4 Routing Elements

The role of routing elements is to route and distribute internal, incoming and out-
going calls to destinations. From the system's viewpoint a destination is an inter-
face (e.g. network interface or user-network interface). In this context user groups
or subscriber configurations are also routing elements, not destinations.
The settings allocated to a routing element are carried out in the system configu-
ration. This chapter describes the individual routing elements; the interplay
between the routing elements is described in "Call Routing", Page 2.115.
Fig. 2.28 shows how all the routing elements relate to one another:
[1] Routing via the numbering plan to one of the elements. Applies only to calls from the permanent net-
work PISN (see Page 2.126)
[2] Routing via a transit route (see Page 2.193) or as [1]. Applies only to calls from the permanent network
PISN
[3] Does not apply to calls from the analogue network
