Introduction

The Patton DialFire Model 2977 family of DSP-based RAS concentrator adapters are designed for such server- based applications as modem-pooling, remote access, advanced fax, World-Wide Web and branch office inter- networking.

The dense modem technology built into DialFire adapters is based on high performance digital signal proces- sors (DSPs). On-board DSPs provide advanced modem and fax support and maximize the efficiency of each communications channel. Each DialFire channel operates independently and configures itself dynamically for analog (up to V.90 or K56flex) or digital (ISDN B-channel) support. This ensures smooth, remote connections regardless of whether callers are using analog modems or ISDN devices.

All DialFire adapers operate within the PCI 2.1 mechanical and electrical specifications, support 3.3-or 5-volt PCI and CompactPCI servers, and share a common software architecture. These features ensure compatibility with a wide variety of PCs and application software, enhance reliability, and facilitate support.

DialFire adapters integrate with the inherent communication capabilities already built into your server operat- ing environment. DialFire drivers are written to standard APIs and are enhanced with PattonAssist manage- ment software. Using standard APIs ensures that installing and managing your ports will already be a familiar and intuitive process for network administrators. IT managers can continue to use the same management sys- tems and administrative tools they know and trust. Users can continue to use the same remote access resources they're accustomed to since the DialFire RAS concentrators offer full modem coverage.
