Pawel at halo-kwadarat, has also done an analysis for SMG on 16E1, read his analysis and thorough testing methodology at http://wookieboo.halokwadrat.pl/lang-en/component/content/article/17-ss7boxsmg/29-ss7-smg-performance Although this is SMG specific, it does show workable solutions of 16E1 per server. I'm trying to get some time to do a similar analysis on libss7 and chanss7 and compare them to SMG, maybe sometime this weekend if it all falls into place. -wasim On Thu, Jul 17, 2008 at 1:18 PM, Krzysztof Drewicz < krzysztofdrewicz at gmail.com> wrote: > 2008/7/16 Patrick <asterisk-list at puzzled.xs4all.nl>: > > Antoine, > > > My 0.04 USD: > > >> There many unknowns to me: > >> For example I don't know if I can put 16 E1s per server? > > > > Not sure.
