Correct voltages but no dial tone on TDM2400P
...When I "cat /dev/zap/24"
with the phone off the hook, I get random data, and talking into the
phone or hitting keys changes this data, indicating the TMD's adc is
working.
PHONE CONNECTION:
The Tip is connected to Pin2 on the 50pin Centronics, ring is connected
to Pin27. Ring is 46V below Tip on hook and 6.7V below off hook.
Is this the right connection for channel 24?
Why is there no dial tone coming through?
ASTERISK:
On the Asterisk side, I can set up sip phones and trunks, but no matter
how hard I try, I have no luck with the analogue phone. Currently
zapata.conf is set...

Logic problem in NUT with upscode2 driver
Hi All,
I have what is probably a 12 year old (or older) Compaq R3000 UPS
plugged into a FreeBSD 8 system running NUT version 2.6.5
This UPS contains a total of 16 batteries in 2 banks of 8,
each battery is 6 volts and the bank produces 50 volts.
The UPS monitors battery voltage and the battery charger in
the UPS works like this. For about 2 days it will apply a
charge/float/topping
