Positioning

Applications range from very small offices and branches (Aastra 415) to small and
medium-sized companies (Aastra 430).
The diagram below shows the Aastra 400 communication servers with their expan-
sion capacity for IP system phones.

Networking Possibilities

Aastra 400 communication servers at different company locations, even beyond
national borders, can be linked together to form an enterprise-wide private com-
munication network with a common numbering plan. The following networking
types are possible:
Aastra Intelligent Net (AIN)
In an AINseveral communication servers of the Aastra 400 series can be connected
up to form a homogeneous communication system. The single systems are con-
nected with one another via the IP network, thereby forming the nodes of the over-
all AIN system One node acts as the Master and controls the other (satellite) nodes.
All the features are then available at all the nodes.
No call charges are incurred as the internal voice traffic between locations is routed
via the system's own data network. All the AIN nodes are configured and set up
centrally via the Master.
If a node is isolated from the rest of the AIN by an interruption in the IP connection,
it restarts with an emergency configuration after a set amount of time. The connec-
tions are then routed to the public network via local links, for example with ISDN or
SIP connections, until contact with the AIN is restored.
