GSM/GPRS Module
During the setup of GPRS connections the MR2110 will attempt to make a connection to the specified APN a number of times before it will assume that there is a problem with the GSM/GPRS module.
By default, after 10 unsuccessful attempts to bring up a PPP link to the specified APN the GSM/GPRS module will be rebooted, note that only this module and not the MR2110 unit is power-cycled.
In addition to this the MR2110 will check the status of the GSM/GPRS module every 10 seconds to gather information about signal strength, attachment status etc. In the event that the module cannot be contacted 30 consecutive times it will be rebooted.
In each event the process of SIM registration and GPRS attachment will be retried which will be shown by the LEDs as normal
