Hi, since you have been studying this stuff for a while, why don't you try answering that yourself as an exercise?

If is not difficult once you understand the basics on each type.

If it is not a quiz, what problem are you trying to solve? Seems to me you're studying for certification.

I think you should focus on your training material, and reason on it.

It is not that you can resort to this forum for any doubt, you've had many already.

I think cisco make this forum for all.

I will answer and you can tell me the true or false, deal?

AT analog the FXO: send only DNIS to PSTN and canot receive it

e&m: send and receive DNIS/ANI

FXS: i canot find any data about this

AT digital: E1 R2 CAS can send and receive both also the pri

T1 CAS E&M give more choice but if we use any signaling expect E&M i canot get any data about it.

So plz tell me.

Yes the forum is for everyone, but the other students pass the test without asking here, so why you should be different ?

However, FXS it's the other side of FXO, so think about it. Also think caller ID.

E&M: there is no defined universal standard for sending ANI.

PRI and BRI have DNIS/ANI natively.

1st issue : it is a wrong thinking if we confine VOIP technology as a test and result, we are engineers so we must understand this technology before we thinking in test, so i try to get the right informations.

2nd issue : Thanks for help.
