Adaptive Rate System
With the Adaptive Rate System enabled, the 326X Series Modem continuously
optimizes its transmit speed within the V.34, V.32bis, V.32 (coded and uncoded),
and V.22bis modulation modes. By constantly monitoring signal quality, the modem
adapts to the optimum transmission rate allowed by line conditions, ensuring
maximum throughput and efficiency.
Troubleshooting (V.54 and V.22bis Tests)
The modem supports a full range of ITU-TS V.54 and V.22bis compatible tests to
help isolate and correct problems.
Refer to Chapter 6 for typical problems and ways to correct them. Chapter 6 also
lists the supported diagnostic tests, and instructions for initiating and terminating
tests using either the front panel control keys or AT commands.
For details on tests, refer to Chapter 4 of the 326X Series Modem Reference Guide.
