NoDataDiscTrig: TXD and RXD

Nxt TXD and RXD TXD Only RXD Only TXD or RXD

No Data Disconnect Trigger Signal. Works in conjunction with No Data Disconnect (\T), and determines whether Pin 2 (transmit data) or Pin 3 (receive data) of the modem's RS-232 serial interface is monitored so that the modem can disconnect the call if there is no activity for a certain period of time.

The No Data Disconnect Trigger Signal configuration option is unavailable and is not displayed on the SDCP when No Data Disconnect is disabled. The reloading of factory defaults does not affect No Data Disconnect Trigger Signal.

TXD and RXD ± Disconnect if no data is transmitted and received for specified period.

TXD Only ± Disconnect if no data is transmitted for specified period.

RXD Only ± Disconnect if no data is received for specified period.

TXD or RXD ± Disconnect if no data is transmitted or received for specified period.

The factory default is TXD and RXD.

AT command equivalent is S-register S80=n.
