line to the monitoring station. For proper operation, define the parameters
described below.
7.7.1.
Phone line settings
7.7.1.1.
Use external phone line
If this function has been chosen (Activation) the communicator will be cooperating
with PSTN line. This way data transmission is possible from an alarm control panel
with two ways: via GSM / LTE link and standard telephone line.
7.7.1.2.
Disconnect external phone when server connected
If enabled, PSTN line will be disconnected from T1-R1 port when connection with the
server is established. If events registered by the alarm control panel are supposed to
be sent by GSM / LTE, this option can be used to separate external line from the alarm
control panel.
7.7.1.3.
Minimal time of external phone line voltage absence
If transmission with two ways follows, it is necessary that operator of monitoring
system received information on access to an external telephone line. Choice of this
option will result in voltage drop on telephone line (longer that defined minimal time
of decay) that will be signalized with an adequate message sent via GSM / LTE.
Note:
The communicator will simulate a telephone line in these cases:
o
A PSTN line is not connected
o
A PSTN line is connected but has not been activated.
