14.6.3
Smart Scan
The smart scan
is an scan evolution method and “smart” mode to check each single parameter of the checked
frequency: if during a scan, a single parameter of the scanned frequency is out-of-range the Wolf 2MS should decide to
remain more time (in seconds) on the checked frequency, in order to get the correct value, or exclude a false-positive
alarm.
Practical example: a typical case should be the decoding of the ODA service in RDS, or a PI Code, or any value
checked. If the decoding gives an “error” the Wolf 2MS can stay more seconds on this frequency, and wait in order to get
the correct value, and don’t generate an error (via snmp trap) that can overload the NMS system. In the real fact the
checked valued is correct, but sometimes due to a lot of unpredictable situation, this value should be considered as an
error.
