The use of balanced drivers allows EIA/TIA-449 signals to travel greater distances than the
EIA/TIA-232 standard. Table 2-2 lists the standard relationship between baud rate and
maximum distance for EIA/TIA-449 signals. These limits are also valid for V.35 and X.21.

Caution
Exceeding this maximum could result in loss of data and is not recommended.
