Is ISDN simulator recommended for Cisco certs?

I am in the process of studying for my CCNA and would like to know if ISDN is covered in any great detail on the exam? I don't want to shell out $600 for a simulator that I don't need or study a topic that is no longer relevant.

I suggest spending that on other devices or a good routersim rather than buying a isdn sim. You may get some questions about ISDN, but it's not a very popular exam item any more. If you read my ISDN TechNotes a couple of times you should be able to answer any ISDN questions you may get.

Webmaster is right. If I only had a limited amount of time to study and had to leave one topic out so I could concentrate on others then I would forgo studying ISDN over any other. That's not to say you might not get questioned on it, and I would try to be prepared, but I would certainly not make it the central focus of my studies.

Nice one,

I've been thinking the same recently, and did see a failrly cheap one on ebay (£170) but thought "do i really need one?" so thanks guys for answering that one!

Fairly cheap, didnt really use it for CCNA, but getting its use for BCRAN if you intend to go on to CCNP

I have another question. Does anybody know of a website that deals with converting decimal to hex and vice versa? I haven't done this in awhile and really need to brush up. Thanks.
