I-modem Features Dial Security to Control Access to Your System The Courier’s Dial Security feature allows you to control access at a modem-to-modem level instead of using software that runs on the host computer. 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.
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.
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.
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.

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.
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.
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.
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 Is a device TE2 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.
U-Interface with Integrated NT-1 Figure 1–5 illustrates how the I-modems with Integrated NT-1 connect your computer to the ISDN. BRI Line I-modem ISDN 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.
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.
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.

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.
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.
4 Obtain the following information from your local telephone company: • • • • 1 SPID (Service Profile Identifier) per B-channel. 1 DN (Directory Number) per B-channel. Call types supported on each B-channel. If the switch does not auto-assign TEIs (most do), then you need one fixed TEI per B-channel. For this Record the number here SPID 1 SPID 2 DN 1 DN 2 5 If you have an internal I-modem, continue with Chapter 4, Installing the Internal I-modem.

Chapter 4 Installing Your Internal I-modem This chapter explains how to: • • • • Configure with jumpers Configure with DIP switches Insert the internal I-modem Connect cables to the internal I-modem Important: Review Chapter 2, The I-modem and ISDN, and Chapter 3, Ordering ISDN Service, before installing the I-modem.
Package Contents Your I-modem package contains the following items: • • • • • • • 4-2 The I-modem Telephone cable Quick Reference card Customer Support card This Getting Started manual I-modem Configuration Manager diskette.
Important! 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.
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.
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.
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. DIP switches Figure 4.3 Location of the DIP Switches.

protocol, you can use fewer than two SPIDs/DNs, although this is not recommended. Lines with fewer than two SPIDs/DNs prevent your making two analog-based calls at one time. For example, with fewer than two SPIDs/DNs, you can make a digital call (such as V.120 or synchronous PPP) and a voice call at the same time, but not a fax/modem and a voice call simultaneously.
11 Incoming Modem/Fax Call Routing Select one of the following: To use The I-modem routes incoming analog calls Analog Device Port To the Analog Device port (handled by the device attached to the Analog Device port). Data Port To the Data Port (handled by the I-modem). 12 Bus Configuration Select Point-to-Point. If You Have One SPID and One DN Make these modifications when entering your line configuration. 2 Data Channel Service Profile ID Enter your SPID (up to 20 digits).
Chapter 7 Configuring With AT Commands This chapter explains how to configure and test the I-modem using AT commands and terminal software. Overview 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. Run your communications software in Terminal mode and then use your software to send the I-modem AT commands.
Preparing to Send AT Commands 1 Get the information from your ISDN service provider that contains your ISDN phone numbers and central-office switch type. 2 Start your computer and your communications software. Use a terminal emulation software package, such as HyperTerminal. 3 Put your communications software into Terminal mode. When your communications software is in Terminal mode, the commands you type go directly through the serial port to the I-modem.
Configuring and Testing Your I-modem Before you can use your Courier, you must perform the following steps. Step One: Configure the I-modem Step Two: Check the I-modem’s settings Step Three: Save the settings Step Four: Test the I-modem Step One: Configuring the I-modem 1 Look over the information you received from your ISDN service provider to obtain your central-office switch and protocol type.

Dynamic Data Bandwidth Allocation Dynamic Data Bandwidth Allocation is a cost savings feature that helps you save money by only using the second B-channel when it is need for data transfers, and then dropping the second B-channel when it is not needed. Dynamic Bandwidth Allocation determines the need for the second B-channel by measuring the amount of data sent or received during a set period of time.
Setting When the Second Link Comes Up Use the following *D3 setting to determine when the I-modem should bring up a second link: To do this Use this setting Example Determine when the second link should be brought up, based on the level of utilization of the existing link *D3=n, where n equals 1 -100% *D3=90 (90%) Setting When the Second Link Comes Down Use the following *D4 setting to determine when the I-modem should bring down a second link: To do this Use this setting Example Determine when the
Using Compression in TurboPPP mode Courier I-modem supports the following three types of compression modes in TurboPPP. Pass-through Compression Pass-through compression allows the terminal applications running on each PC on both ends of the connection to perform compression. Using this form of compression, the Courier I-modem does not perform compression. Pass-through compression allows for maximum compression by eliminating the serial port bottleneck.
I-modem supports a 230 kbps DTE rate using ML-PPP.

Appendix A Other I-modem Features This chapter explains how to use new features not covered in the Courier I-modem Command Reference manual. Data Over Voice Data Over Voice (DOV) is a feature that allows the I-modem to make more cost effective 3.1 kHz analog calls while allowing the I-modem to send digital data at 56 kbps. Note: DOV is becoming widely used due to the fact that Regional Bell Operating Companies usually charge less for analog calls than digital calls.
Period Dial Modifier The period (‘.’) dial modifier is used to send DTMF tones after the telephone number is dialed. The period dial modifier can be used with the comma (',') dial modifier to insert delay between the numbers as appropriate for the application. A typical application for the period dial modifier is use with PBX systems. Example: ATDT18479335200.980234 In this example, 18479335200 will be dialed using ISDN signaling, then 980234 will be dialed using in band DTMF signaling. PCSDL vs.
Saving Money With Analog Calls By default, the I-modem anticipates the rare occasion that telephone company equipment incorrectly allows a digital connection when you call a modem or fax machine. In these situations, although the I-modem proceeds with the call as a standard analog (fax or modem) call, the telephone company bills the call as digital. Digital and Analog Billing Structures Often the billing structure for digital (“data”) calls is different than for analog (“3.1 kHz audio”) calls.
