Connection via PBX (Private Branch Exchange)
This is the least-cost solution where a PBX and an unused PBX line are available.
PBX line requirements:
The PBX to be used must work reliably even in the case of power outage. Large
PBXs are mostly equipped with a back-up power supply, smaller PBXs usually use
PSTN line redirection in the event of power failure. Consult the problem with the
technician responsible for your PBX. An error during power outage may result in
calling an undesired station. 2N Lift8

Relevant call access rights have to be assigned to the PBX line to be used (use a
standard telephone set to check whether the line can make outgoing calls to all
the required numbers).
While programming, enter the necessary PSTN code (typically a zero), or
(preferably) make the PBX not require a prefix (so-called automatic connection to
the provider's telephone line).
To make the control room – lift calls, you have to know the extension number
and how to get through to it (dial-in, DISA, operator).
The control room – lift connection may not depend on the operator’s presence;
no call forwarding to a fax/answering machine in the night mode is allowed, etc.
Other recommendations:
Make an agreement with the PBX owner regarding operating costs (2N Lift8

outgoing calls are billed at the owner‘s expense with the exception of free calls
via “green lines”).
GSM
This is used in particular where no PSTN line is available.
Recommendation
In places with a poor signal quality find an appropriate place or use a special

If a prepaid SIM card is used, make sure that the credit is monitored and
topped up in time.
