David & Micheal:
Micheal first. Yes, I stand corrected on that. I wrote my reply at 3am, and
was fighting an allergy attack. So I was not totally awake. Nitin, if you
recall, has been on this group only recently to my knowledge, and I was trying
to layman it.
David next. But you sir are most correct on that. Ohms law, being that it
is. The impedance is remaining constant from the telset, and increasing the
emf should double the loop current, and therefore drive the circuit more
efficiently.
The point I was trying to make was in the telephone's electronic sensitivity.
One most also consider that this is a TD1232, and the A/D conversion of the
codecs come into play here also. Panasonic taught us in class that the max
"guaranteed" throughput for an XDP port was 19.2k due to the codecs.
Typically
I've seen 24.6k. But again this is bandwidth issues and a normal talk path
should be adequate. Possibly the valuation of the D/A conversion provided by
the codec is the issue here, or it's just a crumby older telephone they are
using. Again, the point is there is a loss, somewhere.
Sentimental attachments to tangible property maybe another factor. The end
user may have this favorite old phone, for example. We have been told it is
a SLT, but no make or model, or condition of said telephone.
