Perhaps this message should be splitted among smaller ones, but anyway
here it goes... Just moved to a new house. A 16-meter phone cord was
installed to connect my Zoom, Lucent-based winmodem (Lucent generic
drivers ver. 6.00 installed) to the wall
jack. A check was performed that the connection is OK. A 50666 bps
connection was established on the first try. Just to make sure, I
tried to connect a couple of more times. Same figures.
Then a high WAF* figure is raised and the phone cable has to follow an
invisible route, hiding behind furniture and the rest. Since the cable
can not reach my system now, 5 more meters are bought and hand-wired
to the the former's end. The other end of the new cable is plugged to
the line input of my modem. Furthermore, a couple of other changes
1) A small plastic channel was installed to carry the phone cable and a
shielded TV antenna (RF modulated) cable. The RF cable runs in
parallel with the modem one for approximately 5 meters.
2) A second phone (DECT technology) was connected to the wall jack.
To make a long story short, I tried to connect again. To my
dissappointment, connection figures of 48000 bps were reported this
time, while V.34 connections were also made from time to time. The
48000 bps rate does not change during the call, but the
transmit rate is changed 28800 to 31200, per information provided by
ATI11. Additionally, ATI11 "Estimated Noise Level" is usually in the
280 region (wish someone could provide some info on this figure for the
specific rate: good? bad?). No RBS/digital pads present.
Backtracking into what has changed I unplug the antenna
cable from both ends, as well as the DECT telephone from the wall jack
(however, it is left "active", i.e. the DECT base is operating). What
else could have affected the connect rate? Would any post-call
diagnostics help identify the cuplrit?
