There is a cretain application (which is important to hearing impaired),
for which all the intricate and convoluted calculations of d/l:u/l ratios
are completely irrelevant:
VIDEOPHONES
This application is characterized by d/l:u/l ratio of 1:1. For people who
need this application, the restricion to u/l rate of 64Kbps spells a
disaster, as sufficiently high quality video needs rate of 384Kbps.
