Chapter 6. Further information about the Easy2S
operation
6.1 Primary and secondary communication channel
The
Easy2S
®
is capable of signaling the incoming events to two communication channels to
the remote dispatcher centre, via cellular network and by a GSM voice call.
The two channels can be enabled or disabled independently from each other. When all the
two channel is enabled, then the cellular signaling has priority and the voice call is activated
only in case of cellular communication and transmission failure. If both channels are disabled,
signaling and life sending are inactive.
6.2 Using the secondary channel
Two server can be configured for transmitting the signals, but only for one server will be
transmitted the data. The other server will be used as backup. The order of the primary and
secondary server operation can be defined by the
SFUNCT
parameter. The device switches
from the primary to the secondary server when the primary server cannot transmit data. If
the secondary server will successfully receiving the data, then the data will be still sent for
more 5 seconds to this server. Every signal transmitting will reset the counter of this time limit.
When the timeout spent it will switch back to the primary server.
The sending is successful, when a handshake reply is received back from the server within 6
seconds after the device sent.
Transmitting options in case of defining multiply IP addresses:
Signaling to 2 IP addresses (e.g. Server1: remote dispatcher centre which replies ACK
response; Server2: server, no ACK response).
Use cases:
•
It will sending only for the primary server (
GPRSEN
enabled
,
SERVER1
configured,
PORT1
configured)
