46 Matrix SETU ATA211G System Manual

The Mobile Network Selection feature of SETU ATA211G enables you to select the GSM network of your

choice, either automatically or manually. At Power On, ATA211G will automatically locate and register

the SIM with the Network that supports the SIM card installed in it. If the SIM fails to register, it will restart

the process of network selection on the expiry of the Network Registration Retry Timer.

• Automatic: Select this option if you want the system to select the GSM network automatically. This will

available networks.

• Manual: Select this option if you want to select the GSM network manually. This will allow you to get

your SIM registered with the desired network operator available in that region.

If you select the Mobile Network Selection as Manual, assign priorities to the preferred netwok

operators for the registration of the Mobile port in the fields Priority 1 to Priority 9.

Enter Network Operator Codes (MCC and MNC) in the fields Priority 1 to Priority 9.

In these fields, Network Operator Codes (MCC and MNC) are configured according to their priority. So,

at every Power on, ATA211G will send a request for available GSM Network Operators, who in turn will

respond to the request with a list of available Network Operator Codes. ATA211G will match the

available Network Operator Codes with those configured in the fields Priority 1 to Priority 9 and select

the Network Operator which best suits your requirement in order of priority. See “Mobile Network

Selection”.

4. In the Band field, select the GSM frequency band supported by your service provider in your country.

ATA211G supports four major GSM frequency bands: GSM 850, EGSM 900, DCS 1800 and PCS 1900

mhz. Default: 900 + 1800 mhz.

If band selection is changed, it will be effective only after ATA211G restarts.

5. In Transmit Gain field, set the Transmitting Gain of the RF Signal to optimum level by selecting one out of

the five different levels: Very Low, Low, Normal, High and Very High. Default: Normal.

6. In Receive Gain field, set the Receiving Gain of the RF Signal to optimum level by selecting one out of the

five different levels: Very Low, Low, Normal, High and Very High. Default: Normal.

7. In SIM PIN field, enter the unique SIM PIN for the Mobile port of your ATA211G. The SIM PIN you enter

here must be of 4 minimum and 8 digits maximum. Default: 1234.

SIM PIN is a security feature used by the GSM network. If this feature is enabled on the SIM Card, the

network asks the system for the SIM PIN at every power ON. If the SIM PIN you have programmed here

matches with the one stored in the network, the network will mark ATA as present on the network.

8. In DTMF ON Time field, select the appropriate DTMF On time for sending DTMF digits. The DTMF On

Time is the time for which the DTMF digit which is to be out dialed remains ON. Valid range: 50 to 200

milliseconds. Default: 100 milliseconds.

9. In DTMF OFF Time field, select the appropriate DTMF OFF time as the time gap between two DTMF

digits. This can be set between 20 to 200 milliseconds. Default: 100 milliseconds.

10. In DTMF Level field, DTMF Level signifies with what magnitude (level/amplitude) the DTMF digits should

be out dialed. This can be set between 0 dB to -10.5 dB. Default: -6 dB.
