System and method for adaption of data transmission rate depending on line quality and a modem suitable for use in such a system. |
| 摘要 |
<p>According to this system, the local (1) and remote (3) modems having, respectively, possible data rates of 4800 bits/s to 19200 bits/s and from 4800, 9600 to 14400 bits/s can communicate according to their common 4800, 9600 to 14400 bits/s data rates by adapting their data rate according to the quality of the transmission medium (85). Application: data transmission. <IMAGE></p> |
