Chapter 41 Loop Diagnostic After the DELT test completes, a summary report displays at the bottom of this screen. This is an example. Figure 222 Dual-End Loop Test Report The following table describes the test report labels in this screen. Table 163 Dual-End Loop Test Report LABEL Attainable net data rate Actual Aggregate Tx Power Band Status LATN SATN SNRM Sub-Carrier Status Items Direction DESCRIPTION The is the maximum transmission data rate for this line. This is the total amount of transmission output power for this line. The fields in this section display the status for upstream bands 0, 1, 2, 3 (U0, U1, U2, U3) and downstream bands 1, 2, 3 (D1, D2, D3). This field displays the line attenuation situation in each band. NA displays when the band is not used. This field displays the signal attenuation situation in each band. NA displays when the band is not used. This field displays signal-to-noise ratio margin in each band. NA displays when the band is not used. This section allows you to select the criteria and display you the statistics in a raw data list or in a graph. Select Hlog-ps (Channel Transfer Function per sub-carrier) to see the line's capability against attenuation. Select QLN-ps (Quiet Line Noise per sub-carrier) to see the line's noise level. Select SNR-ps (Signal-to-Noise-Ratio per sub-carrier) to see the line's signal strength level by calculating the ratio between the received signal power and the received noise power for that sub-carrier. Select Hlin-ps to see the line's capability against attenuation. Select Downstream or Upstream for the direction. 346 VES1724-56 User's Guide
