That I realize that baud and bit/sec are not the same, but I feel you would
have a hard time getting a 56k modem to work on a line that does not
support 28.8k fully, let alone 33.6k. A leased line (copper pair)
from telstra only supports 9.6k and costs close to ISDN.
When the telco reinstalls the literal tons of copper cable that
we have lying underground for at least 20 years in some instances
that connects the exchanges, and replaces this with optic fibre
preferably, or at least higher bandwidth co-ax, we will not have 28k
even.
In the states you have better lines and ISDN is far less
expensive. For two B channels perminantly connected I have to pay
about $2500/month in this country. Not many home users can pay this,
thus they have to still use modems. With the lack of bandwidth to and
from the exchanges, there is not a chance in hell a 56k modem will
work in this country for many years.
(Australia - the lucky country...not in regards to bandwidth)

I'm trying to guess on the magic at work.
Note that the far end must be a PRI. I wonder if they do some
guessing as to the quantization points, then iterate.
Also note there's no mention of the hype-writer's old friend,
compression.
