With Dial Security, you can prevent unauthorized access to a system through the use of password prompting and dial-back. Testing ITU-T V.54 loopback testing is available. The Courier can perform analog, digital, and remote digital loopback tests to determine if there are problems with the phone line, the remote device, or your Courier's transmitter or receiver. Flash ROM Upgradability Courier modems are software-upgradable using XMODEM file transfers and U.S. Robotics Software Download (SDL) application, allowing you quick, easy access to updates of your Courier's technology. The latest upgrades can be obtained on the U.S. Robotics web site or Bulletin Board System. Plug and Play Support for Windows 95 The software for the external and internal Courier has been developed to support Plug and Play (as defined by the Plug and Play External and Internal COM Device Specification, Version 1.00). When you connect your Courier to a computer that uses a Plug and Play operating system, the computer automatically detects and configure itself to the support your Courier. Remote Configuration and Diagnostics You can remotely configure and test your Courier. If you are a network administrator supporting remote users, this feature can save you time and money. Terminal Adapter Features ISDN Terminal Adapter The I-modem is an ISDN terminal adapter; it enables your computer to 1-2 Courier I-modem Getting Started Guide communicate on the ISDN at speeds of up to 64 kbps. Optional Built-in NT-1 The I-modems with Integrated NT-1 contain an on-board NT-1, sparing you the expense and extra cabling associated with an external NT-1. Optional Analog Device Jack The I-modem with Integrated NT-1 and Analog Device Jack allows you to plug in an analog telephone, fax machine, or modem, allowing analog devices to communicate over an ISDN B-channel. This applies to external units only. TurboPPP TurboPPP is U.S. Robotics' unique combination of asynchronousto-synchronous PPP conversion, compression, multilink PPP (ML-PPP). You can use TurboPPP to access the Internet or remote local-area networks (LANs) at speeds of up to 128 kbps before compression and up to 512 kbps with compression. Rate Adaptation The I-modem's support of the V.120 and V.110 protocols allows it to map slower-speed asynchronous data to the 64-kbps B-channel. The I-modem's rate adaptation capability spans the range of 300 to 57600 bps. Central Office Switch Compatibility Works with AT&T 5ESS and Northern Telecom DMS-100 switches that run either their custom protocols or National ISDN-1, as well as with other manufacturer's switches that use National ISDN-1 or National ISDN-2 call control signaling (ITU-T Q.931/I.451 call control signaling). Introduction 1-3 Link Diagnostics After each call, you can display a Link Diagnostics screen (ATI6) containing information about the last call, including the number of data characters transferred, line statistics, the call's rate, and the reason the call was disconnected. Switched-56 Support The I-modem can communicate to remote devices connected via Switched-56 circuits. V.120 and V.110 Connections V.120 and V.110 are standards for passing asynchronous data over ISDN B-channels, which are inherently synchronous. To make a connection using V.120 or V.110, devices at both ends of the connection must support V.120 or V.110. Modem and Fax Calls The I-modem emulates an analog fax/modem, allowing you to connect to remote analog modems and fax machines using 3.1 kHz audio format. Voice Calls If your I-modem has an Analog Device port, you can connect a standard, analog telephone and use the phone over your ISDN line. Be aware that the internal I-modem cannot provide ringing voltage through the Analog Device port, so equipment that autoanswers, such as a fax or answering machine, will not work correctly. Integral V.Everything Modem Features Supports Analog Fax/Modem Calls The I-modem always makes and receives calls over ISDN. Since there is no guarantee that the device at the other end of the line is ISDN-capable, the I-modem can communicate with non-ISDN devices, such as analog modems and Group III fax. 1-4 Courier I-modem Getting Started Guide x2 56-kbps Connectivity If you have enabled x2, your Courier can connect at speeds up to 56 kbps. While line conditions may not always allow for 56 kbps connections, the new Courier software allows you to achieve the fastest analog speeds available. Adaptive Speed Leveling to Adjust to Line Conditions Adaptive Speed Leveling® (ASL) allows your Courier to monitor line conditions while connected, and fall back to the next lower speed if conditions are poor. Couriers also detect improved line conditions and shift upward to the next higher speed. The transmit and receive channels adapt independently, each detecting and adjusting to line conditions. Calls to and from Modems and Fax Machines When used with fax-capable communications software, your Courier auto-detects and responds to calls from modems and Group III fax machines using EIA-standard Class 1 or 2.0 fax software. Data CompressionV.42 bis/MNP5 Data compression enables throughput of up to 230.4 kbps on analog connections. I-modems connecting under V.42 or HST error control use V.42bis compression. I-modems connecting under MNP error control use MNP Level 5 compression. Typically, files can be compressed from 2:1 to 4:1. Error ControlV.42/MNP Data integrity is ensured when the I-modem connects with remote devices that use the V.42 (LAPM), HST, or MNP error control protocols. Error control is available on analog calls at 1200 bps and above. V.Everything The Courier provides full support of the x2, V.34 standard, V.Fast Class, V.32 terbo, and many other modulation schemes, spanning the range of speeds between 300 bps and 56 kbps. Introduction 1-5 1-6 Courier I-modem Getting Started Guide Chapter 2 The I-modem and ISDN The Courier I-modem with ISDN/V.Everything is an Integrated Services Digital Network (ISDN) terminal adapter that can perform all the functions of a Courier V.Everything fax/modem. Overview The I-modem is capable of exchanging data over the ISDN at speeds of up to 128 kbps with ISDN devices or up to 56 kbps with analog devices, before compression. Internal I-modem There are two versions of the internal I-modem: · · The ISDN U-Interface with an analog device jack (Model U) The ISDN S/T-Interface (Model S/T) External I-modem There are two versions of the external I-modem: · · The ISDN U-Interface with an analog device jack (Model U) The ISDN S/T-Interface (Model S/T) External I-modem for Macintosh There is one version of the I-modem for Macintosh. The Courier I-modem for Macintosh is the same as Model U (ISDN U-Interface with Analog Device Jack). The I-modem and ISDN 2-1 What is ISDN? Integrated Services Digital Network is an application of digital technology that provides end-to-end digital service over the public communications network. ISDN was designed to integrate the transmissions from a variety of devices, (computers, telephones, and fax machines) into one digital network. Because ISDN was designed for transmitting digital information, it has many advantages over the analog telephone network. Digital transmission is more accurate and reliable, and that helps increase transmission speeds to up to 64 kbps per channel. Benefits of ISDN The benefits of ISDN include: · · · Increased bandwidth Fewer errors during data transfer Quicker call setups and teardowns. The ISDN Basic Rate Interface Physical Appearance The I-modem communicates over an ISDN Basic Rate Interface (BRI) line. You must order a BRI line from your local telephone company before you can use your I-modem. Chapter 2, Ordering ISDN Service, explains how to order ISDN and which services to request. BRI works over the same wiring that is in place for your analog telephone lines. The difference is in the equipment you attach and the signaling used. RJ45 Connector RJ45 Jack RJ11 Connector RJ11 Jack Figure 2.4 RJ45 and RJ11 Connectors and Jacks. 2-2 Courier I-modem Getting Started Guide At your site, the BRI line takes the form of an RJ45 or RJ11 wall jack, which in ISDN is called the U interface. RJ45 connectors have eight pins and RJ11s have four or six pins. At the U-interface, you can plug an RJ11 connector into an RJ45 jack, and your line will work correctly. The telephone company adds a line termination device at their end of the BRI that adapts the line for ISDN. B-channels and D-channels Though BRI signals are transmitted over an ordinary pair of wires, BRI typically contains three channels. The channels are created by complex signaling techniques. BRI is composed of two 64-kbps B-channels and one 16-kbps D-channel: This B-channels D-channel Does this Carries (or "Bears") data or voice traffic Sets up and tears down calls Logical View D-channel (16 Kbps) B-channel (64 Kbps) B-channel (64 Kbps) Physical View RJ45 Connector Figure 2.5 ISDN BRI--Three Logical Channels Over One Pair of Wires. The I-modem and ISDN 2-3 Required Components BRI-line signals must be translated into signals your computer can understand. Several devices must be in place to perform the translation. This TE2 (Terminal Equipment 2) TA (Terminal Adapter) NT-1 (Network Termination [Unit] -1 Is a device That does not have built-in ISDN capability. TE2s require Terminal Adapters (TAs), such as the I-modem, to communicate over the ISDN. Example: Computer. That translates between non-ISDN signaling that TE2s provide (such as EIA-232) and the S/T-interface signaling that the NT-1 understands. That ranslates between the short-distance signaling used at the S/T-interface and the longer-distance signaling used at the U-interface. NT-1s also convert from the two wires used for the phone line to the six or eight wires needed for the S/T bus. How Does the I-modem Fit In? The I-modem needs an NT-1 device to work with ISDN. If you currently use an NT-1 device, you can use the S/T-interface I-modem. This version of I-modem U-Interface Integrated NT-1 S/T-Interface Allows the I-modem to connect Directly to the U-interface To an external NT-1 device (you must have an NT-1 device) 2-4 Courier I-modem Getting Started Guide U-Interface with Integrated NT-1 Figure 1­5 illustrates how the I-modems with Integrated NT-1 connect your computer to the ISDN. BRI Line ISDN I-modem U Figure 2.6 A Typical Installation of the I-modem Once you've subscribed to ISDN service (see Chapter 2, Ordering ISDN Service, for much more detail), your local telephone company will install a BRI line at your site. You install the I-modem in your computer and connect a cable between the I-modem and the phone jack. Then run the I-modem Configuration Manager or send commands to change a few settings. Before long, you'll be making calls on the ISDN. S/T Interface Figure 2.6 illustrates how the I-modem S/T connects your computer to the ISDN. Note: Some NT-1s contain an integrated power supply. Power NT-1 Supply AC Power BRI ISDN U U + Power S/T I-modem Figure 2.7 A Typical Installation of the I-modem S/T. The I-modem and ISDN 2-5 Setting Up Your I-modem for ISDN You can get your ISDN service working by following these five easy steps: Step One: Subscribe to ISDN service. Step Two: Your local telephone company will install a BRI line at your site. Step Three: Install the I-modem in your computer. Step Four: Purchase and install an NT-1 (if necessary) and connect the cables. Step Five: Run the I-modem Configuration Manager and change a few settings. How the I-modem Calls a Variety of Devices When you use the I-modem, all your calls go over one or both ISDN B-channels. However, you can set the I-modem to make different kinds of calls over the B-channel: Internet Access (TurboPPP) TurboPPP makes the most of your ISDN line in a way that's transparent to your computer and the networking applications running on it. You can use TurboPPP to access the Internet or remote local-area networks (LANs) at speeds of up to 128 Kbps before compression and up to 512 Kbps with compression. TurboPPP is U.S. Robotics' unique combination of asynchronous-to-synchronous PPP conversion, compression, multilink PPP (MP-PPP), and PPP/MP-PPP spoofing. Asynchronous-to-Synchronous PPP Conversion Most Internet service providers that allow ISDN connections expect your data to arrive in synchronous Point-to-Point Protocol (PPP) format. Most computers, however, can't deliver synchronous PPP through their serial ports. To solve this problem, the I-modem has the ability to convert asynchronous PPP data to synchronous PPP. This capability allows you to use networking software that is intended for asynchronous PPP connections (such as Windows 95 Dial-Up Networking or NetManage Chameleon) to access the Internet or remote LANs. 2-6 Courier I-modem Getting Started Guide Compression The I-modem supports the leading de-facto standards for compression over ISDN: Stac LZS, Microsoft, and Ascend. Multilink PPP (MP-PPP) Multilink PPP support enables the I-modem to use both of the available B-channels simultaneously. The I-modem uses PPP/MP-PPP spoofing to mediate between applications running on your computer, which may not be aware of MP-PPP, and host computers that support MP-PPP. In effect, the I-modem tricks both ends of the connection, keeping them happy communicating the way they're accustomed, while maximizing throughput. Universal Connect When the I-modem is set to Universal Connect, it autosenses V.120, V.110, or analog fax/modem connections. Use Universal Connect when calling ISDN or analog Bulletin Board Systems (BBSs), for example. For details, see Chapter 11, Handshaking, Error Control, Data Compression, and Throughput, in the I-modem Command Reference manual. V.110 Connections V.120 and V.110 are standards for passing asynchronous data over ISDN B-channels, which are inherently synchronous. To make a connection using V.120 or V.110, the device at the other end of the connection must also support V.120 or V.110. A typical application of V.120 is for BBSs. Modem and Fax Calls The I-modem emulates an analog fax/modem, allowing you to connect to remote analog modems and fax machines. Clear-Channel Synchronous Connections When you set the I-modem to make clear-channel synchronous connections, it sets up a 64 Kbps connection with a remote device, enabling you to exchange any kind of synchronous data. Common applications of clear-channel synchronous are videoconferencing and remote access to mini- or mainframe computers. The I-modem and ISDN 2-7 2-8 Courier I-modem Getting Started Guide Chapter 3 Ordering ISDN Service This chapter gives you and your local telephone company all the information needed to set up the lines correctly. Overview To order ISDN service, contact your local telephone company, give them information about your I-modem, and record information that they give you, such as your new ISDN telephone numbers, called SPIDs. If you decide that you would like assistance with the ordering process, call the U. S. Robotics I-team at (888) USR-ISDN. The U.S. Robotics I-team The I-team is a subset of U.S. Robotics' Customer Support department that provides assistance with the ISDN ordering and configuring process. The I-team determines the availability and pricing of ISDN service in your area, installation costs, lead time for installation, and will coordinate the configuration of the telephone company's equipment so your I-modem will work properly. Ordering ISDN Service 3-1 Requesting ISDN Service 1 Call your local telephone company and request Bellcore Capability Package S (listed in Bellcore SR-3840). If your telephone company does not recognize Bellcore capability packages, request the following items: · · · ISDN BRI service. Number of channels: 2B+D, with no packet-mode data on the Dchannel. Call type support: This channel Data B-channel Analog Device B-channel Supports Circuit-Switched Voice and Data (CSV/D) Circuit-Switched Voice and Data (CSV/D) · · · · · Dynamic TEI assignment. Multipoint bus configuration. No features or special services such as CACH EKTS, call forwarding, or hunt groups. Terminal Type A.

The I-modem emulates a serial interface card with a 16550 UART. Like serial interface cards, it must be assigned a unique communications (COM) port number and a unique interrupt request (IRQ) number. If you are using a computer with a Plug and Play compliant BIOS and operating system and you set the I-modem's jumpers to Plug and Play (the default), your computer's operating system will take care of the COM and IRQ settings for you. Setting the COM port and IRQ yourself requires a detailed knowledge of the settings of the other adapter cards in your computer. If other adapter cards are set to use the same COM port or IRQ, conflicts may occur that could result in data loss or lockups. First, determine whether your computer has a Plug and Play ISA bus. Check your computer's documentation to be sure. Keep these points about Plug and Play in mind: · Your computer's operating system must support Plug and Play (examples of those that do: OS/2 Warp, Windows 95, Windows NT), or your computer's manufacturer must supply you with Plug and Play software. Your computer's Basic Input/Output System (BIOS) must support Plug and Play. · Installing the Internal I-modem 4-3 Installing Your Internal I-modem To install your internal I-modem, do the following: Step One: Configure your I-modem with jumpers (if necessary) Step Two: Configure your I-modem with DIPs (if necessary) Step Three: Insert your I-modem Step Four: Connect the cables Step One: Configuring with Jumpers Your I-modem comes configured for Plug and Play, which allows Windows 95 to automatically configure itself to work with the I-modem. Jumpers Figure 4.1 Jumpers Default Jumper Settings 4-4 Courier I-modem Getting Started Guide Figure 4.2 Default Jumper Settings In addition to the shunt shown in Figure 4.2, the I-modem is shipped with two additional shunts. These shunts do not affect the configuration of your I-modem because they are attached to only one post; change the positions of these shunts only if you need to change hardware settings. Notes: · · The S/T version has an additional set of jumpers. For most configurations, default settings will work. However, if your environment has multiple ISDN devices or you are using an NT-1, see the I-modem Command Reference manual. Windows 95 Users If you are using Window 95, you should not need to change the Plug and Play jumper settings, because Windows 95 automatically detects and configures your Courier. Other IBM-PC Compatible Operating Systems If you are using an IBM-PC compatible operating system, you may need to change the jumper settings to a COM port or IRQ setting that is not already used by your system. For information about setting jumpers for different COM ports and IRQ settings, see Chapter 12, Configuring Your Courier With DIP Switches and Jumpers. Installing the Internal I-modem 4-5 Step Two : Configuring with DIP Switches You will probably not need to change the DIP switch settings, but review this section to be sure. The DIP (Dual Inline Package) switches are located on the bracket of the I-modem. See Figure 3-7 to learn how to set the switches.

Note: The following AT commands are not changed by a power-on or reset and must be changed manually: &Cn, &Dn, En, Qn, Vn, S0=n, S14=n, and S67=n. If you change the DIP switch settings while the I-modem is on, you can avoid powering your computer off to make the new settings take effect. Just send the I-modem the ATZ or the ATZ! command. (ATZ! is a "hard" reset, which is just like powering the I-modem off and then on. ATZ is a "soft" reset, which is like rebooting the I-modem and not removing power.) Installing the Internal I-modem 4-7 Step Three: Inserting the Modem Note: The illustrations in this section may not match the appearance of your computer. For more detail, refer to your computer's user's manual. 1 Turn off the computer's power and unplug the computer's power cord.

If you cannot find a serial port, consult the documentation that came with your computer. 2 3 Connect one end of the phone cable to the wall jack and the other end to your Courier I-modem port labeled U. If you have Model U and a telephone that you'd like to connect to your Courier I-modem, plug its cable into your Courier port labeled PHONE. Plug one end of the power adapter into your Courier I-modem and the other end to a standard AC power outlet. Switch your computer and modem power on. 4 5 You are now ready to configure your Courier I-modem. 5-4 Courier I-modem Getting Started Guide Chapter 6 Using the Configuration Manager This chapter explains how to configure and test the I-modem using the Configuration Manager software. If the computer to which you've connected the I-modem cannot run Windows applications, follow the steps in Chapter 7, Configuring With AT Commands. Overview Configuration Manager The I-modem Configuration Manager is designed to help you make the ISDN settings to your I-modem and test whether you have a working connection with the central-office switch. Configuring the I-modem Before you can make any calls, you need to configure the I-modem to work on your ISDN line. If you haven't ordered an ISDN line, see Chapter 3, Ordering ISDN Service. Install and run the Windows Configuration Manager software shipped with the I-modem. The Configuration Manager runs on Windows 3.1, Windows 95, Windows NT, and Macintosh. What You Should Know Directory Numbers Directory Numbers (DNs) take the form of ordinary seven- or ten-digit telephone numbers. Be sure to leave off the area code from your DN. Using the Configuration Manager 6-1 Service Profile Identifiers Service Profile Identifiers (SPIDs) tell the telephone company about any special services and features to which you've subscribed. SPIDs can be up to 20 digits long. Terminal Endpoint Identifier The TEI is a one or two digit number that permanently identify a your connection with the central office switch.
