IP DDOS and TDOS are really two different problems but yes we as ITSP's
and CLECs living in the IP space are absolutely susceptible to both.
Ive done a fair amount of research into both of these topics and we have
seen varying cases of both, but usually IP DDOS steals the spotlight
because the numbers are bigger and the effects are usually more
widespread whereas a TDOS attack is rarely felt by anyone that doesn't
live in the affected region or isn't actively trying to call the victim,
and usually telcos keep these issues pretty close to the chest.
I expect this sort of attack is going to increase in magnitude in the
coming 24-36 months as attackers figure out how to wield it. Mark
Collier gave a very interesting talk at one of the CFCA events on this
topic, though the focus was on the enterprise victim, but the lessons
are really the same. There just arent really any good tools to mitigate
this sort of attack today, especially at the carrier level.

It seems like almost every telephone company can be hit like that
except the ?largest?...
A denial of service attack by simply calling so many times it
fills up their main trunks.
And we saw how the large IP colo providers handle this for customers
who get dos'd. The amount of bandwidth they have is staggering and
they still cannot guarantee you will stay up if a ?skilled? attacker
wants you down. So you keep throwing money at it until you are
so well established online that you look at your monthly bill and
want to puke.
