3.6. ATM Generate Traffic 
Through the test ATM GENERATE TRAFFIC, the device can simulate several ATM 
traffic conditions in order to check the behaviour of the line as the traffic conditions 
change. This kind of  test is more exhaustive instead the simple ATM PING. 
D2061 is able to generate different types of traffic such as OAM F4 and F5 
maintenance cells both End-to-End and Segment, but also predefined packets 
already encapsulated at AAL5 level.   
Among the test results provided, statistic results like CLR (Cell Loss Ratio) are 
displayed as well as the throughput regarding transmitted and received cells. Such 
statistic is only indicative and it cannot represent the absolute maximum value 
available on the network. 
3.6.1.  Setting up ATM Generate Traffic test 
Define the following parameters to perform the test: 
Cell type: Select the type of traffic to simulate: 
•  F5 end to end, OAM F5 cell type used for controlling the entire connection 
(end to end).  
•  F5 segment, OAM F5 cell type used for controlling a single segment of the 
connection. 
•  F4 end to end, OAM F4 cell type used for controlling the entire connection 
(terminal - exchange). 
•  F4 segment, OAM F4 cell type used for controlling a single segment of the 
connection (terminal - exchange). 
•  AAL5 test, in order to send ATM cells encapsulated at level AAL5, used to 
control the line quality at AAL5 level. 
VPI: Virtual Path Identifier, default value is 8, on which flows the required traffic. 
VCI: Virtual Channel Identifier, default value is 35, on which flows the required traffic.
