BPX 8600 Series

The BPX 8600 series provides a scalable set of solutions delivering ATM, Frame Relay, SNA, voice, and circuit emulation services, plus Voice Over IP, IP−based Virtual Private Networks (VPNs), managed intranets, and Internet services.

The BPX 8650 IP+ATM switch provides ATM−based broadband services, and supports MPLS to deliver IP services. The BPX 8680 Universal Service Node offers broadband, narrowband, and MPLS, and can be upgraded to OC−48c speeds.

The BPX 8600 series can be configured to support broadband, narrowband, and IP services, depending on specific needs. The switch supports the following interfaces: T3/E3 ATM, OC−3/STM−1, ATMOC−12/STM−4 ATM, T1/E1 ATM, n x T1/E1 IMA, Frame Relay, high−speed Frame Relay, SNA, circuit emulation, ATM UNI 3.0/3.1, and SMDS.

The switches also supports IP VPNs, Voice Over IP, managed intranets, premium Internet services, and IP Fax Relay.

The BPX 8600 series switch includes a 20Gbps crosspoint switching fabric in a 15−slot chassis. Three slots are reserved for common control modules, and 12 slots are provided for interface modules.

The broadband control card (BCC) is usually configured redundantly; it supports ATM cell switching, internal and remote−node communication, node synchronization, network−management communication, and shelf−management communication. The alarm status monitor card (ASM) monitors the power supply voltage and shelf temperature of the BPX 8600. The ASM card also includes telco−standard relays, which can activate switch alarm indicators. The switch also supports BXM cards that enable you to configure both PVCs and SVCs for ATM services.

The Cisco BPX 8600 series switch enables video on demand, IP Multicasting, distance learning, and videoconferencing. Multicast functionality ensures that latency−sensitive video traffic is delivered with the required bandwidth.

BPX 8680 Universal Service Node

The BPX 8680 Universal Service Node is a scalable IP+ATM WAN edge switch that combines the benefits of Cisco IOS IP with the extensive queuing, buffering, scalability, and QoS capabilities provided by the BPX 8600 series.

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.

This switch supports a Crosspoint Switch Fabric with a peak switching capacity of 19.2Gbps. It does this with twelve 800 or 1600Mbps switch ports that support up to OC−12/STM−4 cell rates. The arbiter establishes up to 20 million cell connections per second, making this a very fast WAN solution. This switch supports many WAN speeds including OC−12c/STM−4, OC−3c/STM−1, T3, E3, Channelized T3 (down to DS0), n x T1/E1, T1/E1, Channelized T1 (DS0 and DS0A), Channelized E1, HSSI, X.21, V.35, and LAN solutions including Ethernet, Fast Ethernet, and FDDI.
