Chapter 2 – AT Commands

Command:

+GCI

Country/Region of Installation

Description:

 

This extended syntax command selects and indicates the region/country of installation for

 

 

the modem. The parameter selects the settings for any operational parameters that need

 

 

to be adjusted for national regulations or telephone networks.

 

 

Syntax: +GCI=<region_code>Defined Values: <region_code>Example: Euro/Nam = B5.

 

 

For a list of regions/countries approvals and codes, see the Multi-Tech Web site at:

 

 

http://www.multitech.com/PRODUCTS/Info/approvals

Default:

 

If the modem is specified for use in only one country, the country code is the default.

 

 

Otherwise, the default is defined by the OEM. The factory default is B5.

Report Commands:

+GCI?

Reports current or selected values.

 

 

+GCI=?

Reports supported range of parameter values.

Command:

+MS= Modulation Selection

 

Values & Default:

See description.

 

 

Description:

 

This extended-format command selects modulation and, optionally, enables or disables

 

 

automode, specifies the lowest and highest connection rates, selects µ-Law or A-Law

 

 

codec type, and specifies the highest transmit rate using one to five subparameters.

 

 

The command format is:

 

 

 

+MS=[+MS=[<carrier>[,<automode>[,<min_TX_rate>[,<max_TX_rate>[,min_RX_rate>[,<max_RX_rate>]]]]]]

 

 

Subparameters that are not entered retain their current value. Commas separate optional

 

 

subparameters and should be inserted to skip a subparameter. Example: +MS=,0,<CR>

 

 

disables automode and keeps all other settings at their current values.

Subparameters:

 

mod – A decimal number that specifies the preferred modulation (automode enabled) or

 

 

the modulation to use in originating or answering a connection (auto-mode disabled).

Note: Some <carrier> values may not be supported by certain model models.

automode – An optional numeric value that enables or disables automatic modulation negotiation using V.8bis/V.8 or V.32bis Annex A. The options are:

0 = Disables automode

1 = Enables automode (default)

<min_rx_rate> and <max_rx_rate>

Numeric values which specify the lowest (<min_rx_rate>) and highest

(<max_rx_rate>) rate at which the modem may establish a receive connection. May be used to condition distinct limits for the receive direction as distinct from the transmit direction. Values for this subparameter are decimal encoded, in units of bit/s. The possible values for each modulation are listed in the table above. Actual values will be limited to possible values corresponding to the entered <carrier> and fall-back <carrier> as determined during operation. (Default = lowest (<min_rx_rate>) and highest (<max_rx_rate>) rate supported by the selected carrier.)

<min_tx_rate> and <max_tx_rate>

Numeric values which specify the lowest (<min_tx_rate>) and highest

(<max_tx_rate>) rate at which the modem may establish a transmit connection. Non- zero values for this subparameter are decimal encoded, in units of bit/s. The possible values for each modulation are listed in the table above. Actual values will be limited to possible values corresponding to the entered <carrier> and fall-back <carrier> as determined during operation. (Default = lowest (<min_tx_rate>) and highest (<max_tx_rate>) rate supported by the selected carrier.)
