2. Introduction and Description

2.1 Introduction

This User’s Manual will help you install, configure, test and use your Mini-Modem (56 kbps Data/Fax Modem).

2.2 Product Description

Your Mini-Modem incorporates a modem technology called K56flex™ that enables Internet connections at data rates up to 56 kbps over standard telephone lines. (In the United States, FCC regulations limit transmission speed to 53 kbps.) K56flex technology is able to propel data downstream from the Internet to your computer at speeds of up to 56 kbps because data is digitally encoded instead of modulated. Upstream transmission, mostly keystroke and mouse commands from your computer to the central site, continues to flow at the conventional data rate of 33.6 kbps.

Your Mini-Modem offers interactive automatic dialing, as well as command mode option configuration. You may store four command lines or telephone numbers, of up to 40 characters each, in the modem’s nonvolatile memory. The modem pulse or tone-dials, and recog-

MINI-MODEM (56 KBPS DATA/FAX MODEM)

nizes dial tones and busy signals for reliable call-progress detection. The modem can detect AT&T calling card tones. It is FCC-Registered for connection to telephone networks without any Data Access Arrangements (DAAs).

NOTE

Though this modem is capable of 56-kbps download performance, government regulations, line impairments, public telephone infrastructure, and other external technological factors currently prevent maximum 56-kbps connections.

The Mini-Modem is a desktop fax/modem for compatible IBM Personal Computers. It provides ial-up asynchronous communication capability with other personal computers, terminals, on-line computer services, or other types of computer systems.

Connection to the phone line and/or an attached telephone device is made by RJ-11 modular connectors; the PC connection is made via an RS-232C/V.24 serial cable receptacle; and low-voltage DC power is supplied to the Mini-Modem through a modular power-supply connection included with the modem. All these connections are located on the rear of the Mini-Modem. Hardware installation procedures are described in Chapter 3.

your Mini-Modem fax modem, you must contact your telephone company.

3.1.5 C

OMMUNICATIONSSOFTWARE

To operate the Mini-Modem, you must have data and fax communications software. Datacomm software simplifies control of the modem by guiding you through the process of selecting your serial port, your port speed, and other variables, and then storing your settings, including frequently called phone numbers, so they can be recalled with the stroke of a key or the click of a mouse. The software must be set up, or configured, before you can use it. You must have Microsoft Windows

3.1 or later to run most prevalent software packages.

3.1.6 A

SSEMBLE THEMODEM

The only assembly required is to mount the feet on the bottom of the modem. Simply peel the four self-adhesive plastic feet off the backing strip and press them into the recesses on the bottom of the modem. You can also use self-adhesive Velcro patches (not included) to mount the modem on a vertical surface or to keep it from being dislodged on a horizontal surface.

MINI-MODEM (56 KBPS DATA/FAX MODEM)

If you use Velcro patches, we recommend that you mount them where they will not obscure the labels on the bottom of the modem. The Mini-Modem has no special placement restrictions, but we recommend that you place it where you can see the indicators on the front panel.

If you have MS-DOS 5.0 or higher, a program called MSD.EXE [Microsoft Diagnostics] is in your DOS directory. Typing MSD at the DOS prompt brings up a screen that provides a variety of information about your computer.

Once you know your serial port’s UART type, you can set your communications’s software appropriately.)
