5.16.1.2. Service Information 
- The digits dialed by the subscriber can be manipulated as a function of the route selected (LCR dial rules).
- The search for an idle circuit only takes place once during the call setup. However, a circuit is not seized until after a complete check of the dial plan.
- An additional alternative route can also be added to a route in LCR.
- For the primary path, the route with the shortest/least expensive connection should be established (direct connection).
- Restriction: LCR is only operable when the end partners of
the standard route are analog/digital stations or analog/digital CO trunk
circuits. Functional terminals and analog interface circuits, special
equipment (VMX, VMS, paging, etc.) and COs (as A or C stations in consultation)
are not supported.
