6.1.1.2.
GPRS test period
At a pre-defined interval the equipment sends “Test” signal that informs the
monitoring station that the device is operating. In that box, you can determine at
what interval defined in seconds the message will be sent.
6.1.1.3.
SMS mode after a number of unsuccessful attempts
Here you define the number of attempts to connect with the server. If during the
attempts no connection is established, after they terminate, the device will switch into
SMS mode. In this mode the equipment still attempts to connect with the server, at
an interval defined in item 6.1.3.3.
6.1.1.4.
SMS test period
The function is the same as for GPRS. It refers to the situation of any problems with
GPRS transmission, when the equipment automatically switches into SMS mode (it
also refers to the operation mode via SMS only). Sending a test SMS message as
often as in case of GPRS transmission is usually undesirable. That parameter allows
significant extension of interval between tests (time in minutes) or disabling that
option.
6.1.1.5.
Telephone number of a server
If to the server application (e.g. OSM.2007) a GSM modem is connected, here you
have to enter its number. SMS messages will be sent to this number in case the
equipment encounters problems with GPRS transmission.
In case the box remains empty or 0 is entered, the equipment will operate in GPRS
mode only.
NOTE: This box will be inactive in case the GPRS operation mode
of the equipment was defined.
6.1.1.6.
Send SMS events immediately
In case the GPRS connection is lost, information on upcoming events will be sent by
SMS immediately, even in case the equipment has not switched to SMS mode yet.
6.1.2.
Access Point Name
6.1.2.1.
APN
The parameter depends on GSM network operator whose GPRS service will be used.
It defines the name of access point to GPRS network. There is a possibility to obtain a
private access point. In this case its name will be given by a particular GSM network
operator.
