AS2 Parameters used in B2B Add On in SAP PI

Hi All,

I have a B2B scenario of Trading Partner (EDI using AS2 B2B Add On) ----> PI -----> (IDOC) SAP.  My trading partner provided their AS2 parameters (like AS2 identifier, AS2 URL, Port, Key certs, and encryption used) already to be used in AS2 sender commChannel.  They are now asking for my company's AS2 params to be used in their side. 

Question is for the AS2 identifier, url and key certs, how would I be able to determine these without going to Basis resource? 

I need help in determining these parameters. Thank you.
