PBX Connection
Advantages and Disadvantages
PBX connection is the cheapest solution for places where a PBX is installed and a free
PBX line is available. Moreover, the
operational costs are zero if there is a 2N Lift1
®
well- trained staff continuously present in the building and is programmed 2N Lift1
®
for exclusive connection with them.
To ensure that shall make successful outgoing calls (i.e. via PSTN), follow 2N Lift1
®
the instructions below:
Make sure that the line to be used has the required authorisation (use a standard
phone to check whether outgoing calls to the defined numbers can be made via
this line).
Complete the PSTN access prefix while programming (zero as a rule) or set a
direct PSTN line seizure.
Identify the line (extension) and type of incoming connection (dial-in, DISA,
operator) and configure the PBX to allow for incoming
calls at night 2N Lift1
®
too (i.e. without operator).
Set the required authorisation for the extension to be used for calling to a mobile
network (GSM).
Make an arrangement with the PBX owner as to operation financing (the
2N
®
outgoing calls are at the owner's expense). Lift1
Caution
Check the type of PBX power outage protection because non-backed-up
PBXs transfer some of their lines directly to PSTN lines in the event of
would call other destinations if a prefix is power failure and 2N Lift1
®
used in this case! Refer to the Tips below for solution.
Tip
Operation financing can be solved by calling the "green lines" (prefix
0800).
The so-called automatic PSTN seizure (requiring no dial-in) is a practical
solution because being connected directly to a PSTN line during power
, will always call the right number. outage 2N Lift1
