That is, if you have a K56Flex by Conexant – formerly Rockwell. This speed is set during the installation process when you install your modem and modem driver software.

Here are some selected measurements from their tests: These claims are NOT real world. Faster Connection Negotiation Time. Noise on the phone line you may not be able to hear. Under the best conditions, 56K modems top speed in the US is This is particularly useful for lines that have call waiting.

The distance may effect the receive levels of both modems putting the needed signals close to the noise floor. Compression operates by removing redundancy in a file.

Here are the standard DTE speeds. It is the speed between the two modems.

Views Read Edit View history. US Robotics X2 is practiaclly obsolete now. If you cycle power or inject a ‘hard reset’ after every connection there is no advantage.

They were both turned down. During the MOH function, data transmission and reception is stopped.

You can see that the pkzip is much more effective than any modem compression, and the difference in the results between the pkzip and V. ITU-T surmised that once your modem makes the calculations for the first connection, these calculations should not change unless you change locations.

V90 V 56k Modem Speeds

Quick connect — appx seconds — vs V. Both Rockwell and US Robotics the first producers of 56k modems requested the FCC allow their modems to transmit at a higher louder level allowing the 56Kbps speed. This page was last edited on 22 Augustat Asymmetric means the upstream speed the data you send is different than the downstream speed the data you receive.
