Update...well, January news....

In addition to driving widespread acceptance of the K56flex protocol,
Lucent has dedicated a leading research and
development team to setting industry benchmarks for analog modem
technology. Lucent's renowned Bell Labs developed the
company's 56-kbps technology to not only download information at top
speeds but also uniquely upload data to the Internet at
40 kbps.

Lucent's modem technology can also operate in a symmetrical mode, which
transmits data at 45 kbps in both the downstream
and upstream directions, a capability that significantly improves
applications requiring fast symmetrical rates such as Internet
telephony and videoconferencing.
