Out-of-Service Physical Reasons for FXS Port

The device takes an FXS physical port out of service when any one of the following occurs:

■

The Serial Peripheral Interface (SPI) connection with the port is lost. The device sends the SNMP alarm acAnalogPortSPIOutOfService for this out-of-service reason.

■

The temperature of the port has exceeded the temperature threshold for normal operation. The device sends the SNMP alarm acAnalogPortHighTemperature for this out-of-service reason.

■

The port is inactive due to a ground fault. The device sends the SNMP alarm acAnalogPortGroundFaultOutOfService for this out-of-service reason.

When the FXS is taken out of service due to any one of the above, the device sends the SNMP alarm acPortServiceAlarm.
