subject: Modem tests continue

Further to my last - bad conditions continue.  The Microcom still holds.

After D/L of some 3.5 Mb at just under 3000cps, I took some stats.

70+ Blers, 5 retrains, two from one end, three from the other.  The line is
rotten, with some sort of recurrent interference. 

Looks like the error handling on the DeskPorte is pretty hot stuff - and
this may be what's making it through.   Doesn't explain the E5 doing so
well at 9600 though - perhaps it's just narrowband enough not to see it??

Interesting - the Tx/Rx levels are about 8db down on the usual.  With the
VFC, this should not be dynamically negotiated, as I remember.

Gain changes?   Level shifts?   Crikey.  Give me a BREAK Telstra...

Don't want Franks' job thanks.. not a bit of it.  Hope Optus local loop is
better. Sure gonna try it.

Regards,
Dave Hatch.
