Hardware Installation Introduction This chapter describes how to install the ISIHI-2S card into the ISA bus on your personal computer. Hardware installation involves the following: • Opening your PC • Setting card configuration (determining I/O address DIP-switch setting and IRQ jumper setting) • Installing the card into the PC Computer Requirements • 386, 486, or Pentium®-based PC or compatible with ISA Bus Architecture • Microsoft Windows 95, Windows NT 4.0, SCO Open Server version 5.
Hardware Installation Before You Start Warning: Direct interconnection (or connection by way of other apparatus) of ports marked SAFETY WARNING see instructions for use with any other ports (whether similarly marked or not) may produce hazardous conditions on the network. Multi-Tech strongly urges you to consult a qualified engineer before attempting to make this type of connection. • All installation must be done by a qualified service person.
Hardware Installation Determine Current System Settings When you install a device into your computer, the processor must have a means of routing information to and from the device, and the device must have a means of gaining the processor’s attention. Input/Output (I/O) addresses route information to and from the device. Interrupt Requests (IRQs) gain the processor’s attention. The ISIHI-2S card requires eight I/O addresses and one IRQ value that are not used by any other device in your system.
Hardware Installation Installing the ISIHI-2S Installing the ISIHI-2S includes setting the I/O address DIP switches and the IRQ jumper. You can skip this this section if you select the default values. Default values are I/O address: 210 hex and IRQ: 10. 1. Before handling the ISIHI-2S, discharge any static in your body by toucing a piece of grounded metal such as the computer chassis. 2. Carefully remove the ISIHI-2S from its anti-static bag, handling it only by the mounting bracket and edges.

Chapter 3—Software/Driver Installation Configuring the Terminal Adapter Before you connect the ISIHI-2S to your network terminator, you must configure it to match your ISDN service and the remote TA. You can use any of the following methods: • ISDN TA Configuration Utility—recommended for computers with Windows 95 and Windows NT, version 4.0 operating systems. • ConfigMenu—recommended for computers with DOS or Windows 3.
Chapter 3—Software/Driver Installation Call Control Configuration • Persistent DTR Dialing ____________________ A high DTR (Data Terminal Ready) signal on the serial port indicates that your computer or terminal is ready to communicate with your TA. DTR normally goes high when a communication program starts or is ready to dial. Persistent DTR dialing enables the TA to automatically redial the number stored in memory location 0 whenever DTR is high, and the serial port does not have an active call.
Chapter 3—Software/Driver Installation To Configure the Terminal Adapter You can configure TAs with ISDN TA Configuration utility, ConfigMenu, or with AT commands. Instructions for all three are provided in this section. ISDN TA Configuration Utility 1. Before you start the ISDN TA Configuration utility, disconnect the ISIHI-2S by removing the RJ-45 cable from the ISDN jack. 2. Insert the diskette labeled Config Utility (ISDNTA). Click Start, Programs, and then the ISDN TA Configuration Utility icon. 3.
Chapter 3—Software/Driver Installation 5. The Configuration dialog box appears. Refer to your network configuration notes in Before You Start as you enter information to configure both TAs. If you have questions about choices, click Help. After entering information in each dialog box, click Next. 6. The Data Protocol Setup dialog box appears. Referring to you network configuation notes, enter the appropriate information; then click Next.
Chapter 3—Software/Driver Installation 7. The SPID dialog box appears. Referring to your network configuration notes, enter the appropriate information; then click Next. 8. In the Save Configuration dialog box, enter a name to store the configuration. Then click Next.
Chapter 3—Software/Driver Installation 9. To load the configuration, click Next in the Load Configuration dialog box. 10. Then click Finish in the Configured dialog box. The first TA now is configured. 11. Click Back to return to the Configuration dialog box and repeat steps 5 through 10 to configure the remaining TA(s). If you install multiple ISIHI-2S cards in the same PC, you must configure two TAs per card installed.
Chapter 3—Software/Driver Installation ConfigMenu Configuration Utility Use the ConfigMenu configuration utility with computers using DOS or Windows 3.x operating systems. ConfigMenu is installed in the TAs as part of the firmware. To use ConfigMenu: 1. Start a data communication program and select the COM port where the TA is connected. 2. In the communication program dialog box, type AT@Config and press ENTER. ConfigMenu’s Main Menu appears (see screen below). 3.
Chapter 3—Software/Driver Installation ConfigMenu Menus Network Configuration Menu—configures network parameters such as switch type, data and voice TEIs, and data and voice MSNs. When you finish, select Save Network Configuration to save your work. Call Control Configuration Menu—changes how the TA originates and answers calls. Options include Auto Answer, Rings to Answer, Dialing Method, and Persistent DTR Dialing. Data Protocols Menu—changes the rate adaption protocol used by the TA.
Chapter 3—Software/Driver Installation NetWare Connect (Novell) Driver Installation Multi-Tech Systems provides AIO drivers for the ISIHI-2S, so it can function with Novell compatible asynchronous applications (e.g., NetWare Connect). The AIO driver is simply an NLM (NetWare Loadable Module) that runs on the file server. Drivers must be loaded on the file server where the board is installed. Drivers can be loaded from the file server’s console prompt or incorporated for autoloading in the AUTOEXEC.
Chapter 3—Software/Driver Installation Troubleshooting Problem: I loaded the driver at the file server console, then I started NetWare Connect and connected a modem to a port on an ISIHI-2S. When I try to communicate with the modem, I see the DTR of the modem being raised, but the modem does not respond to my AT commands. Solution: There might be an IRQ conflict between an ISIHI-2S and some other hardware in your system.
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 system’s 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 1–4 characters. b board number Values of 1 through 4, depending on the number of ISIs installed. x port letter Values of A–H 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 system’s 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 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 Description File Format A description file may contain descriptions for multiple terminal types. Separate each terminal entry by a blank line. The first line for each terminal contains the various names by which that terminal is known. The three types of entries for each terminal emulation are hot key entries, terminal escape sequences, and timing specifications. Hot Key Entries These entries have three columns.
Chapter 3—Software/Driver Installation Timing Specification The timing specification is the interval in tenths of a second that the utility waits before checking for an escape sequence. The timing specification is defined below: Mnemonic time Description Specifies the interval, in units of 0.1 seconds, Multi_View waits while reading characters before checking for escape sequences.
Chapter 3—Software/Driver Installation The fullest potential of Multi_View is realized on a multiscreen terminal. However, Multi_View can be used on a dumb terminal that has only a single page of memory. When there is only one page, the screen output is unavoidably garbled from different virtual screen outputs. Some important ASCII unprintable characters and their octal values are listed below.

MODEM 4 AT Commands, S-Registers, and Result Codes MultiModemISI Hybrid Series, ISIHI-2S 63
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem Modem AT Commands The ISIHI-2S’s 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 Modem Note: Each character in a command counts toward the 40 character command line maximum. Example: Q1 is a single command, but it counts as two characters in the command line. Each command has a valid range of parameters; for example, &S can have only 0 or 1 as a parameter. Valid commands always generate an OK result code, and a few generate an additional response such as a list of parameters.

Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem Dialing Commands Use dialing commands to dial and hang up. Ds Dial s = phone number Default: none The letter D in a command causes the modem to dial the telephone number immediately following it. For example, if you type ATD5551212, the modem dials the number 555-1212. The ISIHI-2S modem supports several dialing methods. With the D command, you can specify either pulse (ATDP) or tone (ATDT) dialing.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem P, T Pulse or Tone Dialing Default: T The ISIHI-2S’s modems dials numbers by using pulse dialing, tone dialing, or a combination of both methods. Pulse dialing, used by rotary-dial telephones, uses the timed opening and closing of a relay to encode the numbers. Tone dialing, used by pushbutton (touch-tone) telephones, uses dual tone multifrequency (DTMF) dialing. P selects pulse dialing. T selects tone dialing.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Return to Command Mode After Dialing Enter a semicolon (;) as the last character of a dialing command to cause the modem to return to command mode immediately after executing the command instead of waiting for a carrier signal and going online. For example, type ATDT5551212; to tone-dial the number and immediately go back into command mode.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem Phone Number Memory Commands The modem 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 modem’s 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 The ISIHI-2S stores parameters in two places. It stores factory default parameters in read-only memory (ROM), and customized parameters in nonvolatile random access memory (NVRAM). You cannot change the default parameters in ROM, but you can change parameters in temporary memory and then store them in NVRAM as custom settings. You can then recall the custom settings as if they were factory default settings.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem Modem Response (Result Code) Commands ISIHI-2S modems can give responses to commands. The most common is OK, but the modems also can alert you or your software to dial tones, busy signals, connection speeds, and whether the connection is made with error correction or compression enabled. These responses are called result codes; they can be terse (numbers) or verbose (text).
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem X1 causes the modem to blind dial, but in addition to the basic CONNECT code, it provides extended codes consisting of the word CONNECT and the speed of the connection (CONNECT 14400 or CONNECT 28800, for example). In this mode, the modem does not recognize or respond to dial tones or busy signals. X2 causes the modem to wait for a dial tone before dialing.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem Online Connection Commands The following commands control the conditions of the online connection. Bn Answer Tone n = 0, 1, 2, 3, 15, or 16 Default: B1 and B16 The B command selects the frequency the modem uses for its answer tone. (The answer tone is the tone transmitted by the receiving modem to the calling modem, thus initiating the handshake between the two modems.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem &Gn Guard Tones n = 0, 1, or 2 Default: &G0 (models outside U.K.) or &G2 (U.K. models only) The &G command 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 Modem RS-232 Interface Commands These commands define how an ISIHI-2S modem uses and responds to standard RS232 signals. &Cn Carrier Detect Control n = 0 or 1 Default: &C1 The &C command lets you 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 Modem 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 modem’s error correction mode using the \N command. \N0 disables the modem’s V.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem 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. Do not precede this command with AT or press ENTER to execute it. In Information Request n = 0, 1, 2, 3, 4, or 9 Default: none This command displays specific product information about your modem.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem 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 Modem control lines. When an XOFF character is detected, the data stream is suspended until an XON character is detected. If you issue the &K4 command to the modem, it will respond to XON/XOFF pacing, and use XON/XOFF characters as its own method of flow control to the computer. (This is the same as &K4.) The drawback to using this method of pacing is that some files may contain these characters as part of the file data.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem \Kn Set Break Control n=5 Default: \K5 This command determines how the modem processes a break signal received from the local DTE during an online connection. \K5 causes the modem to send the break to the remote modem in sequence with transmitted data, non-destructive, non-expedited. +ES=6 Enable Synchronous Buffered Mode Default: none This command allows an H.324 video application direct access to the synchronous data channel.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem Diagnostic Commands Diagnostic commands help you troubleshoot your modem when problems occur. &Tn Self-Test Commands n = 0, 1, 3, or 6 Default: none The &T command causes the modem to perform various self-tests. &T0 causes the modem to stop any test currently in progress. &T1 causes the modem to perform a local analog loop test, which verifies modem operation and the connection between the modem and the computer.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes This chapter describes the ISIHI-2S’s S-registers, which 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 S-register and the Sr=n command to change it.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem S3 Return Character Unit: Decimal Range: 0–127 Default: 13 (^M) S3 defines the carriage return character by its decimal ASCII code. The default setting is the ^M character (decimal 13), which is the code for ENTER on most keyboards. S3 may be set for any ASCII character. Note: If you change the S3 value, you must make corresponding changes in your data communications software.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem S8 Pause Time for Comma Unit: 1 second Range: 0–65 (North America), 4–255 (International), 4–7 (UK) Default: 2 (North America), 4 (International and UK) S8 determines the length of the pause caused by a comma character in a dialing command. The default setting is two seconds for the North American model and four seconds for the International and UK models. S8 may be set for up to 65 seconds.
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem S37 Maximum Dial Line Rate Unit: decimal Range: 0–19 Default: 0 S37 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 Modem S89 Off-line Time Unit: 1 second Range: 0, 5-255 Default: 10 S89 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 off-line 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 Modem AT Commands that Affect S-Registers For maximum throughput, the ISIHI-2S’s default configuration is for originating a call to another 33,600 bps modem that supports error correction, data compression, and flow control. If the receiving modem is not compatible, the ISIHI-2S can match any ITU-T or Bell standard modem (but not proprietary protocols).
Chapter 4—MODEM AT Commands, S-Registers, Result Codes Modem Modem Result Codes Terse Verbose Definition 0 OK Command executed without error; ready for next command. 1 CONNECT Modem has detected carrier and gone online. 2 RING Modem has detected ring caused by incoming call. 3 NO CARRIER No carrier signal has been detected within the allowed time. 4 ERROR Error in command line (too many, or invalid characters). 5 CONNECT 1200 Modem detected carrier at 1200 bps and gone online.

Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Terminal Adapter 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.

RETURN Command Execution Values: n/a Default: n/a Press the RETURN (ENTER) key to execute a command. The RETURN key is sometimes abbreviated in command examples.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Terminal Adapter !C0=n Network Switch Type Values:n = 0, 1, or 5 Default: !C0=1 (Northern Telecom DMS-100) Use the !C0= command to select one of the seven network switch types supported by the ISIHI-2S. Factory default setting is !C0=1 (Northern Telecom DMS-100).
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Terminal Adapter *!D3=n TEI 1 Values:n = 0–63, 240 (auto), 241 (disable) Default: *!D3=240 (Auto TEI) Use the *!D3= command to set the ISIHI-2S’s 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.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes 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 0–9, the * character, and the # character.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Terminal Adapter Sr=n Set S-Register Values: r = 0, 2–5, 7, 10, 25, 32, 50-53; n varies Default: None Use to set 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 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. &C1 DCD goes from low to high when TA establishes a connection (DCD normal).
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Terminal Adapter &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 Terminal Adapter &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 Terminal Adapter &Zn=x Store Telephone Number Values: n = 0–9; 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 (0–9) 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.

Once the TA receives an AT command from the computer, it automatically adjusts to parity the computer is using.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Terminal Adapter Dn Dial Values: string of up to 25 characters Default: none Causes TA to dial a telephone number (e.g., ATD785-3500 ). Hn Hang Up Values: n = 0 or 1 Default: H0 Forces TA to go off-hook (to take control of the telephone line) or to go on-hook (hang up). Since the TA goes off-hook automatically when it dials, H command normally is used only to hang up.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes 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.g., S7=45.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Terminal Adapter S3 Carriage Return Character Unit: Decimal ASCII code Range: 0–127 Default: 13 (^M) Specifies the character used by the TA to indicate the end of a command line. S4 Line Feed Character Unit: Decimal ASCII code Range: 0–127 Default: 10 (^J) Specifies the character used by the TA to indicate the end of a status message.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Sets whether the mechanism for identifying the two endpoints of a connection is enabled or disabled. Since RING messages only appear for ISDN data calls, the CLI feature does not define a means of conveying Calling Party information to the terminal for ISDN voice calls.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Terminal Adapter 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 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. Modes of Operation The TA has three modes of operation: offline command, online command, and data.
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes Terminal Adapter 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 6 111
Chapter 6—Troubleshooting Guide Troubleshooting This chapter covers common problems you may have with your ISIHI-2S and how to solve them. Your ISIHI-2S was thoroughly tested at the factory before shipping. If you are unable to successfully connect, or if you experience data loss or garbled characters, during connecting, it is possible that the modem or terminal adapter is defective. However, it is more likely that the source of your problem lies elsewhere.
Chapter 6—Troubleshooting Guide The Terminal Adapter Does Not Respond to Commands • Make sure you issue commands from the data communications software, either automatically or manually, in terminal mode. (You cannot send commands to the TA/ modem from the DOS prompt.) • Make sure you are in terminal mode in your data communications program; then type AT and press ENTER. If you get an OK response, your connections are good and the problem likely is in your phonebook entry or session settings.
Chapter 6—Troubleshooting Guide The Terminal Adapter Dials But Cannot Make a Connection Possible be several reasons the TA fails to make a connection include: • Lack of a proper physical connection to the communication line • A busy signal • A wrong number • No terminal adapter at the other end • A faulty communications device, computer, or software at the other end • Incompatibility between communications devices • An improperly configured ISIHI-2S TA Narrow the list of possibilities by using extended res
Chapter 6—Troubleshooting Guide The Terminal Adapter Disconnects While Online • Check for loose connections between the computer, the ISDN jack, and AC power. • The problem may have originated at the other end of the line. Try again. • If you were online with a BBS or online service, it may have hung up due to lack of activity on your part or because you exceeded your time limit for the day. Try again. The Terminal Adapter Cannot Connect When Answering • Autoanswer may be disabled.

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 M5 (previously Generic Data M-1DN) • 2B Service • Alternate voice/data on each B channel • One directory number Not available for services provided with Northern Telecom or AT&T switches. Since two directory numbers are required for 2B operation, use Capability S. 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.
Appendix 5.
Appendix 8. Request the telephone company to provide 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.

Appendix Appendix L: AT Command Summary (TA) How To Use AT Commands Usually, your data communication software controls the ISIHI-2S terminal adapters for you. However, you may also want to use AT commands,which give you complete control over the TAs. Be careful using these commands because loose its ability to control the TA. If you find that an AT command causes a problem, turn the computer off and then back on to reset AT commands to the factory default settings.
Appendix COMMAND DESCRIPTION En Command Mode Echo n = 0 or 1 E0 Echo off E1 Echo on Hn Hang Up n = 0 or 1 Default: H0 Forces TA to go off-hook (to take control of the telephone line) or to go on-hook (hang up). Since the TA goes off-hook automatically when it dials, H command normally is used only to hang up. To hang up, first you must escape to command mode (+++AT ), then type ATH (or ATH0) . You also can include the hang up command in the escape sequence: +++ATH .
Appendix COMMAND 162 DESCRIPTION %En Escape Sequence Options n = 0–5 Default: %E1 and %E4 By default, the modem responds only to the +++ escape method. However, you can use the %E command to set the modem to respond only to the method, to respond to either +++ or the method, or to ignore both methods and not escape.

Glossary MultiModemISI Hybrid Series, ISIHI-2S 169
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 also be referred to as a bi-polar 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 Automatic Dialer: A device which is programmed to place a call to a predetermined number any time it is taken “offhook”. binary value. Binary also refers to a file format that uses 8bit characters , to allow for control characters (i.e., all nonASCII files). B BSC (Binary Synchronous Communications): Also called “bisync”, this communications protocol was the first synchronous data format used by IBM.
Glossary C CAD (computer aided design - pronounced “kad”): A computerized system used to design products. CAD systems are high speed workstations or PCs that use CAD software and input devices, such as graphic tables and scanners. Callback security: A security feature available in some intelligent modems that stores phone numbers. When activated, the user calling the secured modem must furnish a recognized password and then provide a code that corresponds to one of the stored phone numbers.
Glossary Data compression: The process of reducing the data bits necessary to represent useful information. By compressing files, less storage is required and higher throughputs are realized. Data Pump: The DAC (Digital-to-Analog Conversion) circuitry used within a modem. DB-25: A very common 25-pin connector often referred to as an RSs-232 connector because it is the connector over which the RS-232 interface commonly occurs.
Glossary ing contributions in electronics, and sets electronic interface standards, such as RS-23. EISA (Enhanced Industry Standard Architecture pronounced “eesa”): The purpose of the EISA bus was to provide a 32-bit bus for faster throughputs while maintaining backward compatibility with the classic ISA bus architecture. Emulation: The process of one type of device imitating another via a hardware or software package.
Glossary Hard Disk: A metal disk covered with magnetic recording material. Some can hold up to several gigabytes of information. Contrast with floppy disk. Hardware: The equipment that makes up your computer system, including the keyboard, mouse, disk drives, and monitor. Hexadecimal: A base 16 numbering system used to represent binary values. Hex uses the numbers 0-9 and the letters A-f; usually notated by an “h” (as in “4CF h”, read as “four charley fox, hex”).
Glossary LRC (Longitudinal Redundancy Check): An error checking method that generates a parity bit from the specified string of bits on a longitudinal track. In a row and column format such as on magnetic tape, LRC is often used with VRC, which creates a parity bit for each character. M Macro: A series of keystrokes, commands, and/or menu selections that have been recorded and assigned a key or key combination. When those keys are pressed, the macro is executed from beginning to end.
Glossary P Parameter: 1. A “place holder” in a command that should be substituted with useful information. 2. The list of acceptable values for a given option or command. Parity bit: An extra bit attached to each byte of synchronous data used to detect errors in transmission. PCB (Printed Circuit Board): A flat board that holds chips and other electronic components. The board is “printed” with electrically conductive pathways between components.
Glossary Resolution: Indicates the number of dots that make up an image on a screen or printer. The more dots, the higher the resolution, and the finer and smoother the images can appear when displayed at a given size. RJ-11: An industry standard interface used for connecting a telephone to a modular wall outlet; comes in 4-and 6-wire packages. RJ-45: An 8-wire modular connector for voice and data circuits. ROM (Read Only Memory): A memory chip that permanently stores instructions and data.
Glossary Toggle: Alternate back and forth between two states. Tone dialing: One of two methods of dialing a telephone, usually associated with push button phones. Compare with pulse dialing. Transistor: A 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 Workstation: Traditionally a dumb terminal connected to a host. However, with the advent of LANS and WANS, PCs that are connected to a LAN are now called workstations too, even though they are capable of independent processing. A workstation is simply an input/display device through which a user accesses a resource. X X.121: CCITT’s recommendation for unique addressing of each DTE connected to a communications network throughout the world. X.
