    that thread doesnt quite help me...

    however with regards to my routers I cant determine if it includes a NT1 built in....
    Because my BRI port has symbol underneath the port... which looks like a square with a cross inside it. Im reasonably sure I have read somewhere that a straight through cat5 cable is required if Iwant to connect two routers directly via the BRI ports (2x 2503 cisco routers)
    Im a newbie.... please be easy on me.

    I am not sure of the answer in this case but in every other case I can think of, if you are connecting two like devices it is a cross over cable that you need.

    In your case you have s/t interfaces. You will never get them to talk. You need a third router with NT1 interfaces or an ISDN simulator. I haven't seen it work with plain NT1 interfaces they were actually voice bri ports.

    oh right.. icon_confused.gif

    okay.. I wanted to ask a question.. Seeing I wont be able to setup a communication based on this information, supposing I went ahead and configured the BRI0 interface with all the stuff that is required to setup ISDN as per SybexCCNA pg 526->528, I cant seem to ping the local BRI0 interface.

    I should be able to ping that local interface correct? or no? ......
