DTE Interface Configuration Options

CT111_Rate Cntl: Disable

Nxt Disable Fallback1 Fallback2

CT111 Rate Control. Allows the DTE to control modem rate via Pin 23 of the EIA-232-D interface. This option determines the effect of the DTE Rate control signal. CT111 is also known as CH on the EIA-232-D interface.

Disable – Disregards CT111 Rate Control.

Fallback1 – Forces the modem to decrease its configured data rate to the next lower data rate when CT111 is Off. Valid only for V.32bis, or, if installed, V.29 and V.33 modulations. Modem will only fall back within the same modulation scheme. When CT111 turns ON, the modem returns to its previous data rate.

Fallback2 – Forces the modem to decrease two data rates while remaining in the same modulation scheme. When CT111 turns ON, the modem returns to its previous data rate.

NOTE: This configuration option is only valid in Async Direct mode and Synchronous mode. For proper operation, disable the V32bis Autorate and V32bis Automode configuration options.

The factory default is Disable.

AT command is S-register S61 = n, where n is 0 for Disable, 1 for Fallback1, and 2 for Fallback2.

DTE Rate=VF: Disable

End Disable Enable

DTE Rate = VF Rate. Forces the data rate of the connection between the DTE (computer) and the modem to be the same as the VF (telephone line) rate.

Disable – The DTE rate is the value of the Async DTE Rate configuration option.

Enable – The DTE rate is identical with the VF rate.

The factory default is Disable.

AT command is S-register S90 = n, where n is 0 for Disable, and 1 for Enable.
