Least Cost Routing (LCR)
Preconfiguration for UK:
This involves the most recent national Mercury exception table before implementation. Special
references are made to the two emergency numbers; the traditional "999" and the new EC stan-
dard "112".
The exception table can be configured and entries made or deleted as required. An option may
also be included which enables the system administrator to activate and deactivate the feature
"selecting the network provider" on a system-wide basis.
8.1 Single-stage LCR
All numbers are routed apart from those explicitly entered in an exception table, see Table 8-1
. In this type of LCR, the network provider desired is selected via a configurable prefix (e.g.
"132" in GBR) and the number then dialled. Selection takes place in the D-channel (for ISDN)
or as standard for analogue trunks.
The following configurations are necessary or possible for this type of LCR:
●
Prefix for selecting the network provider
●
Authorization code
