7.6. Combination of COM Traffic with Voice Calls
As already mentioned, SMS transmission can be made even during telephone calls.
The SMS program is only blocked temporarily during outgoing call establishing and
incoming call ringing.
The same applies to PCManager monitoring. A message announcing that EasyGate
is blocked is displayed during voice call establishing.
No voice call can be made during CSD data transmission and PC-FAX connection.
Outgoing and incoming calls can be made during GPRS connection. The GPRS
connection remains active during the whole call but no data can be transmitted
(EasyGate is a GPRS terminal of class B). Once the call is terminated, data
transmission is recovered immediately.
7.7. List of Supported AT Commands
There are original files related to SIEMENS GSM modules in the PDF format on the
EasyGate CD-ROM.
Caution! Since the GSM module is primarily used by the EasyGate central processor
for voice calls, use AT commands carefully. You might misconfigure the GSM module
thus making EasyGate inoperative. To solve most of these problems, switch EasyGate
off and on again to make the central processor execute full initialization of the GSM
module.
Do not use particularly:
