ESIM384 Installation and Configuration Manual v1.1
30.2. Communication
the system supports the following communication methods and protocols:
•
GPRS network – eGR100, Kronos, SIA IP protocol (ANSI/SIA DC-09-2007; configurable as encrypted and non-encrypted).
•
Voice calls (GSM audio channel) – Ademco Contact ID protocol.
•
CSD (Circuit Switched Data).
•
PStN (landline) – Ademco Contact ID protocol.
•
SMS – Cortex SMS format.
•
eLAN3-ALARM – eGR100, Kronos, SIA IP protocol (ANSI/SIA DC-09-2007; configurable as encrypted and non-encrypted).
Any communication method can be set as primary or backup connection. the user can set up to 5 backup connections in any sequence order.
Initially, the system communicates via primary connection with the monitoring station. By default, if the initial attempt to transmit data is
unsuccessful, the system will make additional attempts until the data is successfully delivered. If all attempts are unsuccessful, the system
will follow this pattern:
a) the system switches to the backup connection that follows in the sequence (presumably - Backup 1).
b) the system then attempts to transmit data by the backup connection.
c) If the initial attempt is unsuccessful, the system will make additional attempts until the data is successfully delivered.
d) If the system ends up with all unsuccessful attempts, it will switch to the next backup connection in the sequence (presumably - Back-
up 2) and will continue to operate as described in the previous steps. the connection is considered unsuccessful under the following
conditions:
•
GPRS network/eLAN3-ALARM – the system has not received the ACK data message from the monitoring station within 40 seconds.
•
Voice calls:
• The system has not received the “handshake” signal from the monitoring station within 20 seconds.
• The system has not received the “kissoff” signal from the monitoring station within 5 attempts each lasting 1 second.
•
CSD – the system has not received the ACK data message from the monitoring station within 35 seconds.
•
PStN:
• The system has not received the “handshake” signal from the monitoring station within 20 seconds.
• The system has not received the “kissoff” signal from the monitoring station within 5 attempts each lasting 1 second.
•
SMS – the system has not received the SMS delivery report from the SMSC (Short Message Service Center) within 45 seconds.
e) If one of the attempts is successful, the system will transmit all queued up data messages by this connection.
f) the system then returns to the primary connection and attempts to transmit the next data messages by primary connection.
g) If the system ends up with all unsuccessful attempts by all connections, the keypad will indicate system fault and the listed user may be
notified by SMS text message (by default - disabled), while the system will hold until the
Delay after last communication attempt
time
(by default – 1200 seconds) expires and will return to the primary connection afterwards. Once the repeated data message delivery
cycle has started, the system will skip the connections with disabled R
etry after delay
function (permanently enabled for IP commu-
nication methods - GPRS network and eLAN3-ALARM). In the event of successful data message delivery, the keypad will no longer
indicate system fault.
h) If a new data message, except test event (ping), is generated within the
Delay after last communication attempt
time-frame, the
system will immediately attempt to transmit it to the monitoring station, regardless of
Delay after last communication attempt
being
in progress.
