V92_V44 MODEMS

9/30/2000

v.92/v.44 modems: A modem standard expected to be approved in September 2000. It includes a number of (minor) improvements over the 56K/V.90 standard. Specific Improvements:

10 sec connect time vs 20 sec for v.90
48Kbit/s uplink vs 33.6kbit/S for v.90
full 56kbit/sec downlink (already in v.90?)
Ability to put modem on hold (e.g. to handle incoming calls)
v.44 compression allowing substantial improvement over v.42bis

v.44 compression of 6:1 is claimed for "typical web material" giving effective download data rates above 300kbit/sec.

The benefits of V.92/V.44 require V.92/V.44 at both ends of the link. 48Kbps uplink also requires excellent line quality.
