN ISI608 loading firmware . . . ISI608 verifying firmware . . .

Appendix Appendix F: Ordering ISDN BRI (2B+D) Lines Two ways to specify your ISDN line configuration to your service provider are: Use ISDN ordering codes where the user and the Local Exchange Carrier (LEC) or Internet Service Provider (ISP) use common nomenclature to describe elements of service. Use a building block approach where the naming conventions are not standard, and the user and provider must establish a set of provisioning options.
Appendix Bearer Service Circuit Switch Voice bearer (CSV) and Circuit Switch Data bearer (CSD) are broad categories of bearer service options that the phone companies can provide. Bearer services provide different types of guarantees about the reliability and synchronization of the data. Currently, there are ten different bearer services for circuit-mode and three services for packet mode.
Appendix Capability R (previously Generic Data I) 2B service Data only on each B channel Two directory numbers Applications include: 115.2K or 128 Kbps data only (no voice capability) Generic 115.2K/128 Kbps data transfer applications (including remote access and LAN/WAN connectivity and telecommuting) I2 (previously Generic Data I-1DN) 2B service Data only on each B channel One directory number Not available on the Northern Telecom switch.
Appendix Applications for Capability S include: 115.2K or 128 Kbps data 56K/64K bps data with voice or modem support Generic 115.2K/128 Kbps data transfer applications (including remote access and LAN/WAN connectivity and telecommuting).

Since two directory numbers are required for 2B operation, use Capability S.
Appendix Ordering ISDN Without IOCs The form below can guide you and your telephone company in specifying and obtaining ISDN service when IOCs are not used. To support most ISDN TA features, telephone service must meet certain requirements. These requirements are described in the following sections. Some features may be added or deleted, depending on your actual data service needs and availability in your area. Before ordering, talk to your telephone company about which services are provided in your area.
Appendix 5.
Appendix 8. Request telephone company to provide the following ISDN TA configuring information (record here): ISDN Switch Type: ____________________ ISDN Switch Protocol Version: ___________ ISDN Phone Number 1: ________________ ISDN Phone Number 2: ________________ (if 2B+D ordered) ISDN Line Type: ______________________ (point-to-point or multipoint) If MultiPoint, SPID Number 1: ___________ (with prefix and suffix) If MultiPoint, SPID Number 2: ___________ (with prefix and suffix) 9.
Appendix The 5ESS switch provides supplementary features that the ISDN TA may not support. Enabling these features may have undesirable consequences.
Appendix For More Information Several national and state organizations have ISDN line ordering information that can help when provisioning an ISDN BRI line. National ISDN Users Forum (NIUF) The National ISDN Users Forum (NIUF) implemented a series of Compatibility Packages (IOCs) to standardize and simplify ISDN ordering.

Appendix Appendix H: Dial Pulses and Tones Dial Pulses When you pulse dial, as when you make a call with a rotary dial telephone, your telephone or modem generates codes in the form of pulses that simulate the opening and closing of old-fashioned electric relays, or switches. The number of pulses in a code is the same as the digit they encode; thus, the digit 1 is represented by one pulse, the digit 2 by two pulses, etc. In the figure below, the digit 2 is pulse dialed, followed by the digit 1.
Appendix The extended DTMF characters (A, B, C, D) are the high-end frequencies (1633 Hz) defined on some telephone sets with a fourth vertical column of buttons.

Glossary A AC (alternating current)A power source whose signal crosses a reference voltage (usually called ground or zero). Alternating between a maximum and minimum voltage, AC may be referred to as a bipolar signal. Contrast with DC. ACK (ACKnowledgment code, pronounced ack)A communications code sent from a receiving modem to a transmitting modem to indicate that it is ready to accept data. It is also used to acknowledge the error-free receipt of transmitted data. Contract with NAK.
Glossary bandRange of frequencies between two defined endpoints. bandwidthThe transmission capacity of a computer channel, communications line or bus. It is expressed in cycles per second (hertz), the bandwidth being the difference between the lowest and highest frequencies transmitted. The bandwidth of a phone line is about 3000 Hz with QAM, you get up to 14,400 bps. Bandwidth is often stated in bits or bytes per second.
Glossary checksumA control field found in synchronous data packets which contain the results of the error control algorithm used. chipAlso called integrated circuits (IC), they are squares or rectangles that contain from a few dozen to a few million electronic components. CHKDSK (pronounced check disk)External DOS command that reports free memory and disk space. CHKDSK must be run directly from DOS or within a batch file. circuitAny closed path through which electrical current can flow.
Glossary only high or low at any given time. Therefore, digital signals may be cleaned up (noise and distortion removed) and amplified during transmission. DIP switchA set of tiny toggle switches, built into a DIP (dual in-line package), used for setting configurable parameters on a PCB (printed circuit board). directoryA logical subdivision of a computers disk space used to organize a group of files. A directory can be thought of as a file drawer.
Glossary a square envelope or cartridge. A disk drive holds the floppy disk through the hole in its center and spins it within its envelope. It can be used over and over again. Contrast with hard disk. flow controlThe process of regulating the speed at which data enters or leaves a serial port. Software flow control is implemented by communications software or by the user sending predefined characters or packets which are recognized as pause and resume indicators.
Glossary directly to the communications channels that interconnect terminals and computers. kermitAn asynchronous file transfer protocol noted for its megabyteOne million bytes, when describing a data rate. accuracy over noisy lines. 1M of disk space may actually mean 1,048,576 bytes. kernelThe core of an operating system that interacts mid-range computerA term coined by IBM, referring to directly with the system hardware. While most operating any of their Advanced Business Systems computers.
Glossary computer what to do. PROM (programmable read only memory)A permanent memory chip that can be programmed or filled by the customer after the manufacturer sets initial values.

The rules governing the transmitting and receiving of data.
Glossary manipulate the data. Before a PC can do anything useful, it must move programs from disk to RAM. When you turn it off, all information in RAM is lost. rebootRestarting your PC by turning off the power and then turning it back on, or by pressing Alt, Ctrl,, and Del keys at the same time. Warm boot=Ctrl+Alt+Del (soft boot) or Cold boot=Power switch (hard boot). repeaterA device that amplifies or regenerates the data signal in order to extend the distance of the transmission.
Glossary tone dialingOne of two methods of dialing a telephone, usually associated with push button phones. Compare with pulse dialing. transistorA semiconductor device used to amplify a signal, or open and close a circuit. In digital computers, it functions as an electronic switch. TSR (terminate and stay resident)A software program that remains active and in memory after its user interface is closed. Similar to a daemon in UNIX environments.
Glossary country and PDN), and a ten-digit national terminal number. X.21CCITTs recommendation for a 15-pin, digital interface. It is not widely accepted, because of the analog loops still prevalent in data communications. For this reason, CCITT introduced the X21bis standard for use with synchronous modems. X.25CCITTs definition of a three-level packet-switching protocol to be used between packet-mode DTEs and network DCEs. X.25 corresponds with the lower three/four layers of the seven layer OSI model.
