Time zones
The time zones are used to allocate network providers depending on the time of
day. This means it is possible to take account of the fact that network provider 3 for
example is more cost effective at night than network provider 2
If the time at which a connection is set up is outside the defined time zones the call
is routed in accordance with the user configuration (without LCR function).
If the time indications of several time zones overlap, the time zone placed further
up in the table applies to the area of overlap:

Alternative Routing (Fallback Routing)
If the LCR function realizes that access to the network provider initially selected is
not possible, a call is routed to the alternative network provider and an event mes-
sage is generated (
LCR via alternative network provider
).
The LCR function recognizes that access to a network provider is not possible if,
•
if all the B channels in the selected route are busy or out of order,
•
routing via the primary network provider is barred in the network provider table,
•
the network signals to the PBX that the primary network provider is not availa-
ble (e.g. due to overloading).
