Other Tests
The 923LTS may come equipped with other tests that do not require an ALTS responder.
They provide detailed results that can be viewed only on the 923LTS (i.e., results are not
collected in the ALTS database). Built-in tests may include:
100 Responder Noise Measurement
The 100 responder noise measurement operates with a type 100 quiet termination test
line.
102 Responder Loss Measurement
The 102 responder loss test operates with the type 100 milliwatt test line.
Perceptual Speech Quality Measurement (PSQM)
The built-in PSQM test operates with a Sage PSQM responder.
