Terminal Emulation Modem Enable - ADTRAN XR Quick Start Manual

Chapter 3. Installing an Analog Modem

Terminal Emulation Modem Enable

An alternative method is to use a terminal emulation package
such as HyperACCESS. In order to determine if an external
analog modem is properly connected to the Express XRT, issue
the AT command AT!Z (followed by Enter). If an external
analog modem is properly connected to the Express XRT, the
Express XRT responds with the message MODEM FOUND
(shown in Figure 3-4).
The AT!Z command is directed to the Express XRT not the
analog modem itself. An ERROR occurs if the command is sent
while the external analog modem is enabled.
If the external analog modem is not properly connected to the
Express XRT, the Express XRT responds with the message NO
MODEM FOUND.
