automatic PSTN fallback mechanism. A file may be empty if there have been no 
blocks or unblocks of any line pools, and if monitoring for any of the line pools 
was never started. A new log file is created every time the service is started.
Make sure that QoS monitoring is enabled for the line pool of interest through the 
Properties dialog box under the Quality of Service tab in Configuration Manager.
To view the file, in the Windows NT Explorer, find the log file directory and 
double- click the appropriate file qos_ yyyymmdd_ hhmmss. log.
Each record in the QoS file is 65 bytes long and contains information about the 
quality of service for one line pool at the time that the automatic PSTN fallback 
mechanism blocked or unblocked that line pool. Data is collected for four fields in 
each record. These records are detailed in the following chart. Note that:
A record ends with a new line (two bytes, a carriage return, and a line feed 
character).
The data is left-justified and padded with blanks. 
When QoS monitoring is enabled, the DEFINITY ECS application makes the 
information available to the Windows NT Performance Monitor.
To view QoS statistics in the Windows NT Performance Monitor:
