Algorithm Names
To measure REN characteristics of regular or electronic
phones.
To measure REN characteristics of a phone attached to
the line taking into account loop conditions.
To detect and measure a DTMF digit, pulse digit, or hook-
switch flash.
To measure the sum of the line circuit noise and the
subscriber loop noise using one of the many weighting
filters − Flat, 3-kHz, 15-kHz, 3.4-kHz, CMSG, D-Filter,
Psophometric.
To measure the signal to noise ratio due to circuit noise
and quantization distortion while applying a 1010 Hz test
tone to the loop.
To measure the frequency and level of an arbitrary single
tone that may be present on the loop.
To generate specific tones to a specific line. (Generate
up to 4 tones)
To generate a tracing tone on a single wire.
To measure the Trans Hybrid Loss of the line circuit
under test.
Apply an off-hook load and detect the presence of dial
tone on the loop. Return the characteristics of the tones
(amplitudes and frequencies).
When used as a test head, to verify the ac/dc current
generated by another line.
To verify the capability of the SLIC to drive currents into
a load and to measure the voltage developed across it.
To verify the capability of the line card circuitry to detect
on-hook and off-hook events.
To verify the capability of the line card circuitry to
generate a ringing voltage at the desired amplitude and
to perform ring trip upon an off-hook event.
To measure the ringing voltage while applying normal
ringing on a terminating call.
