ANT-20/ANT-20E Broadband Analyzer/GeneratorApplication Guide A-25Tip: To stop the scan click the icon button of the toolbar again or click “Start” in the “Scan”menu again.A scan can only be started or a test traffic can be generated, when no other measurements thatare started from the Application Manager are in progress. No other measurements can bestarted or a test traffic can be generated, while a scan is in progress.Table A-3 Result list header for “Activity” scan type3.4.2 Analyzing the AAL types of active ATM channelsDetect and analyze the AAL types in the detected ATM channels (Fig. A-30, Page A-24).To start the analysis⇒ Click the above icon button of the toolbar or click the item “AAL Type” in the “Analyse” menu.A bargraph display appears indicating the progress of the analysis.Fig. A-31 Analysis of AAL typesIf a large number of channels are listed in the results window, AAL analysis may take a very longtime. You can interrupt the analysis at any time using the “Cancel” button. All the channelslisted, regardless of AAL status, are checked during an AAL analysis.Column MeaningNo. Sequence number to assist orientation in the listVPI Virtual Path Identifier. Displayed as a decimal number.VCI Virtual Channel Identifier. Displayed as a decimal number.CI-BW Congestion Indicator Bandwidth: Proportion of cells with Congestion Indication (CI) bitset. The displayed percentage is determined over the entire duration of the scan.CLP1-BW Cell Loss Priority 1 Bandwidth: Proportion of cells with Cell Loss Priority (CLP) bit set.The displayed percentage is determined over the entire duration of the scan.AvBW Average Bandwidth of the channel in Mbit/s. The displayed value is determined overthe entire duration of the scan. All user and OAM cells are included in the calculation.CuBW Current Bandwidth or channel load in Mbit/s. The displayed value is the average for thelast seconds. All user and OAM cells are included in the calculation.AAL attributes
