I manage a small network. I have a Cisco 2600 router. The router currently has 2 one port WICs installed, each connected to a separate T1. We want to upgrade and the ISP told me that I need 2 two port WICs to handle the 4 T1s.
Online, I found the Cisco 2-Port Serial WAN Interface Card (WIC-2T). The WIC-2T has serial ports instead of the Ethernet port that my single WICs have. How will I plug the new 2 port WICs into the ethernet ports of the ISPs equipment?
