Instant Alert Interfaces
There are three types of interface that can be used with Instant Alert.
GSM interface
GSM (Global System for Mobile Communications) is a standard to describe the protocols for second-generation digital cellular networks used by mobile devices.
A GSM modem is a specialized type of modem which accepts a SIM card (required for successful Instant Alert operation), and operates over a subscription to a mobile operator, just like a cell phone. When a GSM modem is connected to a computer, this allows the computer to use the GSM modem to communicate over the mobile network.
Attaching a GSM data terminal to the device on which Instant Alert is installed, allows SMS messages and email to be sent (as an action) from the Enterprise Server. The message can be sent to nominated contacts held in the Instant Alert Address Book.
NPort interface
A NPort device is a small data communications device that allows control of RS-232 serial devices over a TCP/IP-based Ethernet and can be used as an interface between multiple GSM devices and a server.
Most NPort interfaces support Simple Network Management Protocol (SNMP), which can be used to send trap messages automatically to the SNMP manager when user-defined errors are encountered.
SMTP interface
Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (email) transmission.
