FXO Line Testing

The device can test the telephone lines connected to its FXO ports, using the SNMP
acAnalogFxoLineTestTable table. These tests provide various line measurements. In
addition to these tests, a keep-alive test is also done every 100 msec on each of the
analog ports to detect communication problems with the analog equipment:

Line Current (mA)

Line Voltage (V)

Hook (0 = on-hook; 1 = off-hook)

Ring (0 - Off; 1 - On)

Line Connected (0 = Disconnected; 1 = Connected)

Polarity state (0 = Normal; 1 = Reversed, 2 = N\A)

Line polarity (0 = Positive; 1 = Negative)

Message Waiting Indication (0 = Off; 1 = On)
Note:
