Hi Vallimamod, I use the Failover Switch from beroNet. See http://www.beronet.com/product/failover-switch/ Not for SS7, but for a few ISDN-2 lines, however the situation is the same. For SS7 we have 2 servers with 2 different pointcodes. The telecom company sends traffic 50/50 balances to both pointcodes. When one server is not available, the telecom company automatically sends everything to the still working server. But in that case, you would need 8 E1 links (4 for each server, so you don't loose capacity when one server is unavailable). And a cooperating telecom provider :) With kind regards, Robert Verspuy Op 29-08-13 13:37, Vallimamod ABDULLAH schreef: > Hello list, > > I have 4 ss7 E1 links with signalling plugged on one server. For redundancy, I am planning to add another identically configured server. I can make IP and asterisk failover with pacemaker but I also need a way to automatically "plug" my ss7 links to the new server. > > Is there some good simple switch for this task that anybody would recommend? Or any other way to solve this problem (I have thought of connecting each twin port pair in parallel with an Y splitted cable but I'm not sure it would work...)? > > Thanks! > -- *Exa-Omicron* Eenspan 8-K 3897 AL Zeewolde http://exa.nl @ExaOmicron <https://twitter.com/exaomicron> Meld support aanvragen nu via exa-support.com <http://exa-support.com> of via @ExaSupport <https://twitter.com/ExaSupport> -------------- next part -------------- An HTML attachment was scrubbed...
