To clarify, I'm talking about TDMoE between two asterisks. If you want
to use TDMoE to use ethernet based E1 interfaces, you'll need to see
how that hardware works.<br>
This channels per span stuff needs to be accepted from both sides.<br>

TDMoE generates 1000 interrupts/second just like any other DAHDI card.<br>
Interrupts is not the issue. 1000 irqs/sec is doable with much older
processors.<br>
What you need to worry about is echo canceling, transcoding, and other
issues.<br>
Also, a single TDMoE span can be used for at least 120 channels. TDMoE
generates 1000 Hz interrupts per span, not per channel. And TDMoE spans
using SS7 don't have the 24 or 31 channel limitation.<br>

<div>What about CPU interrupts? I have read TDMoE generate quite a
lot of interrupts that could cause the CPU no starve. </div>

<div>I saw the 8 PRI redfone gateway. Do you think I could run two
for a total of 16 E1 out of a XEON, or perhaps 2 XEON MB.<br>

<div>Last year, I have successfully tested chan_ss7 with 4 E1
phone
bridge. So its certainly doable . What I did was purely a test setup
throwing calls from one E1 port to other E1 port connected in loop back</div>

<div class="h5">Hi Gents,
<div><br>
</div>
<div>I was wondering if something has tried to interact Libss7
and TDMoE. </div>
<div><br>
</div>
<div>We are working on getting up a big linkset with our TELCO
(
up to 24 E1s) and would like to host the cards on multiple servers. We
are not sure even a modern XEON 12 core 3.33Ghz CPU can handle 720
concurrent calls.</div>
<div><br>
</div>
<div>I have found some documentation about TDMoE and some
mentions about doubt with CCS signaling... <a moz-do-not-send="true"
href="http://goo.gl/pBL6k" target="_blank">http://goo.gl/pBL6k</a>
This question as well has been asked before but didn't received an
answer.</div>
<div><br>
</div>
<div>Any information, documentation or hint is greatly
appreciated.</div>
