40 Line Testing
40.1 FXS Line Testing
The device can test the telephone lines connected to its FXS ports, using the SNMP
acAnalogFxsLineTestTable 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 and
overheating of the FXS ports.

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
For MP-124, you can also use the following Command Shell commands to view line status
and electrical measurements per FXS port or phone number:
LineTesting Port <port number> <test type>
- or -
LineTesting Phone <phone number> <test type>
Where <test type> can be one of the following values:

0 = Line status, which includes the following:
•
Hook status – on-hook (0) or off-hook (1)
•
Message Waiting Indication (MWI) – off (0) or on (1)
•
Ring – off (0) or on (1)
•
Reversal polarity – off (0) or on (1)

Line electrical measurements:
•
1 = DC Voltage Tip-Ring [V]
•
2 = DC Voltage Tip-Ground [V]
•
3 = DC Voltage Ring-Ground [V]
•
4 = AC Voltage Transmit(Tel2IP) [dbm]
•
5 = AC Voltage Receive (IP2Tel) [dbm]
•
6 = AC Voltage Transmit & Receive [dbm]
•
7 = Current [mA]
•
8 = Resistance Tip-Ring [Ohm]
•
9 = Resistance Tip-Ground [Ohm]
•
10 = Resistance Ring-Ground [Ohm]
•
11 = Capacity Tip-Ring [F]
•
12 = Capacity Tip-Ground [F]
•
13 = Capacity Ring-Ground [F]
•
14 = AC Voltage Tip-Ring [V]
