Cisco Enhanced High-Speed WAN Interface Card EHWIC-1GE-SFP-CU

The Cisco® Gigabit Ethernet Dual-Identity Enhanced High-Speed WAN Interface Card (EHWIC) brings both Small Form-Factor Pluggable (SFP) and copper (RJ-45) Gigabit Ethernet connectivity to Cisco Integrated Services Routers (ISRs) to accelerate applications such as Ethernet WAN access, inter-VLAN routing (IVR), and high-speed connectivity to LAN switches. The Gigabit Ethernet EHWIC enables branch offices to cost-effectively use high-speed uplinks in numerous environments (Figure 1). The enhanced performance of Gigabit Ethernet in Cisco ISR G2 routers enables new applications and services and provides greater capacity for existing IVR and bridging capabilities. Branch offices can now connect to Ethernet WAN (EWAN) Layer 2 and 3 services.
