Adtran ATLAS 550 Data Networking Model Overview
The Adtran ATLAS 550 of Integrated Access Devices (IADs) offers one of the most versatile integrated access platforms available on the market today for converging voice, video, data, and Internet communications. This series includes the ATLAS 550 Integrated Access Device (IAD) chassis, modules, and bundled systems designed to improve and lower network costs for enterprise businesses and network service providers.
Adtran 1200550L2 Data Networking Overview
The ATLAS 550 is an Integrated Access Device (IAD) designed to improve and lower the costs of voice/data, video, and Internet communications for enterprise businesses and network service providers. With the ATLAS 550, many WAN functions have been combined into a small, economical, modular platform that will replace a rack of traditional single-function access devices. With the ATLAS 550, traditional multiplexed and packet networks are easier to deploy and manage, while providing more bandwidth efficiency out of new or existing communications links. The ATLAS 550 provides a new level of communication flexibility by offering many of the features previously found in larger central office, PBX, or router equipment.

The ATLAS 550 chassis includes a high-speed multi-protocol backplane and six modular expansion slots: two network interface slots and four user interfaces slots. A wide range of hot swappable, industry standard modules are also available to effectively converge telecommunications and existing network systems such as routers, PBX, key systems, video conferencing equipment, remote access servers, LANs, faxes, and telephones. The ATLAS 550 typically resides at the customer site and performs the functionsfound in multi-port multiplexers, channel banks, 1/0 cross connect switches, Frame Relay Access Devices/concentrators/switches, IP routers, and ISDN switches. It also includes an integral voice switchboard and dial plan for dynamically and intelligently switching voice and data calls based on the telephone number dialed.
