    If I add a WIC-1DSU-T1 WIC T1 to a 2650 router and another to a 3620 router
    can I pin a cable to make a dte/dce connection to simulate a wan?

  2. Yes. Google on 'Cross-over T1 cable'. There'll be a ton of hits.

    You are beyond having a DTE or DCE once you have it encoded up to T1,
    but having a point-to-point T1 that is 6" long works exactly just the
    same as having a real telco circuit.

    Thank you, do you know if these are the right WIC's to do this with?

  4. Yes, they'll work fine in both those routers.
    Only problem with that one is that the counterfitters made so many bad
    copies.. :)

    Okay, thanks, sorry to ask again, Ebay is not real forgiving when buying the
    right thing.

    I just bought two to simulate my wan connection to do QoS with it. Hope I
    got the real stuff.

    If you bought them on E-Bay, chances are about 95% that they are

    You will need to make or acquire a cross-over T1 cable. This is NOT the
    same as a crossover Ethernet cable. You will need to learn all about T1
    clocking. On one side you will need to configure it to provide clock, and
    the other side to recover clock.

    I actually did this before with a old pair of 2600 with t1 cards but being
    Cisco makes so many different modules I don't remember what they were, every
    hand off I have now is ethernet and is a lost art to me. I cant remember
    what I used, know there is a wic you cant do this with, and I think the pins
    I use in the cable were

    1 - 3
    2 - 6
    3 - 1
    6 - 2

    Some old Bell telecomm tech gave me the pin outs and was for an interal lab
    we built to replicate our lan/wan topology for the great NT 4.0 to W2K3 AD

    Again thanks everyone, I got the pinouts wrong it is actually

    The wiring is:

    1 - 4
    2 - 5
    4 - 1
    5 - 2
