Sorry for double post - google shortcut and botched up keystrokes made me send premature<br><br><div>All - wanted to say thanks for enlightening me. Been a very interesting thread. Seems like there's a lot of legacy technology, regulations, and thinking that we have to take into account in planning. The original thread was on geographical redundancy - guess it should have been more specific:<div>
<br></div><div>* redundancy for an ITSP only provider that's facilities based reseller (that being someone who is not a true CLEC but uses CLEC(s) for IP <-> TDM conversion to get on the PSTN)</div><div> - SIP peering redundancy via IP</div>
<div> - local call processing and media gateway redundancy as well as geographical</div><div> - IP reachability to CPE and CPE redundancy</div><div><br></div><div>* redundancy for CLEC/Carrier</div><div> - some or all of the above and </div>
<div> - sounds a bit more complicated when you add on SS7 requirements</div><div> - what else?</div><div><br></div><div>Alex - to answer you directly - ITSP with either I guess would be relevant. Although if I use a wholesale provider I'd expect that they are both locally and geographically redundant (or I wouldn't use them unless business requirements or financial situation dictated outage time is OK or worth the risk). </div>

If I remember correctly tho, in order to connect to the tandems you had to be able to provide ss7 services. We got all of our ports out of a DMS500, but I do remember people using something<br>
from cisco to emulate a switch (SCC maybe?) and back end all the dial traffic into 5800's....<br>

<br>
There were lots of switch-lite solutions (signaling gateways) that were popular during the dialup boom. The Cisco PGW was very popular among them. All of these could control media gateways via H.248/MEGACO or MGCP, and the TNTs did H.248. Just very basic SS7 ISUP->media gateway control was needed to get modem pools going.<br>

<br></div>
And the Cisco AS-series stuff is MGCP, I believe.<div><div></div><div><br>
