Alarm sending channels
In this menu, channels for sending alarms and events to the central monitoring
station of the security company are selected. Hub 2 Plus can send alarms and
events to the central monitoring station via Ethernet and EDGE. We
recommend that you use all communication channels at once — this will
increase the transmission reliability and secure against failures on the
telecom operators' side.

GSM — enables event and alarm transmission via the mobile Internet.
Periodic Test Report — if enabled, the hub sends test reports with a given
period to the CMS (Central Monitoring Station) for additional monitoring of
object connection.
Monitoring Station Ping Interval — sets the period for sending test
messages: from 1 minute to 24 hours.

encryption is used.
Encryption — if enabled, events and alarms transmitted to the central
monitoring station in SIA format are encrypted.

match the value on the Central Monitoring Station.
