Since carrier 1055 appears in the carrier table, but area code 051 does not appear in the enabled
table of the area codes of this carrier , the switchboard prohibits the call (dissuasion tone at the
branch and outside line freed).
8th case: the branch dials 0689….
Since area code 06 does not appear in the blocking table, or in the enabled table either, the
switchboard allows the call on preferential carrier 00 (default: TELECOM ITALIA 1033).
Example 3: restrictive criterion (blocking table empty)

2nd case: the branch dials 0118….
