The Run test button, located against each port, allows to test the subscriber line associated with
this port. When the button is pressed, the test will be executed (it may take up to one minute.) To see the
results when the test finishes, hover the mouse cursor over the 'result' link located against the respective
port, or open the test results window by clicking the link:
– Common result–test result status;
– Foreign DC voltage В (RING), V–foreign voltage in В wire (RING), V;
– Foreign DC voltage A (TIP), V–foreign voltage in A wire (TIP), V;
– Line supply voltage, V–line power supply voltage, V;
– Ringing voltage, V–call voltage, V;
– Resist A (TIP)–B (RING), kOm–resistance between А (TIP) and В (RING) wires, kΩ;
– Resist A (TIP)-GND, kOm–resistance between А (TIP) wire and ground GND, kΩ;
– Resist B (RING)-GND, kOm–resistance between B (RING) wire and ground GND, kΩ;
– Capacity A (TIP)–B (RING), mkF–capacity between А (TIP) and В (RING) wires, µF;
– Capacity A (TIP)-GND, mkF–capacity between А (TIP) wire and ground GND, µF;
– Capacity B (RING)-GND, mkF–capacity between B (RING) wire and ground GND, µF;
– Phone is connected-connected phone indication.
Test results description:
– OK–line test has been completed successfully;
– TEST FAILURE–invalid operand values were calculated during measurement. For example, division by zero
has occurred. This error may appear in line resistance and capacity measurements upon the expiry of
capacity measurement timeout;
– STATE FAILURE–occurs when the set detects leakage current, and during test, when the current line wire
mismatches the required state;
– RESISTANCE NOT MEASURED–means that during the line resistance measurement one of the values was
lower than the minimum allowed value (100Ω) As a rule, this error may be caused by a wire or ground short
circuit;
