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 DCP when No
Data Disconnect is disabled. The factory default is TXD or RXD. The reloading of factory defaults does not affect No
Data Disconnect Trigger Signal.
TXD and RXD – Disconnect if no data transmitted and received for specified period.
TXD Only – Disconnect if no data transmitted for specified period.
RXD Only – Disconnect if no data received for specified period.

Automatic Make Busy. Forces the modem to go off-hook under the following conditions: a local analog loopback is
performed, a self-test is performed, or if the modem is switched to the service line. This configuration option is valid only
with the 3811

Exchange (PBX). For 3811 Plus modems, the MakeBusy Network Interface Modules (NIMs) must be installed on
