38DHB0002UKDJ – Issue 3 (12/00)
ARS analyses the leading digits of all on switch dialling (and incoming DDI digits)
for a match against a series of stored strings. If a match exists, the call then follows
the routing instructions stored with the string. If no match exists, the INDeX sends
the dialling on-switch for matching against a directory number.
String analysis distinguishes between strings which share the same leading digits,
e.g. 9010 and 901. ARS only confirms a match after entry of the first non-matching
digit.
– Example : Suppose ARS contains routing instructions for the strings 12,
123 and 1234. If the user dials 12, ARS take no action as there are still
possible matches other than just 12. Only if the next digit dialled is not 3
does ARS applies the instructions set for the string 12.
ARS ignores any ∗ and # symbols inserted into dialling unless there is a specific
string also containing the ∗ or # symbols:
– Example : Dialling a number starting 01∗0 follows the same routing as a
number starting 010 unless a ARS string for 01∗0 exists.
Routes from string analysis :
– Apply on switch translation.
– Use route list.
– Send untranslated over network.
– Prefix with network node number.
– Use time analysis.
– Apply translation over network.
– Use plan based analysis.
To add or edit a string :
1. From the Administration menu, select Automatic Route Selection and then
String Analysis.
2. To edit an existing string either select Display another string and enter the
string required or use the left and right cursor keys to move through the strings.
Select String processing and select the string process required.
3. To add a new string select Insert string and enter the string required. From the
sub-menu that appears select the routing required for numbers that match the
string.
4. To delete the currently displayed string, select Delete string.
