I don't know how many new users you get every month, but those are
alarming rates. Fortunately we do not have anywhere near that.

This at least means that they can probably play with their own switch
all day to find the optimal settings. We do not have that luxuary here
in BellSouth land.

I am and have been a staunch PM3 supporter - however many of the reasons

We had this happened before - many times. Usually it's a padding change
but sometimes the telco'll add repeaters or cut over to new [physical]
lines without telling us.
BTW, I am not necessarily refering to physical line conditions - I
don't believe that's an issue either. switching padding, for example,
is definitely a sore point. My complaints about Livingston on this single
issue is long and is well documented by the list archives so I won't get
into it again. I know for a fact that Cisco and USR can do padding
compensation on the server side. You can even turn it on/off on the
Cisco (the AS5300 with MICA modems is really a cool piece of
hardware/software combination as far as features/tweaks/knobs, but I
don't know that it actually connects better). The PM3 is wonderfully
simple in that there's literally nothing to tweak, but that's a negative
when you are having problems.
