Programming ARS can seem complicated. A controlled and methodical approach,
with all stages planned on paper first simplifies the task. It also allows you to keep
the routing simple and understandable.
Plan First :
– Work Out Switch Routes :
Determine which call routes from the INDeX are available, e.g. PSTN, PSTN
alternate carrier, network nodes, trunk groups, etc.
– Work Out Switch Dialling :
Determine what numbers dialled on the INDeX require routing other than 'on-
switch as dialled'. These are the strings that must be in String Analysis.
– Work Out Translations :
Matching the switch routes and the switch dialling to those routes determines
the digit translations are required.
– Plan String Routes :
Determine the factors that control which strings use which routes, i.e.. time,
who's dialling, several routes to one place, etc. and relate these to ARS time
and plan based processing.
– Program from the bottom up :
A Route List cannot specify a Translation until that translation has been
programmed, similarly String Analysis cannot refer to a Route List until that
Route List has been programmed. You must program the ARS package from
the 'bottom-up', starting with the most basic elements (digit translations).
Additionally ARS cannot route any calls to a network node unless that node is
programmed into the network routing table (see page 33).
You can reset all the ARS settings back to their default values. After defaulting it is
still possible to make normal external calls.
To default the ARS settings :
1. From the Administration menu, select Automatic Route Selection.
2. Select Default ARS.
