Voice/WAN interface cards (VWICs) can support voice, data, and voice and data applications, depending on the capabilities of the router in which the VWIC is installed.. The WIC is supported by many Cisco devices, particularly their branch routers including the 2500 series routers and its successors.
So this means that if we have a line card with WAN PHY then we can use G.709 optical SFP/XFPs with FEC, and with LAN PHY we don't have features like loss of signal, framing errors etc? That is not entirely correct. There is LAN, WAN and G709 encapsulations. WAN and G709 are not the same.
