Use external phone line
8.6.1.
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 LTE/HSPA+ link and standard telephone line.
Disconnect external phone when server connected
8.6.2.
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 LTE/HSPA+, this option can be used to separate external line from the
alarm control panel.
Minimal time of external phone line voltage absence
8.6.3.
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 LTE/HSPA+.
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 – option from clause 8.6.1
Use external phone line
Options from clause 8.6.1 and 1 are active and voltage on terminals TIP-RING
decreased below 8V.
Report off-hook time longer than
8.6.4.
This option is being used if in configuration “PSTN line – EPX400 – Alarm Control
Panel” there are not other telecommunication devices. If such device will be
connected and telephone number will be dialled (and a call will follow) after expiry
defined time limit (counted since conclusion of last digit dialling) the communicator
