Algorithm Names
Similar to Five-Element Resistance with the addition of
Tip to Ring and Ring to Tip resistance differentiation in
order to detect a non-linear element such as a diode.
To detect the presence of an M-Socket used in Hong
Kong and a passive test termination (PPA - Passiver
Prüfabschluss) used in the German telephony network.
An M-Socket termination diagram is presented in
Figure
Figure
To measure the POTS splitter filter located at the CO end
of the loop. Two zener options are provided,
VPTL_ZENER_24V and VPTL_ZENER_36V. CO splitter
signature types are presented in
To detect CPE splitter and Integrated Access Device
signature types. Zener and mode input parameters allow
for discrimination of the various networks. Signature
network diagrams are presented in
Figure
To detect if an ISDN terminal is connected at the
customer end of the loop. Targeted at detecting a
German NTBA (Network Termination Basisanschluss).
To measure the capacitances connected between Tip
and Ground, Ring and Ground, and Tip to Ring. This test
also measures foreign AC voltage. The test can measure
foreign voltage sources in excess of the SLIC power
supply rails.
To measure the capacitance connected between Tip and
ground, Ring and ground, and Tip and Ring with control
over the test stimulus voltages and frequency. This can
be used to implement a low capacitance phone detection
algorithm.
To verify the difference between a receiver taken off hook
or a line short.
To diagnose a line to locate a cable cut. Return the
distance in meters between the central office and the
cable cut.
To measure the AC current flowing in each lead when the
line is set to a specific common mode voltage.
