Operating System
The operating system of the modem is responsible for the following functions:
•
Drives the modem via an AT Command interface over a serial port
•
Real Time Clock (RTC) with calendar
•
Dual-mode GSM/LTE or UMTS (WCDMA)/LTE operation
Note:
The GL7x00 is not programmable.
1.5.3.
Last Gasp
Additionally, the GL7600 supports Last Gasp which allows the modem to send an emergency
message (either an SMS or a UDP package) to the server when the main power is unexpectedly cut.
It makes use of the modem’s internally stored emergency power to send a message after a sudden
power outage.
For Last Gasp configuration information, refer to 5 Last Gasp Configuration.
