Section 1 System Description ATLAS 550 System Manual

1. SYSTEM OVERVIEW

The ATLAS 550 is a modular, highly scalable platform that provides robust solutions for the wide-area communication needs of small-to-medium corporations and network access providers. The ATLAS an Integrated Access System with extensive support of dedicated bandwidth management and access switching. It contains a high-performance CPU and powerful communications drivers which support applications such as frame relay, dial-backup, and PPP (point-to-point protocol).

The ATLAS 550 architecture also includes a packet and circuit switching bussing scheme. The result is a system capable of supporting bandwidth requirements of up to nine T1 circuits or five Primary Rate ISDN (PRI) circuits. Designed for standalone, rackmount, or wallmount installations, the ATLAS 550 base unit provides two hot-swappable network interfaces and four expansion slots that accommodate hot-swappable option modules for a variety of applications. A 10/100BaseT Ethernet connection for IP routing and network management is standard with the ATLAS

With the ATLAS 550, you can consolidate voice, data, and video applications into a single platform while optimizing wide area bandwidth and reducing equipment costs. The ATLAS expansion slots accept a variety of modules, making it one of the most versatile access systems on the market.
