ISDN simulators

Hi all,

after reading some stuff on CCNP home labs I came across 'ISDN simulators'.

I understand that these devices emulate a phone line on which you can actually place calls and stuff which will go out on a second channel of the simulator.

After seeing the prices of those boxes I wonder if it wouldn't be sufficient to buy a very small telephone system (like 4 port ISDN) with an internal bus. One should then be able to place internal calls and connect routers together this way or am I missing something here ??

Regards,
Lordy

    the $600 one is the one i have. it works fine.
    i broke down and bought it.

    the company that makes it is located in england

    it would be hard to put it togther on your own.
    you'd have to have a good working knowledge of isdn/bri.
    signaling, spids ... etc.

    these are good if your on a budget and dont want to fork out $600! I have a similar model and it does most things execpt SPID

    Even though it will emulate ISDN traffic... but spids is what is important in the NPs studies. Unless of course, Ive been studying the wrong stuff! icon_sad.gif

    Most ISDN in the UK and Europe don't use SPIDs if I remember correctly. I believe that's pretty much a US thing for the last few years anyway. I did a bunch of ISDN work on US and UK circuits a few years ago (kind of dying out now) and knowledge of SPIDs is a very small portion of understanding ISDN. If you want to really play in the ISDN world, you need to figure out call set up and tear down. A lot of this goes above the the remote access exam level if I remember correctly, but to do it for real you need to understand it.

    Course you won't find many job opportunities for an ISDN engineer :P

    wonder if prices of ISDN sims will go down with ISDN being pulled from the CCIE Lab?

    If you do a search on eBay for vconsole, you will get a listing for a CCIE that is selling the new 2 port simulators for $595.

    Yes it does hurt but it is less than MSRP and he is very helpful. If you have any doubts on it, check the feedback I left him as kcdavis2. Mine arrived the next afternoon and he gave me his phone number and direct email if I had any questions.

    Just trying to help. I know how expensive it is. My last 2 routers arrived today for a total of 12.
