8.3.4 CPE Modem Detection and DSLAM Detection
The CableSHARK’s DMT test will automatically determine if there is a CPE modem or DSLAM connected to
the far end of the circuit and will use the training frequency patterns as described by ANSI T1.413 to predict
the expected data rate of the circuit. The test will work provided that the equipment conforms to ADSL
specifications ANSI T1.413, G.DMT, or G.Lite. The DMT test will provide the user with an indication on the
status bar what device was detected – either an Annex A or Annex B modem or DSLAM.
