7.3 Summary of all Unsolicited Result Codes (URC)
A URC is a report message sent from the ME to the TE. An unsolicited result code can either be deliv-
ered automatically when an event occurs or as a result of a query the ME received before. However, a
URC is not issued as a direct response to an executed AT command.
Typical URCs may be information about incoming calls, received SMS, changing temperature, status
of the battery etc. A summary of all URCs is listed below. For each of these messages, you can con-
figure the ME whether or not to send an unsolicited result code.
For the URC to be sent the ME activates its Ring Line (Logic "0"), i.e. the line goes active low.
