The Enhanced FlexWAN module is installed in a Catalyst 6500 series switch or Cisco 7600 series router that has a supervisor engine with a multilayer switch feature card (MSFC) and policy feature card (PFC). The MSFC, in conjunction with the Enhanced FlexWAN module, provides multiprotocol routing support with full Internet route connectivity for speeds ranging from serial RS-232 to OC-3. The Enhanced FlexWAN module can accept up to two Cisco7200/7500 WAN port adapters, which deliver WAN consolidation and extend quality of service (QoS) and traffic management capabilities over WAN segments. The Enhanced FlexWAN module supports ATM and POS OC-3 links and channelized, clear-channel port adapters at speeds from DS0 to T3/E3, and High-Speed Serial Interface (HSSI). Additionally, the Enhanced FlexWAN module provides connectivity to the crossbar fabric along with enhancements in processor speed and onboard memory.
