Least Cost Routing (LCR)
8 Least Cost Routing (LCR)
As of V2.0.2, Least Cost Routing (LCR) has been configured in such a way that it can be im-
plemented in different countries and for various functions. This feature is used to automate net-
work selection, a process of which the user is unaware.
The time and day of the week are not taken into account. Nor is a distinction made between the
type of calls (e.g. data connections) even if the call charge procedures vary.
Four different LCR types are made available in the system each of which can be selected within
system administration:
1. Single-stage LCR
2. Two-stage LCR
3. LCR for DICS dial-in procedure as of SW 2.1 (previously T-Net, Thyssen Telecom)
4. "Corporate Network" LCR (conversion table)
In the case of LCR types 1, 2 and 3, the assumption is made that the alternative network pro-
vider is always less expensive than the main network provider. For this reason, an exception
table which contains all the numbers not to be routed is compiled. This includes local calls, for
example. The exception table can comprise up to 50 numbers each with max. 7 digits.
