Calibrate FXO Lines
The SBM can automatically calibrate its FXO interfaces, adjusting the audio
level based on the characteristics of the line. To calibrate the interfaces,
complete these steps:
1. Make sure that the FXO interface that you want to calibrate is connected
to the proper equipment provided by your PSTN carrier. Use standard
cables; refer to the installation guide for your telephony card for more
information.
2. Also make sure that the FXO interface has a valid configuration. If you
have arrived at this window from the PSTN Setup Wizard, you have
already created this configuration.
