About the AccelePort RAS 4/8 Adapters

Introduction

The AccelePort RAS adapters provide four or eight high-speed modems in a package that fits in a single PCI slot in your server. You can install multiple AccelePort adapters in a single server to add capability as system needs grow. The AccelePort RAS adapters enable server-based applications such as modem pooling, remote access services, and advanced fax services.

The AccelePort RAS adapters use dense modem technology based on industry-standard digital signal processors (DSPs). The software-upgradeable DSPs let each AccelePort channel operate independently at maximum efficiency, providing advanced modem and fax features.

All AccelePort models operate in 3.3- or 5-volt PCI servers and share a common software architecture. All Digi RAS products conform to the same API, allowing developers to write drivers for proprietary operating systems, or for standard operating systems with proprietary extensions. These features make AccelePort adapters compatible with a wide variety of PCs, operating systems, and application software.

Features

AccelePort RAS adapters include the following features:

• Four or eight RJ-11 ports (one for each on-board modem) mounted on the rear panel for telephone line connections
• Independent 56 Kbps analog modem operation (both K56flex and V.90) on each port, with advanced data and compression mode compatibility
• Independent fax operation on each port, with advanced fax mode and command set compatibility
• Unlimited AccelePort DSP-based adapters and DataFire DSP-based adapters can work together in the same server. Practical limitations depend on the capability of the server platform.
