[Asterisk-Users] ISDN EDSS1 protocol support

[Maxim Litnitsky]

Hi all, I have to implement the following:

--------------
              |   ---- 10 voice channels   --------------------> 
|-------------------------------|
Prov  E1 |   ----  256 kbit/s for VoIP -------------------->  |
Asterisk IP-PBX      |
              |   ----  256 kbit/s for Data (http,mail) -----> 
|-------------------------------|
--------------

Provider gives E1 and on this E1 I will have 10 timeslots for voice,
and others for internet.
What hardware shall I use? Provider supports EDSS1 ISDN protocol, as 
I undertood Digium hardware does not support this protcol. I searched
google and lists.digium.com and found only
this:

The question: Can I implement all with Asterisk using EDSS1 protcol
and how?  Give me please a clue!!
