Here is the example (Robert Hardy used USR Class 2.0):

The called faxmachine send a DIS frame, which could misinterpreted by some Class 2/2.0 faxmodems:

Send:     ATDT0W0019059478568<CR>
Receive:  <CR><LF>
Receive:  CONNECT<CR><LF>
Debug:    passing point (T) of T.30
Receive:  <ff><ETX>@            ATADERUP
Receive:  CSI                     
Receive:  OK<CR><LF>
Send:     AT+FRH=3<CR>
Receive:  <CR><LF>
Receive:  CONNECT<CR><LF>
Receive:  <ff><DC3><80><NUL>^<f8><80><80><88><SOH>
Receive:  final frame
Receive:  Subaddressing capability signaled
Receive:  DIS 19,5,0,2,0,0,0,0,0[,2]
Receive:  OK<CR><LF>

The first value of the above DIS is 0x19 (according to ITU-T.32) and means that receiver is 
capable:

0 ... 204x98 dpi
1 ... 204x196 dpi
8 ... 200x100 dpi
16 .. 200x200 dpi

It is a sign, that receiver has both inch and metric based resolution! A lot of class 2 (and 
maybe some class 2.0 too) modems do not quite understand such DIS parameters and will fail (in 
your case training).

Try another modem ...

Yes. *Sometimes* it manages to work :-)
