Yes,  I know, and it works with the Maroc Telecom, but the main 
problem is, that teh "HSS G.703" modul has only one port.

Yes, the "HSS 4-port WAN" module has FLEXWAN adapter cable for RS-232, 
RS-449, V.35, X.21 and EIA-530

So I can choose the FLEXWAN-X.21 Cable if I get them !

I was on the website, but they are realy expensive !

This will I check out now...

I do not know, because it is my first experience with WAN's of this 
dimension. The OC-3 in Paris/France is managed by <http://www.amen.fr/> 
and the two E3 in Kehl/Germany by UUnet, so I have no stress with it. 

But now it is quiet different...
Fortunately I have gotten most for free... (val. around 300.000 Euro)

Question:   If I have curently no E1, can I connect the 
	    two DSU-Modem to each other for testing ?
	    Or do I need the ISP's E1 between ?

My "NETBuilder II" is up and running and the "NETBuilder Office Connect 
221 Boundary Router" to. So I need to test it...

The 3Com Service does not respond to my questions  :-/
