Testing the connection
For easier diagnosis of connection problems it is possible to display extended result codes for incom-
ing call indication. In order to do this the following steps are necessary:
•
Activate result codes: Enter „ATQ0“, Modem reply: OK.
•
Activate extended result codes: „AT+CRC=1“, Modem reply: OK. („AT+CRC=0“ switches the ex-
tended codes off)
•
Call UniMod GSM-3 via data service (use appropriate telephone number). Watch incoming call
using terminal program. Possible messages:
+CRING: REL ASYNC incoming call has been correctly transmitted. That’s OK.
+CRING: VOICE
incoming call has been transmitted via „voice“ mode.
Call rejected by modem.
+CRING: FAX
incoming call has been transmitted via „fax“ mode.
Call rejected by modem.
