Dialling by Name
A PISN subscriber can dial any PISN subscribers by name, irrespective of region,
topology and protocol, if the PISN subscriber is explicitly listed by name in the
numbering plan of the source PINX.
Least Cost Routing (LCR)
The Least Cost Routing function (LCR) is used for special network functions such
as break-out or overflow (see "LCR Function", Page 2.157).
Overflow Routing
When a connection is setup the system checks the availability of the selected path.
If that path is not available due to overloading or due to a defect, the connection
is set up via an alternative path determined by the configuration (see "Testing
overflow Routing in the PISN", Page 2.199).
