Alcatel's S12 (well, it was made long time ago and not by Alcatel) also
should talk DSS1 aka EuroISDN natively, but (as very many new designs) it
may need extra license to speak EuroISDN, so sometimes Asterisk is not
expensive way to add SS7/EuroISDN/SIP/IAX/H323 capability to existing pbx.

if running so many E1, I whould recomend on seeing Sangoma's option for
ss7box or Dicea's solution to be able to have at least two servers, and
cluster capability. And i whould go not for one box, but many box, it would
allow for some redundancy (>=2 signaling links) and possibility to extend
hardware to support more E1s.
