Hey everyone, I finally got my stuff in a few days ago. I want to set everything up and start studying but I am slightly confused how the heck this all gets set up. The company i bought the stuff off of gave me a cable that I assume is used to connect the routers to simulate a WAN...although I am not 100% sure....
the two cables on top are the V.35 DTE & DCE M-F cables....the black cable on the bottom left is the same type connection that I believe i can use instead of the ones on top. I put the 1,2, and 3's where i thought the connections should be. Is this right?

I also got two of these little guys which I am unsure exactly what they do. Are they optional or are they a vital part of setting everything up? I did some searching but I could not find anything that explained them good enough. Its seems they indicate traffic flow and convert rj45 to serial


Ok now after a long winded post thank you for any help anyone can offer me. This is my first time ever setting up equipment like this...thanks!
