Introduction
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 800
PLUS
. 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 avariety
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
•DualT1/PRIOptionModule
•QuadBasicRateISDNOptionModule
•Octal/QuadFXSOptionModule
•Octal/QuadFX0OptionModule
• Resource Host Module
• Voice Compress Resource Module
•T1NetworkInterfaceModule
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.
