Cisco MGX 8220 is a standards-based, integrated ATM edge concentrator that provides aggregation of a variety of services to a standard ATM User-Network Interface (UNI) or Network-to-Network Interface (NNI) port. The MGX 8220 edge concentrator can be used as an integrated or remote adjunct shelf for Cisco`s ATM switch product lines. In addition, it can serve as a standalone unit that aggregates traffic for transmission to and from an ATM network.
The Cisco MGX 8220 adapts incoming data to 53-byte ATM cells using industry-standard ATM Adaptation Layers (AAL) for transport over the ATM network. By integrating narrowband and broadband interfaces on a single platform, service providers can fully utilize the node capacity, incrementally expand capacity as needed, and cost-effectively provide services to an almost unlimited number of subscribers.
