Some of you may still remember my earlier post about whether buy CISCO devices for CCIE certificate... Well, I have decided to buy some real devices instead of only using the simulator (GNS3) as 3 virtual 2620 routers are enough to crush my weak computer... Thank you guys for your kind suggestions! They helped a lot!
Now I have another problem... When I am searching on ebay, I see two types of WIC cards for T1: WIC-1T/2T and WIC-1DSU-T1. I know that the first one is recommended but I just want to know what the second one is for and whether I can use the second card for Frame-Relay lab? This card also has version 2 like WIC-1DSU-T1-V2, do I need it just for lab learning?
Half of the 2600s on ebay has the second type of WIC. Half of the routers don't ship to Canada. Now you know why I don't want to ignore them...
