Hi!  
If for example, I’m going to install an asterisk to a client that need 1Port T1 card, what parameters i need to ask to the client ISP ?  
I mean, … I need somes ISP parameters to get the T1 card configured or the parameters are standard?

You’ll want to know the framing and the coding.  
You’ll want to know the signaling type - is it a PRI, is it E&M?  
You’ll want to know how many voice channels you’ve got. If it’s PRI where your d-channel is.  
If it’s PRI, what type of PRI signaling is it.  
If it’s E&M, you’ll want to know whether it’s immediate, wink, or Feature Group D.  
You’ll want to know how many digits you get on dialed numbers.

That should get you going.

Can you please, provide a sample configuration for a E & M?

That’ well help to much!

No, I can’t.

The manuals for Digium’s cards may be of some help. Digium’s Support department can also help you if you’ve got trouble with your Digium product.
