... just to know if I have to send that router (I got a few days before) to garbage or if I have a chance to use it for a better scenario:
The 1603 have a WIC slot, but I am not sure if I can use an Single Ethernet WIC card. I have an ISDN WIC card already, but it would appreciate it much more to have a LAN port. If not -> garbage, because ISDN isn't my favorite WAN access method.
