I had a question in my study guide about what the combination of TEI & SAPI
gives you.
My answer was 'A unique datalink layer address', but the answer in the book
said 'A unique network layer address'.
I had the understanding that this was info in the address field of the LAPD
protocol (Q.921) which is operating on the ISDN D-channel in the Datalink
layer.
Who's right, and if I'm wrong - could someone please explain why?
I hope this is a typo in the book, because just when you think you know what
the .... it's all about, you get thrown a "No, you're wrong" in the face...
Thanks in advance,
Ole
P.S. Besides the few typo's I've seen, so far this BCRAN book (from McGraw
Hill) is excellent!!!!
