Were I am aat the moment I haave lousy lines and only get 33600/31200

to David because He is on the front door step of his exchange.



I will probably be back up in FNQ in Jan/Feb/March were I will be

sittiing on the door of the exchange as well.

I will do some tests with you from there for sure.

And I will try from here to you this week some time...but it wouldn't

be to Flash.. I tell ya.



As I have said before if you want rock solid 33600/33600 both ends

have to be at the doorstep of their exchanges (you have to be able to

see it from your house.)

 Yes but, it can be a 57600/33600 PSTN link (if you are close to your

 exchange)



 JP> I can manage a 31200/31200 connect to M34Fs, but seemingly not 33600. I 



I am betting it is the difference in Trellis codeing or Constellation,

being the reason USR's cant get 33600 to Rockwells. 31200 would not be

pushing the limits of the Rockwell as hard and therefore is possible.

Thats Bill's theory... mine is above
