This is about what Bell is not providing, even though other
companies do. However, this is current technology, not obsolete,
which Karen <span class="gmail_default"

to need.<br>

natural that some here will see the issue as merely one of
choice and pace of technology, but IMO it must be seen as a
broader issue of problem-solving. If Karen's accessibility
needs require analog service in 2023, then that service is not
obsolete merely because it's convenient for Bell to declare it
so. In making a transition to digital it is Bell's
responsibility to either:<br>
<ul>
<li>provide a complete working solution to Karen's needs
that can be accomplished purely digitally</li>
<li>use whatever means required internally to maintain (what
is seen in her home as) analog service<br>

And if Bell is no longer able to provide the service she wants.
When I started in telecom, I was a bench tech and spent my days
overhauling Teletype machines. Suppose Karen needed a Teletype
machine? She will not find anyone able to provide that service, as
it's been obsolete for a long time. I chose that example, because
deaf people would often use Teletypes to communicate, using the old
300 baud modems. Teletype machines are long gone and dial up modems
aren't used much these days. So how would anyone get that service?
They wouldn't. Technology has moved on and there are now better
ways for blind people to communicate.<br>

Getting back to phones, in electrical engineering there's something
called transfer function. With this, you assume you have a black
box and measure the input vs output and compare things like level,
frequency response, distortion and more. If 2 black boxes produce
identical response, they will sound identical, regardless of what
they're made with (this is a concept that audiofools have a problem
with). In an earlier message, I discussed a bit about the
technology and CODECs, specifically the G.711 CODEC. If 2 devices
have that CODEC, they should sound identical. This leads me to what
I've been struggling with all along. That is what is she hearing
that causes the problem?<br>
