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 to GSM establishing
and incoming call from GSM ringing.

The same applies to PCManager monitoring. A message announcing that SmartGate

is blocked is displayed during voice call establishing.

No voice call to GSM can be made during CSD data transmission and PC-FAX

connection.

Outgoing and incoming calls even to GSM can be made during GPRS connection.

The GPRS connection remains active during the whole call to GSM but no data can be
transmitted (SmartGate 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

SmartGate CD-ROM.

Caution! Since the GSM module is primarily used by the SmartGate central

processor for voice calls, use AT commands carefully. You might misconfigure the GSM
module thus making SmartGate inoperative. To solve most of these problems, switch
SmartGate off and on again to make the central processor execute full initialization of
the GSM module.
