13 ATM tests
The following ATM tests can only be performed on an ADSL interface. Other interfaces
such as VDSL or Ethernet are not based on ATM.
13.1 VPI/VCI scan
In VPI/VCI scan, ARGUS checks which VPI/VCI combinations are active on the test
access. ARGUS transmits a test packet for all possible VPI/VCI and waits for a response
packet.
The following parameters must be saved in the profile for the VPI/VCI scan (when the xDSL
connection is already established, the connection parameters, e.g. ADSL mode and target
value, are locked).
Protocol-independent parameters:
The opening of test parameters is described in the chapter "Configuring accesses", see
page 30.
