PRODUCT OVERVIEW

The ATLAS 550 is a modular, highly scalable platform that provides robust solutions for the wide area communication needs of small-to-medium cor- porations and network access providers. ATLAS 550 is an Integrated Access System with the most extensive support of dedicated bandwidth manage- ment and access switching in the industry.

The ATLAS 550 is a lower bandwidth version of the ATLAS 800PLUS. The ATLAS 550 contains a high-performance CPU and powerful communications drivers which allow the support of optional applications such as frame relay.

The ATLAS 550 architecture also includes a packet switching and a circuit switching bussing scheme. The result is a system capable of supporting bandwidth requirements up to four T1/E1 or Primary Rate ISDN (PRI) cir- cuits. 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 modules for a variety of applications. A 10/100BaseT Ethernet connection for remote access and network management is standard with the ATLAS 550 Base Unit.

The ATLAS 550 modules include the following:

•Dual Nx 56/64 Option Module

•Dual T1/PRI Option Module

•Quad Basic Rate ISDN Option Module

•Octal/Quad FXS Option Module

•Octal/Quad FX0 Option Module

•Resource Host Module

•Voice Compress Resource Module

•T1 Network Interface Module

With the ATLAS 550, you can consolidate your voice, data, and video appli- cations into a single platform while optimizing wide area bandwidth and re- ducing equipment costs. The ATLAS 550 architecture and the chassis’ four expansion slots allow for a variety of modules, making it one of the most ver- satile access systems on the market. With the appropriate modules installed, the two main functions of the ATLAS 550 are to act as an Access Router and an Access Switch.
