Voicemail: E-mail: (847) 933-5200 sysdocs@usr.com Chapter 1 The Courier The Courier V.Everything Internal Modem makes any IBM-compatible computer with an Industry Standard Architecture (ISA) or Extended Industry Standard Architecture (EISA) expansion bus capable of exchanging data with modems or fax machines over standard, analog telephone lines at speeds of up to 33.6 Kbps. Using the Courier The most common uses of the Courier modem are accessing the Internet or online services, accessing corporate networks remotely, calling bulletin board systems (BBSs), and for sending or receiving facsimiles or files. Using the Courier always requires some kind of communications software. The software required differs depending on what you're trying to do. Accessing the Internet To access the Internet, you need to set up an account with an Internet service provider in your area. Often, Internet service providers supply you with the software you'll need. In other cases, support for Internet access is built in to your computer's operating system, as is the case with Windows 95. The software needed to access the Internet is called a TCP/IP protocol stack. Your TCP/IP protocol stack must provide a dialing application that is capable of sending data over a serial line using the Point-to-Point protocol (PPP) or the Serial Line Internet Protocol (SLIP). Introduction 1-1 Calling Online Services Each online service, such as America Online or CompuServe, provides its own customized communications software package. A couple of these packages are included with the Courier. These packages do the dialing and guide you through the steps of registration. Accessing Corporate Networks Remotely Dialing in to a remote network requires remote access software. When you dial in to a network, the software makes your remote computer appear to the network as locally attached. You can then use your network just as you would if you were there: send mail, print files, and access LAN drives. A remote access package is included with the Courier. Calling Bulletin Board Systems (BBSs) Calling a BBS requires communications software that does terminal emulation. The software should also support common, standard file transfer protocols, such as YMODEM and ZMODEM. A communications software package is included with the Courier. Sending Facsimiles or Files Most communications software packages support file transfers and many support fax operations. You can use fax-capable software to call fax machines or other fax modems and send facsimiles. 1-2 Courier V.Everything Internal Modems: Getting Started Courier Controls and Connectors This section shows the DIP switches and connectors on the Courier and indicates where to find more information about each.

The Courier 1-3 Features 33.6 Kbps Connectivity The Courier contains software that enables 31.2 and 33.6 Kbps connection rates, as well as improves throughput at lower speeds. While line conditions may not always allow for 33.6 Kbps connections, the new software makes it more likely that your Courier will achieve and maintain 28.8 Kbps connections. It can add up to 4800 bps to the average V.34 connection rate. Selective Reject Selective Reject is an optional part of the ITU V.42 (LAPM) specification. This feature improves performance on noisy lines by reducing the amount of overhead incurred when the protocol must resend data due to errors. When selective reject is active, only the frame that contained the error is resent, instead of the frame plus all of the following unacknowledged frames. You can disable selective reject by changing a setting in S-Register 51 (see Appendix A, Alphabetic Command Summary, in the Courier Modems Command Reference manual). Attaining Speeds Above 28.8 Kbps V.34 connections at 21.6, 24.0, and 26.4 Kbps are common. To get connections of 28.8, 31.2, and 33.6 Kbps, line quality must be pristine end-to-end. In addition, 31.2 and 33.6 Kbps connection rates are possible only when the device to which you are connecting also runs software that supports speeds above 28.8 Kbps. If you are curious about the role that line quality plays in attaining and maintaining high-speed connections, and want to learn what you can do to improve connections, request the following document from our Fax on Demand service: Phone Line Quality and High Speed Connections. The Fax on Demand number is (800) 762-6163. 1-4 Courier V.Everything Internal Modems: Getting Started V.Everything The Courier provides full support of the V.34 standard, V.Fast Class, V.32 terbo, and many other modulation schemes, spanning the range of speeds between 33.6 Kbps and 300 bps. We call this unique combination of abilities V.Everything. See the Compatibility section in Appendix B, Technical Specifications, for details. Flash ROM Upgradability Courier modems are software-upgradable using XMODEM file transfers, allowing you quick, easy access to updates of the Courier's technology. See Chapter 17, Upgrading the Courier's Software, in the Courier Modems Command Reference manual. Dial Security The Courier's dial security functionality is part of its operating software, which allows you to control access at a modem-tomodem 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 dialback. Refer to Chapter 9, Dial Security, in the Courier Modems Command Reference manual. Remote Configuration and Diagnostics You can remotely configure and test the Courier. If you are a network administrator supporting remote users, this feature can save you time and money. Refer to Chapter 8, Remote Access, in the Courier Modems Command Reference manual. Adaptive Speed Leveling (ASL) Couriers monitor line conditions while connected, and fall back to the next lower speed--for example, 19.2K, then 16.8K in V.32terbo mode--if conditions are poor. Couriers also detect improved line conditions and shift upward to the next higher speed. Transmit and receive channels adapt independently, each detecting and adjusting to line conditions. The Courier 1-5 Calls to and from Modems and Fax Machines When used with fax-capable communications software, the Courier auto-detects and responds to calls from modems and Group III fax machines using EIA-standard Class 1 or 2.0 fax software. Testing ITU-T V.54 loopback testing is available. The Courier can perform analog, digital, and remote digital loopback tests. See Chapter 15, Testing, in the Courier Modems Command Reference manual. Caller ID Support The Courier can interpret and display caller ID information. See the Caller ID section in Chapter 3, Dialing, Answering, and Hanging Up, in the Courier Modems Command Reference manual. Distinctive Ring Support The Courier can be set to recognize and respond to any of four distinctive ring patterns. See the Distinctive Ring section in Chapter 3, Dialing, Answering, and Hanging Up in the Courier Modems Command Reference manual. Carrier Loss Redial If you enable the carrier loss redial feature, the Courier will automatically redial the last number it dialed if carrier is lost (for example, if there is trouble on the line or if the remote modem hangs up). This feature is useful for dialed-line connections that operate unattended. See Chapter 3, Dialing, Answering, and Hanging Up, in the Courier Modems Command Reference manual. Plug and Play Support When you install the Courier in a computer that uses a Plug and Play operating system, such as Windows 95 or OS/2 Warp, the computer will automatically detect and configure itself to the support the Courier. 1-6 Courier V.Everything Internal Modems: Getting Started Dedicated- and Leased-Line Support The Courier does not need to be connected to the public switched telephone network. You can connect a standard telephone cable between the Courier and another modem and make connections without even dialing. You can also connect the Courier to a line that you lease from the telephone company. See Chapter 12, Dedicated/Leased Line and Synchronous Applications, in the Courier Modems Command Reference. The Courier 1-7 Chapter 2 Installing the Courier What You Need You must have these before you start: An IBM-Compatible Computer Your computer must have an ISA or EISA expansion bus and an available expansion slot. Check your computer's user's manual to be sure. An Analog Telephone Line The Courier requires a standard, analog telephone line. Do not connect the Courier to a digital telephone line! Digital lines are commonly used in office buildings and hotels. If you are unsure whether your line is analog or digital, ask a network administrator or your local telephone company. C ...
