 I have just used the Telstra Faxstream Testfax Plus number three
 times using the 5/7/95 SDL, 18/7/95 SDL and the one referred to
 above. I have received reports back on each of the
 transmissions.

 The 5/7 code results received a "POOR" rating because the
 transmission level was -8.6dBm and was reported to be 10.4dB too
 high (loud).

 The 18/7 code received a "FAIR" rating with a -13.0 dBm
 transmission level and was reported as being 6.0dB too high
 (loud).

 The recent hacked US code also received a "POOR" rating with the
 highest transmission level of -8.4dBm and was report as being
 10.6dB too high.

 The recommended Telstra transmission level for Faxes is -19dBm
 as the optimum and lowest level. For analog telephone exchanges
 a level of between -19 to -16dBm is said to be satisfactory.
 Lower levels are said to help overcome some echo problems.

 All faxes sent by my OZ Courier (all three SDL's) were
 transmitted 100% error free at 14400 bits per sec at fine image
 resolution.  Line noise level of -54.9dBm were reported as
 excellent.

 I haven't sent many real world faxes with the Courier so am
 unsure as to what the readings mean in practice. I can say
 though, that I haven't had any failures in the fax transmissions
 so far.

 Anyone want to comment.


 Rob
