ISDN on the ICND exam?

I seem to remember reading that ISDN doesn't feature on the ICND exam anymore, can anyone tell me if this is correct or am I subconciously wishing it away? I've checked the Cisco website and its right at the very end of the blue-print for the exam.

I wish it wasn't.......

I took the 640-801 recently, and my recommendation to you is: don't spend much time studying ISDN.

That would be my recommendation but not because I have taken the test, but rather because it's a minor topic on a 50-60 question test. Unless you're just plain unlucky I can't imagine more than 1-3 questions on it and even three seems to be pushing it since 3 questions is >= 5% of the test questions. So I would know things like the standards used to define ISDN, basic properties of BRIs and PRIs, and the necessary configuration commands to make an ISDN connection.

I just passed the 640-801 as well and fully agree with this.

Let's just say that I didn't put very much if any time into studying ISDN or DDR and my score did not suffer any...

According to the 640-811 ICND exam blueprint...

Since ISDN is listed on the ICND exam blueprint, it is fair game regardless of those who have reported that they didn't get any questions about it. Please do yourself a favor and do not get a false sense of security because others didn't get questions about it. In other words, make sure you are properly prepared for the exam by studying everything in the ICND blueprint, including ISDN.

Here's an overview of ISDN from Cisco.

ISDN is a fading technology, you may be asked a few technology topic questions over ISDN (like adapters, channels etc w/e) but none of the sims will be over ISDN

ISDN is no longer on the CCIE Lab either.
