While listening to david begley Pete heard:M34F Status Codes

G'day david

 db> After stuffing around with tests (to see whether or not it
 db> works, so I have a "solution" for future reference), I've gone
 db> back to %L11 (ie., -11dBm).

Louder is not always better, FWIT v34 just uses the dB setting as a
starting point as it probes the line to decide on the best Tx level.

 PC> I think -10dBm is the limit on loudness can't comment on the
 PC> other direction.

 db> The reason why I picked -9dBm for testing was because I'd seen
 db> it mentioned in a PC telecommunications book that on average, it
 db> was "the best" possible transmit level (in the U.S., anyway).
 db> I've also tried -10dBm and it didn't help, so it's one of those
 db> "just over the edge" modifications.

I think the Aust max level is 1 dB softer than the US standard.

 PC> Not sure here, USR's seem to come into their own on bad lines,
 PC> they'll work where others give up and drop the line.

 db> Bill seems to think this has something to do with the 64-state
 db> trellis coding;  can someone explain to me *why* this is so?  I
 db> have diagrams of the trellis coding procedure used in V.34, but
 db> no rationale.

I've no idea what Trellis Coding is apart from the fact that 64 state
sounds better than 16 state.

 db> > (still have a Series 3 M7F in a box here!):

 PC> Power user :-)

 db> You bet!  Although I'm not *that* "feature-centric" that I'll be
 db> getting one of those new 288D modems (I ignored the "Digital
 db> Secretary", too).  I'll wait for V.34bis.

I'm not really into bells and whistles either, reliability and speed
are more important to me, if i want an answering machine i'll buy one
i don't want my modem to do it.

 PC> USRobotics seem to have put a lot of R&D into their DSP based
 PC> modems so maybe Netcomm didn't have the resources to develop
 PC> something like that, i'm assuming the corporate size of USR is
 PC> far bigger than Netcomm, Wonder if USRobotics has a marble foyer

 db> NetComm has been entering into alliances left, right and centre;
 db> they've just joined forces (Feb 23, 1996) with Boca Research in
 db> the U.S. (another modem maker), so who knows...

Could be an attempt to break into the US market, i'd assume that's
where the big money is.

 PC> I think a lot of Pauls problems are caused by the Qty of his
 PC> phone lines.

 db> Apparently the Maestro SE just died, so maybe *it* was on the
 db> way out. :-)

That might have been it. BTW i tried Pauls BBS with my M11F and got a
good 28800 vfc connect, only requested his filelist so i wasn't on
for long but the connect seemed fine.
