Advanced Configuration of the XT Series
The XT Series can receive AT commands from its network connection to the controller's IP
address over port 55003, or from its USB connection to the controller's serial port connected via a
standard RS232 cable.
You can use AT commands to control all functionality of the XT Series available in the endpoint or
web interface.
Before using this functionality, you must enable AT command management in the XT Series. You
can restrict whether AT commands are allowed only over the RS232 cable or over the network
connection, and you can also restrict the range of IP addresses allowed to control the unit. For
more information on the supported AT commands, contact your local customer service
representative.
You can remotely monitor XT Series using Secure Shell (SSH) from the Command Line Interface
(CLI). This feature enables you to remotely control XT Series using the AT Commands API. You
must open port 22 in order to connect. You can update the firmware, retrieve the log files, import
and export the configuration file, and reboot XT Series using the SSH CLI commands. If you
attempt to connect to XT Series and you enter an incorrect password, the XT Series prevents
access for a limited duration.
For more information, see the Avaya Scopia
Before you begin
Ensure you have the IP addresses and the subnet mask of the devices which remotely control the
XT Series.
If configuring from the endpoint, you must first enable advanced configuration, as described in
Enabling Advanced Maintenance on the XT Series
Procedure
1. Access the AT settings. From the XT Series web interface, select Administrator
Settings > Utilities > Remote Access > AT Commands. From the endpoint's main menu,
select Configure > Advanced > Utilities > Remote Access > AT Commands.
