COURIER HIGH SPEED MODEMS

CHAPTER 1. FEATURES AND COMPATIBILITY

INTRODUCTION

Congratulations! The Courier modem you've purchased repre- sents powerful, advanced electronic design that offers excep- tional reliability, compatibility and flexibility at all standard rates up to 28,800 or 28.8K bits per second (bps). The transmission rate between the computer and modem, depending on your equipment and software support, can be as high as 115.2K bps.

Features

The following features and capabilities assure you of superior reliability and performance.

Connections up to 28.8K bps

With the V.34 standard and the V.Fast Class modulation scheme, two modems can connect at rates up to 28.8K bps, twice as fast as the rates of standard ITU-T (formerly CCITT) V.32 bis modems, which are limited to calls of 14.4K bps or less.

Software Upgrades

Courier high speed modems are now software upgradable, allowing you quick, easy access to the latest advances in data communication technology. See Appendix I.

Quick Connect

In V.32 terbo mode, Courier high speed modems can handshake and start transmitting much faster than typical training times that range between 9 and 18 seconds for other modems.
