10 ATM Tests
The following ATM tests can only be performed on an ADSL or SHDSL interface in the
"ATM“ access mode. Other interfaces, such as VDSL, Ethernet or SHDSL in the "EFM“
access mode, do not use ATM technology.
10.1 VPI / VCI Scan
In a VPI/VCI scan, the ARGUS checks which VPI/ VCI combinations are active on the
access under test: The ARGUS will send a test packet for each of the possible VPI / VCI
combinations and wait for a packet in response.
The following parameters, which are stored in a profile, are required to perform a VPI/VCI
Scan (if a xDSL connection has already been setup, the connection parameters, e.g. the
ADSL mode and the target value, are blocked):
Protocol-independent parameters:
