The Cisco Gigabit Ethernet dual-identity Enhanced High-speed WAN Interface Card (EHWIC) brings both Small Form-factor Pluggable (SFP) & copper (RJ-45) Gigabit Ethernet connectivity to Cisco Integrated Services Routers (ISRs) to accelerate applications such as Ethernet WAN access, inter-VLAN routing (IVR), & high speed connectivity to LAN switches. The single-port Cisco Gigabit Ethernet EHWIC provides Gigabit Ethernet optical & copper connectivity in a compact form factor to the Cisco Integrated Service Router Generation 2 (ISR G2). The Gigabit Ethernet EHWIC enables branch offices to cost-effectively use high-speed uplinks in numerous environments. The enhanced performance of Gigabit Ethernet in Cisco ISR G2 routers enables applications & services & provides greater capacity for existing IVR & bridging capabilities. Branch offices can connect to Ethernet WAN (EWAN) Layer 2 & 3 services.
