Cisco MGX 8220 System Overview
The Cisco MGX 8220 Edge Concentrator is a standards-based, carrier-class concentrator that
concentrates high volumes of traffic for transport over Frame Relay and ATM backbones. The Cisco
MGX 8220 adapts incoming data to 53-byte ATM cells using industry-standard ATM adaptation layers
(AALS) for transport over the ATM network. A fully-redundant bus architecture provides 640-Mbps
capacity for high throughput and application performance.
