• The number analysis checks the first column for
a matching destination number and uses the re-
lated Destination Number Group for carrier sel-
ection.
Attention!
The Public Destination Number Table and the
first column of the Destination Number Cross
Reference Table have to use the same Predigits,
e.g. the Predigits for PTT.
This Destination Number Cross Reference Table tells
us:
• The Predigits „0“ is assigned to the trunk lines
that access the carrier „PTT“. Therefore, we
have to use the same Predigits for the Public De-
stination Number Table. (Our example uses
PTT’s destination numbers for reference purpo-
ses. The carrier „Ferrari“ uses the same Predi-
gits, because it is accessed via „PTT“)
• The carrier „tie line Vie“ uses the Predigits
„9999“. [1015 Predigits for number analysis]
Example of the Destination Number Cross Reference Table:
• The destination number „022281100…“ is rela-
ted to the Destination Number Group „249“.
• The same destination may be reached by en-
tering „022281100…“ or by seizing the tie line
„Vie“.
• Bill’s telephone number (United States „001…“)
does not match with the destination numbers in
the first column. The number analysis has to
check the Public Destination Number Table for
„001…“.
