functions are analogous to the both telephone numbers that may be saved in the
device memory.
DTMF phone number
8.6.1.1.
This is a number that has been saved in memory of an alarm control panel. If the
panel is to transmit information on an event it shall dialled this number. Transmission
of this information via LTE/HSPA+ will be possible if this number will be identical as a
number entered into the communicator.
Handshake delay
8.6.1.2.
This defines time after which a communicator generates confirmation to an alarm
control panel for correct phone number dial. Default setting is 2.0 sec. European
Standard determines this value at 0.5 to 12.5 sec.
Protocol
8.6.1.3.
Select protocol of data transmission used by an alarm control panel and that is
acceptable for monitoring station. Available options: ContactID and SIA.
Note:
1) For all protocols you may use following options:
o
[Enable SMS sending] which means that in case of no LTE/HSPA+
connection, data will be sent via SMS (if this mode will be accessible).
o
[Don’t transmit data when external phone line is available] which means
that when the external PSTN line is available then it will be used during
transmission from the control panel.
2) [Disable CRC checking] option may be used for ContactID format. Some control
panel generate improper messages regarding a control sum for transmitted data, the
device is not able to confirm collection of data, and as a result the panel tries to send
them again (until execution of all determined trials). Select this option to avoid the
above mentioned.
