User's Manual 62. Analog Line Testing
62 Analog Line Testing
The device can test the telephone lines connected to its FXS and FXO ports, using the
SNMP acAnalogFxsLineTestTable table and acAnalogFxoLineTestTable table
respectively. These tests provide various line measurements. In addition to these tests
(detailed below), a keep-alive test is also done every 100 msec on each of the analog ports
to detect communication problems with the analog equipment and overheating of the FXS
ports.
FXS line tests:
• Hardware revision number
• Temperature (above or below limit, only if a thermometer is installed)
• Hook state
• Coefficients checksum
• Message waiting indication status
• Ring state
• Reversal polarity state
FXO line tests:
• 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: Use the Analog Line testing mechanism only for monitoring and never when
there are calls in progress.
