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: * redundancy for an ITSP only provider that's facilities based reseller * redundancy for CLEC * On Wed, Aug 12, 2009 at 7:15 AM, Alex Balashov <abalashov at evaristesys.com>wrote:

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 from cisco to emulate a switch (SCC maybe?) and back end all the dial traffic into 5800's....
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.
And the Cisco AS-series stuff is MGCP, I believe.
