Terminals with a separate direct dialling plan down circuit from an Aastra 400 com-
munication server can also be addressed from the public or private leased-line.
From a routing technology viewpoint this corresponds to the situation "Routing a
call from the public / private network to the PISN" (see also the descriptions as of
page 257).
An BRI-S interface (P-P or P-MP) can be used as the network interface.

Least Cost Routing (LCR)

Nowadays users usually have several service providers at their disposal to rely on
for routing their calls. To ensure that calls are routed as cost effectively as possible,
it make sense to select the service provider according to the call destination (e.g. to
use a different service provider for long-distance calls compared with local calls).
A service provider will either have his own network or a licence agreement with an-
other network provider. A private leased-line network as defined for the LCR func-
tion is a service provider with special characteristics.
In this chapter the term network provider will be used for both network providers
and service providers.

Direct or indirect Selection of the Network Provider

The network provider can be selected either manually for each call or automatically
using the LCR function.
