I saw a mention of pppd problems on the kernel mailing list but that was 
fixed in 2.4.1 apparently.

My version of the problem seems to have been fixed by changing the ISDN TA, I 
tried a firmware upgrade with the USR Imodem which improved things slightly 
but switching to a Tron 128 seems to have fixed it completely!

I gather that this type of TA does the ppp (& multilink ppp) itself and 
spoofs a ppp session back over the serial port which contains the data from 
the session over the line, phew, complicated or what! So if there is a ppp 
problem between you and the ISP it's the TA's fault and nothing you do on the 
linux side will fix it. If the problem is between linux and the TA then 
that's a different story.

This doesn't directly help your situation other than to indicate that the 
problem (if it's the same one) may be in pppd.

The question over mtu's arises in that apparently windows always sets the mtu 
to 576 (old fashioned ethernet mtu) on links slower than 128k so I expect 
most ISP's rarely test their configs with much else.

Got to be worth a try
