</div>No you couldn't. The 56k link uses FISUs when there's nothing to say, so<br>
when you throw in IP and PPP overhead you won't even be able to align<br>
your link.<br></blockquote><div><br>Yes i could: I don't use FISUs, i don't put any signaling in TDM, i just put there a PPP on let's say TS16 and in that PPP there is IP, so there is SIGTRAN, so my link has 64k and it's aligned, right? (not that this is a clear way, and anyone should use this, just a thought) .<br>

But no, I don't want my data network to engage in fate sharing with my<br>
voice network. There's no such thing as critical DNS traffic when you<br>
compare it to how critical a IAM is, especially if it's for something<br>
like an E911 call.<br></blockquote><div><br>Ok, USA E911, i say European 112. If you have your private exchanges and you are linked with 2 Mbps classic links, well it's cost saving. Just a thought what _could_ be done, ok? <br>

On Asterisk , SS7 is free. </blockquote><div><br><br>On Asteriski, there is a free SS7 for voice, and there are some commercial ones.<br><br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
On my "real" switch, it was such a small part<br>

So why try to add complexity to a network critical part of your network?<br></blockquote><div><br>Just cost-saving.

My SS7 is built into my DC powered switch. </blockquote><div><br><br>And how often you train your batteries? -48Vdc is fine for me, it's normal for me.

Adding IP in that would let me put it over my<br>
AC powered data network, </blockquote><div><br>AC<>DC, there are power inverters, and to my knowledge, some vendors use 230Vac (110 in your parts) powered servers for example for billing with doubled inverters. Also: my beautiful switch gives me 802.3af (to ip phones) and it has double AC power and batteries. <br>

convergence issue, or there's not a DDoS on my data network, <br></blockquote><div><br>No, no no, i say: point to point IP link. <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br>
So what's the argument for SS7 over IP again?<br>
<br></blockquote></div><br>No budget for DS3.<br>Easy to debug and to dump.<br>SS7 over ip is being *used* by many high shelf level vendors internally in ss7 switches, no point in translating into a SS7 over TDM, and on the other end of the wire, TDM to IP. <br>
<br>And by the way: i don't force anyone to use it, I just see some advantages.<br><br>Ok, it's asterisk list, so EOT as for me, if you whould like to exchange some more arguments please go off-list, ok?<br><br><br>
