How can he trust you dude when you don't know anything about a TNT?

Here is one for under $8000 that is configured to handle a full DS3 with 
hardware echo suppression and it can also take v.92 modem calls.  They have 
had a full DS3 card since at least 1998.

Your equivalent in Cisco is just under $42000.

I am not bashing Cisco.  I am a fan and have configured many Cisco 
routers.  But I have a pair of TNTs as an * gateway (one for a hot spare) 
and they cost a heck of a lot less than a pair of 5400s.  Our dialup TNT 
has been rock solid for many years other than a power supply failure.  Now 
if the TNT only ran IOS instead of TAOS....
