Bait, hook, line, sinker - alright here goes.

IMHO Telecom have pumped Jetstream full of morphine. There are broken bones
everywhere but nobody can feel the pain.

Example. If you unplug the DSL line from a SpeedTouch Pro and then plug it
back in 15 seconds later, everything may continue as if nothing happened.
There is no logging that DSL failed, PPP stays up and TCP connections will
often "recover" (it ends up being a 30....45 second outage).

This new feature turned up about the time Telecom claimed they have fixed
the problem with DSL line failures, prior to that PPP would have
disconnected, the ISP would see a Radius event and the users TCP sessions
would probably die (loss of NAT state).

So rather than fix the cause they have fixed the effect, DSL outages now go
unnoticed unless you are like me and actually care that an interactive
session keeps "freezing".

This fix is probably OK for the average home that uses the DSL for Web
surfing only, they may consider slow loading sites "normal" and a DSL outage
will appear the same.

But for a business it has created a support issue, gone is any evidence of
what may be causing problems, this affects both Jetstream, IP.Networking and
IP.Remote. We have users with DSL lights "flashing like mad" every five
minutes, ring the DSL Help Desk, no line errors, no disconnects "a perfect
line".

Dunno, I'll reserve my decision as to whether this is a "fix".

Cheers

BG.
