Cisco Integrated Services Routers (ISRS) can be equipped with the Cisco Gigabit Ethernet Dual-Identity Enhanced High-Speed WAN Interface Card (EHWIC) which brings both Small Form-Factor Pluggable (SFP) and copper (RJ-45) Gigabit Ethernet connectivity. With the EHWIC cards, your Cisco ISRS can deliver accelerated applications such as Ethernet WAN access, inter-VLAN routing (IVR), and high-speed connectivity to LAN switches.
