Operator
The network operator for the SIM card.
Polling
Polling is the process by which the system reports periodically to a receiver to say it is still
alive. It works in conjunction with TCP/IP reporting only. Polling is more frequent than a
daily test call but less frequent than continuous monitoring. If you configure a very short
polling time, polling occurs very frequently and can generate large quantities of data.
When setting the polling time, you should consider the speed of the GPRS network and
the cost of data transmission. Assuming perfect conditions on a typical GPRS network,
the following number of bytes are sent over GPRS. For polling approximately 0.5Kb and
for event reporting approximately 0.4Kb + 0.2Kb per event (see location 0, segment 3 and
location 162 segment 6).
PUK code
Personal Unblocking Key. The code to use to unblock the SIM card. The SIM card can
block when an incorrect SIM PIN is entered repeatedly.
Report control
A block of reporting data that contains configurations to format selected events into one
or more messages according to pre-configured settings and send them to specified
destinations (see location 1).
RSSI
Received Signal Strength Indicator. This indicates the field signal strength of the NX-
7002N (see location 172 and location 162 segment 11 and 12).
Secondary reporting
The means of reporting events that the control panel fails to report. When secondary
reporting is enabled, the report control set in the NX-7002N will act as a backup for the
control panel (see location 25 and location 162 segment 3).
Up/download call-back from audio
A CSD communication (Circuit Switched Data) or data communication is the
communication used to upload/download via the NX-7002N. If enabled in location 200 an
Upload/Download call-back session may be initiated simply by calling the audio number
of the SIM card in the NX-7002N and hanging up after 2 to 10 seconds. The NX-7002N
will automatically call back to the download PC (set for ”Wait for call-back GSM”) to start
an Upload/Download session. In this way up/download is available while it saves the
extra cost of having a CSD or data number from the provider.

PUK code
SMS
Short Message Service. SMS is a service for sending short text messages to mobile
phones (see locations 1, 145, 163, 164, 167).
Transparent mode
Data is transferred directly from one modem to another modem (see location 0 segment
1).
