Chapter 1 - Introduction

1.1 Introduction

Welcome to the world of data communications. You have acquired one of

the finest intelligent data/fax modems available today, either the model

MT2834BR or MT2834BLR (MT2834), from Multi-Tech Systems. Your

MT2834 modem provides data communication at 33,600-14,400 bps

(*Enhanced V.34/V.32bis), as well as other prevalent datacomm standards.

The MT2834 also includes adaptive protocol enhancing used in typical

Unix® batch file transfers and support for IBM's AS/400 (iSeries)TM and

System3xTM environment. The MT2834BLR provides support for dial back-

up with automatic leased line restoral. This User Guide will help you install,

configure, test and use your MT2834 data/fax modem.

*Note enhancements on V.34 code (33.6K/31.2K) is awaiting formal ITU

approval; the ITU study group 14 has agreed on the technical side of the

proposal, with formal approval expected at the next ITU meeting in

Geneva.

1.2 Features

The MT2834 automatically adjusts to line conditions and the capabilities of

the modem it connects to, resulting in the highest possible speed, the most

accurate error correction, and the most efficient data compression possible

for each connection. The MT2834 is designed for data rates as high as

33,600 bps in full-duplex mode over public telephone lines.

MT2834 features include:

· Support of data rates of 33,600, 31,200, 28,800, 26,400, 24,000, 21,600,

19,200, 16,800, 14,400, 12,000, 9600, 7200, 4800, 2400, 1200, 0-300

bps.

· Automatic fallback to slower speeds in noisy line conditions, and fall-

forward to faster speeds as conditions improve.

· ITU-T V.42 LAP-M and MNP Classes 3 and 4 error correction.

· Data transfer rates up to 115,200 bps with V.42bis 4-to-1 data

compression.

· Automatic disabling of compression when transferring already-

compressed files.

· Serial port data rates adjustable to 115.2K bps.

· Autodial, redial, pulse (rotary) and touch-tone dial.

· Dial tone and busy signal detection for reliable call-progress detection.

· Compatibility with the standard AT command set used by most

communication programs.

· On-screen help menus.

· Nonvolatile memory for storage of customized modem parameters and

ten telephone numbers.

· Sends and receives faxes from your computer at 14,400, 9600, 7200 or

4800 bps.

· Responds to EIA TR.29 Class 2 fax commands.

· Supports UNIX-to-UNIX® UUCP Spoofing.

· Supports IBM's AS/400 (iSeries)TM and System3x environment.

1.3 How to Use This Manual

This chapter begins with a short introduction, a profile on modem features,

followed by a guide (which you are now reading) to the use of this manual.

This manual includes hardware installation and configuration described in

Chapter 2. Chapter 3 covers communication software configuration

recommended for the MT2834. Other issues covered include setting up

initialization strings, changing default parameters, configuring software for

the remote system and file transfer protocols. Chapter 4 covers modem AT

commands, Remote Configuration commands, S-Registers and Result

Codes. Chapter 5 illustrates the MT2834 diagnostic capabilities, providing

Analog and Digital Loopback testing procedures. Chapter 6 explains

product warranty and technical support. Appendices A and B respectively

describes FCC requirements and regulations and technical specifications.

Chapter 2 - Installation

2.1 Preliminaries

This chapter covers MT2834 installation and connection. In addition to the

contents of the MT2834 package, you will need the equipment listed

below.

2.1.1 Card Cage

The MT2834 is designed to mount in the Multi-Tech Systems' modem rack

(see Section 2.2 for various models available). This rack is an EIA-

standard 19-inch wide by 7-inch high rack, and mounts in any standard

computer cabinet. The rack has a sixteen modem slot capacity, one power

supply source (the CC1600 series card cage has a redundant power

supply capability), sixteen 25-pin (female) connectors for RS232C/V.24

interface and sixteen DB9 (female) connectors for phone line (the CC1600

series card cage has RJ11 back-plane connectors for phone line interface).

2.1.2 Serial Cable

You must provide a serial cable to connect each corresponding MT2834 to

your computer. The cable must have a DB-25 male interface into the

modem rack.

2.1.3 Telephone Line

The MT2834 uses one RJ11 jack per corresponding modem slot to

connect to the telephone lines. To connect the modem to the phone lines,

plug one end of the RJ11 cable that is provided with the modem into the

DB9 (9-pin connector) located on the back plane of the modem rack and

the other end into the phone-company-provided RJ11 or RJ11W modular

phone jack (CC916, CC1416 or CC2816 racks). To connect the modem to

the phone lines using the CC1600 modem rack, plug one end of the RJ11

cable provided with the modem into the rack's RJ11 connector (located on

the back plane of the modem rack) and the other end into the phone-

company-provided RJ11 or RJ11W modular phone jack.

Chapter 2 - Installation

2.2 Installation

Perform the following procedure to install modem cards in the CC916,

CC1416, CC2816 or CC1600 racks*. The installation process involves:

1. Power cord must be unplugged prior to installation of the Power

Source(s). Insert Power Source(s) (PS216A or PS1600) into far right of

the rack cage.

2. Slide a modem card into one of sixteen available modem slots. Start by

inserting a modem into the left-most channel (slot #1) of the rack. The

toggle switch should be at the bottom of the card, with the component

side of the card facing the right. The modem’s gold edge connector is

offset so that the modem cannot be inserted incorrectly. Continue

installing modem cards as necessary.

3. Plug RS232C Cable into appropriate modem slot (DB25/25-pin

connector-female) at rear of rack. Note: Any cables connected to the

computer must be shielded to reduce interference.

4. If you are connecting your phone line directly to the modem card, plug

the phone line cable into the appropriate modem slot (DB9/9-pin

connector-female) at the rear of the rack and the other end into the

phone-company-provided RJ11 or RJ11W modular phone jack. To

connect the modem to the phone lines using an CC1600 modem rack,

plug one end of the RJ11 cable provided with the modem into the rack's

RJ11 connector (located on the back plane of the modem rack) and the

other end into the phone-company-provided RJ11 or RJ11W modular

phone jack.

5. Plug in modem rack power cord.

6. Verify remote modem's current configuration settings with your

MT2834BR in terms of data compression, error correction, transmission

rate, etc. (ATL5/ATL7 Command - see Chapter 4 on AT commands).

7. Attach MT2834BR to dial-up phone lines and/or leased lines and verify

DIP-Switch #10 and #5 settings (Section 2.5).

8. Make sure modem and computer/terminal serial port baud rates are

adjusted (Section 2.5.).
