Aastra Intelligent Net:
In an AIN the nodes may be spread over different regions or even coun-
tries. Some settings do not apply throughout the system but only to one
region. A region is assigned to one or more AIN nodes. An region can also
be assigned for each trunk group. The trunk group allocation takes prior-
ity over the node-specific allocation.
The trunk group relevant settings for an region are:
– CLIP / CLIR (prefixes and codes)
– Call logging (call charge information)
– Flash time vis-à-vis the exchange
– Pulse dialling times vis-à-vis the exchange
– Country (country-specific, non-configurable parameters such as ISDN
protocol adaptations, line attenuations, etc.)
