FEATURE DEFINITIONS
CID
Contact ID reporting protocol.
CSD
Circuit Switched Data. This is the communication used to upload/download data. It is similar
to a modem but it is wireless and built in to the NX-7002 (see locations 0, 162 segment 10 and
location 168).
GPRS
General Packet Radio Service. A global standard for wireless communications with a
maximum speed of 115 kilobits per second. It supports a range of bandwidths and can
transmit and receive both small bursts and large amounts of data.
GSM
Global System for Mobile Communications. A global standard for wireless communications
with a maximum speed of 9.6 kilobits per second. It supports narrowband Time Division
Multiple Access (TDMA).
Non transparent mode
An intermediate modem is used on the network to transfer data from one modem to another
(see location 0 segment 1).
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 (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-7002 (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-7002 will act as a backup for the control
panel (see location 25 and location 162 segment 3).
