Cisco BPX 8600 Series—Advanced ATM Multiservice Switches
The Cisco BPX 8600 series is an ATM switch with advanced IP and ATM capabilities.
Designed to meet the demanding, high-traffic needs of a public service provider or large
private enterprise, the BPX switch delivers high-performance ATM switching, multiservice
adaptation and aggregation for all types of user traffic. Proven in the world's largest ATM
and Frame Relay networks, the BPX 8600 enables service providers and large enterprises
to meet skyrocketing network demands.
The Cisco BPX 8600 series switch offers up to 20 Gbps of high-throughput switching for
multiple traffic types data, voice, and video and supports a wide range of interfaces, from
Frame Relay to full broadband subscriber interfaces, up to 622 Mbps with a connection to
an Edge Concentrator. You can offer multiple services for LAN, X.25, SNA, IP, Frame
Relay, and ATM traffic from a single BPX platform. The Cisco BPX 8600 series supports
multiprotocol label switching (MPLS).

Cisco MGX 8850 ATM Multiservice Switch
The Cisco MGX 8850 ATM Multiservice Switch enables delivery of a complete portfolio
of service offerings while scaling from DS0 to OC-48c/STM-16 speeds. It enables service
providers to be first to market with high-margin voice and data services while maintaining
existing services. The MGX 8850 universal chassis provides a unified ATM architecture
that delivers a complete portfolio of differentiated services —from circuit emulation to IP
VPNs—all with a single chassis, to enable service providers to easily add new services.
The Cisco MGX 8850 can function in three different modes of operation:
• PXM-1 configuration—Operates as a stand-alone device for narrowband services, or
as an integrated edge concentrator for the Cisco BPX 8600 series or the Cisco MGX
8850 PXM-45
• PXM-1E configuration-Operates as a stand alone switch for low density narrowband
services, it includes a 1.2 Gbps switch card and PNNI routing
• PXM-45 configuration—Serves as a broadband edge switch and includes the 45 Gbps
switch card and broadband ATM modules. The PXM-45 configuration also supports
standards-based PNNI routing.
