BPX 8680

The BPX 8680 universal service switch is a scalable IP+ATM WAN edge switch that combines the
benefits of Cisco IOS® IP with the extensive queuing, buffering, scalability, and quality-of-service
(QoS) capabilities provided by the BPX 8600 and MGX 8800 series platforms.
The BPX 8680 switch incorporates a modular, multishelf architecture that scales from small sites to
very large sites and enables service providers to meet the rapidly growing demand for IP applications
while cost-effectively delivering today's services.
The BPX 8680 consists of one or more MGX 8850s connected as feeders to a BPX 8620. Designed for
very large installations, the BPX 8680 can scale to 16,000 DS1s by adding up to 16 MGX 8850
concentrator shelves while still being managed as a single node.

BPX 8680-IP

The BPX 8680-IP scalable Layer 2/Layer 3 WAN solution integrating the proven multiservice
switching technology of the Cisco BPX 8650 switch with the flexibility and scalability of the Cisco
MGX 8850. The MGX 8850 switch serves as an edge concentrator to the BPX 8650, which employs
the BPX 8600 series switch modular, multishelf architecture to enable scalability. The BPX 8650 switch
includes a Cisco 7204 label switch controller (LSC) and supports multiprotocol label switching (MPLS)
for New World integrated infrastructures.
