I'm told that people on Max Premium, with the double-speed uplink, are limited to a BRAS IP profile of 6500, even if their downlink syncs at the full 8128Kbps. In other words, if you start off with a 7150 profile and then upgrade to Premium, your profile will drop to 6500, even with enough sync speed to maintain the old profile. Can that be right?

All that said, your line is not usual - are you on your own cable pair back to the exchange? With that attenuation and Noise Margin to be syncing at 8128 is quite something. Maybe your cable is 0.9mm instead of the standard 0.5mm, whatever, that's some line (unless you've been editing the figures to wind us all up a bit

The initial quarter mile is overhead, so that may be higher-spec cable. It then goes underground to a PCP that's very close to the exchange itself. I'd say the line distance is about a mile or two, depending on the actual route.
The exchange connection had a lift&shift last week. The previous stats weren't quite as good as this, but the equipment was ridiculously congested at peak times.
Errors seem low to me (those stats were after about four hours uptime), so I'll probably request interleaving to be disabled if it hasn't happened after 10 days.

FEC Errors (Up/Down): 329 / 0
CRC Errors (Up/Down): 323 / 24.843
The point is that in my case the upstream is interleaved and the downstream isn't - they were both interleaved until the engineer initiated a reset of the downstream after the fault was hopefully fixed (E side pair change)

Quote from: richij Anyone know whether this is true? Or is it another one of those "Max Myths"?

Max Myth!
I've had 8128 down, 832 up on two different exchanges (both since upgraded to 21CN).
I'm currently on 7584 down, 832 up on a third exchange (no sign of 21CN) with a downstream attenuation of 21db. There's a problem on the line and the engineer due tomorrow so we'll hopefully see what I can get soon.
