4. SOFTWARE INTERFACE

4.1 GENERAL

The operating functions of the g18 modem are implementedin the base unit into which the g18 is integrated. The g18 isa GSM900/1800/1900 Phase II+ device with GPRS capabil-ities.

The corresponding functions are implemented conformingto V.25ter, GSM07.07, and GSM07.05.

AT+C commands conforming to GSM07.07 and GSM07.05and a number of manufacturer-specific AT commands areavailable via the serial interface of the g18 for functionalityimplementation.

Commands are input via the operating functions of the baseunit. The base unit translates the operating functions into ATcommands and the g18 executes the requested action.

The V.25ter modem guidelines apply to the time sequence ofinterference commands. In accordance with these guide-lines, commands start with the string AT and end with acarriage return (<CR> or 0x0D). Commands are acknowl-edged with OK or ERROR. A command currently beingprocessed will be interrupted by each subsequent incomingcharacter, so the next command must not be sent until theacknowledgement has been received that the command hasbeen processed. If this does happen, the current commandwill be cancelled.

4.2 MODEM COMMUNICATION MODES

The g18 modem supports the following communicationsmodes: voice, data, SMS and fax.

4.2.1 Voice Communication

• Analog Audio: Analog audio communication is providedvia a standard analog headset such as the headset usedwith the StarTAC cellular phone. In this case, the controlsfor answering calls, dialing, and hanging up are providedby the AT command set interface. This mode is used if themodem is integrated into a handheld terminal thatsupports voice communications.

• Digital Audio: Digital audio is provided by the MotorolaProprietary DSC interface. This interface is used when anexternal handset, like that used in an automotive installa-tion, is used. In this case, the call controls are provided onthe handset. DSC handsets that support this interface aremanufactured by and available from Motorola. The ATcommand set can also be used to control calls. The DSCinterface is a Motorola proprietary feature that requireslicensing from Motorola. Please contact your Motorolarepresentative for more information.

4.2.1.1 Configuration Setup and Audio Routing in g18

Voice Connectivity

The g18 is an OEM data and voice module. Voice connec-tivity can be performed using two main channels: analogvoice and digital voice.

Note

The standards bodies regularly update thesestandards, therefore there is no guarantee thatthe commands supported by the g18 exactlyconform to the latest versions of these specifi-cations. Some commands listed in these stan-dards do not apply in the GSM environment.

Note

You should wait to receive OK before sendinga new AT command.

Software Interface

The audio route for the different devices is described in thefollowing table, where HF refers to the connected externalspeaker and microphone, and DHFA refers to the externalcar kit.

• Sidetone - Reduces the microphone audio input that isrouted to the selected speaker so that the people speakingwill hear themselves talking. This also creates a slightecho because the speaker sound then gets picked up againby the microphone and again output to the speaker, and soon. Echo suppress is designed to take care of this echo.

• Echo Suppress - Cancels a small amount of the outputsound picked up by the input device (suppresses theecho). It is designed to be used where there will be littleor no echo (for example, in a handset) rather than where

there will be a lot of echo (for example, in a hands-freedevice).

• Echo Cancel - Suppresses a large amount of the outputsound picked up by the input device (cancels all echo).

• Noise Suppress - Improves audio quality in all modes.

If the application uses the DSC bus, HF selection can beperformed via the new IP.

To activate the hands free mode, see the following table:

4.2.2 Data Communication

There are two modes in which to use the data port:

• GPRS: This mode is for package data communication.This mode starts from the command mode and after aninitialization of a PDP context the data sent from the DTEwill be over PPP. A GPRS wizard is available to do the

PDP connectivity (for PC applications). This is a veryeffective tool for transferring data at a high rate and onlywhen data is available, without the need to dial again.

• CSD - Circuit Switch Data: The default setting for theg18 is RS232 full flow control. In this mode, data, SMSand Fax class 1 are transferred using a full flow control(hardware flow control), Xon/Xoff or non-flow control.The main difference between this mode and the GPRSmode is the need to dial the desired number wheneverdata needs to be transferred.

4.2.3 SMS Communication

• Block mode: This is a binary SMS presentation. Anapplication SMS build is required for this mode.

• Text mode: This mode is not supported by the g18.

• PDU mode: This is the recommended mode for SMScommunications. Note that the PDU packet has acomplex structure, so careful examination of GSM 04.11and GSM 03.40 is required.

4.2.4 Fax Communication

Class 1: This is the basic set of fax commands that issupported by all types of fax machines. To support faxcommunication with g18, use WinFax in your computer.

Class 2: This mode is not supported by the g18.

4.3.7 Setting Up the g18 in CSD Mode

When a data call is received, the RI signal goes to ActiveLow for one second and then to Inactive High for fourseconds repeatedly, as shown below.

Figure 32. RI Waveform

When a data carrier is detected by the g18, it sets the DCDsignal to Active Low.

4.4 SENDING AND RECEIVING DATA IN DIFFERENT FLOW CONTROLS

4.4.1 Flow Control Set to Hardware Flow Control (FC)

4.4.1.1 Sending Data

When data is sent by the g18, the only dynamic signalsthrough the data transfer are TXD and CTS. The DTE deviceshould be kept at DTR ON.

TXD is used in order to transmit the data from the terminalto the g18, and CTS is used in order to control the data flow.When data is transferred too rapidly to the modem, at a ratewhich is greater than its transfer rate, and its buffers becomefull, the modem sets CTS to Inactive High, until it completesthe transfer.

When the modem is ready to accept more data, it sets theCTS signal to Active Low again.

Figure 34. g18 Sending Data Hardware Flow Control

4.4.1.2 Receiving Data

When data is received by the g18, the only dynamic signalduring the data transfer is RXD, with which the data is sentto the terminal. The DTE device should keep DTR ON. RTScan be used to alert the g18 that the DTE buffer is full.

Figure 35. g18 Receiving Data Hardware Flow Control

4.4.2 Flow Control - Flow Control Set to Xon/Xoff

The g18 should be configured to Xon/Xoff flow control,using AT&K4.

To return to the hardware flow control, use AT&K3.


When data is sent in this mode, it is transferred on the TXDline. The DTE device should keep DTR ON.

When data is transferred too rapidly to the modem, its buff-ers may become full, and the transmission cannot succeed.In this case, it sends an Xoff signal to the terminal on theRXD line.

When the modem has sent the data in the buffer and is readyto receive more data, it sends an Xon signal on the RXD line.

Note

The g18 does not support non-transparent CSDwith a baud rate of less than 4800 bps.

4.6 SENDING AN SMS

4.6.1 Sending an SMS in PDU Mode

For example:

AT+CMGS=19

>07914483056100F511000B914410927856F40000000541E1905804<0x1A>

will return +CMGS:000 after sending “ABCDE” to phonenumber 44-012-987-654 via the SMS center at 44-385-016-005.

The following ASCII string is the ASCII representation ofthe hexadecimal values that will be transmitted as a binarystring.

‘F’’4’ below means that the hexadecimal values 0xF and 0x4will be transmitted over the air. CMGS=19 is the length ofthe TPDU in octets, see below.

AT+CMGS=19

>07914483056100F511000B914410927856F40000000541E190F804<CTRL-Z>

07 = LENGTH OF SCA element including the TON/NPI

91 = TON/NPI,TON=9=Type of number, NPI=1=Number-ing Plan Identifier

4483056100F5 SCA =SERVICE CENTER ADDRESS(This means that the real phone number for the SCA is 44-385-016-005).

Explanation of phone number coding: One hexadecimaldigit for each phone number digit is used. Each pair of hexa-decimal digits is considered an octet (8 bit binary number).Then, the two hexadecimal digits are reversed in order toform a semi-octet. So, the phone digits 3, 8 will become 0x3,0x8, then 0x38, and then reversed to become 0x83. TheASCII characters ‘8’ and ‘3’, the string ‘83’ are then insertedinto the full ASCII string above. Since there is an oddnumber of digits, the last digit, 5, is placed in the lowernibble of the last octet and then its top nibble is filled with1s. This means that ‘5’ becomes 0x5, then 0x05, then 0xf5,and then ‘f5’, which are the last two characters in the ServiceCenter address.

Refer to ETSI 04.11 for more details.

Looking at the remainder of the message after the SCA, wefind the Transport Protocol Data Unit (TPDU). The TPDUcontains the destination device address (phone number), andthe user data or message. There are 38 characters, whichrepresent 19 octets, this being the length of the TPDU.

00 = PID Protocol ID

00 = DCS Data Coding Scheme

00 = VP Validity Period

05 = UDL User Data Length

41E190F804 = The user data ‘ABCDE’

Description of encoding the user data: The user data isencoded as GSM characters. The GSM character set is amethod of encoding 7 bit ASCII characters into 8 bitnumbers. GSM only supports 128 characters with ASCIIvalues 0x00 to 0x7f. Since these only need 7 bits to definethem, and the SMS message is transmitted as a series of 8-bitvalues, GSM uses a method of packing the series of 7 bitvalues into 8 bit octets. For example:

ABCDE is encoded as 41E190F804 as follows.

A B C D Ein ASCII hexadecimal is:0x41 0x42 0x43 0x44 0x45in 8 bit binary is:01000001 01000010 01000011 01000100 01000101

The most significant bit is truncated, resulting in a series ofseven bit values. The now unused most significant bit(s) arepacked with enough least significant bits from the followingvalue to make up eight bits.

This results in the string of eight-bit hexadecimal numbers0x41, 0xE1, 0x90, 0x58, 0x04. By continuing this process, astring of 160 ASCII characters can be stored as a string of140 bytes (octets).

The Service Center Address is described in ETSI GSM 04.11.

The Transport Protocol Data Unit is described in ETS GSM03.40.

This is a string of GSM characters, which must be translatedback into ASCII. The process is the reverse of the codingprocess described previously. This converts the charactersback from a series of octets to a series of 7 bit ASCIInumbers.

Looking at the first 6 octets:

This decoding process continues for the entire user datastring. Translating the entire string comes up with ROHDE& SCHWARZ THE QUICK BROWN FOX JUMPEDOVER THE LAZY DOG.

4.6.5 Sending and Receiving Binary Data Via SMS

Your specific application may require binary data to be sent,instead of an ASCII text message. In this case, you cansimply insert your raw data as the user data, instead of usingthe GSM character coding process. This limits you to 140octets of data. So long as your application controls theencoding and decoding of the SMS PDUs at either end of thesolution, you can use the 140 octets of user data as you seefit.

4.6.8 Establishing GPRS PDP Context

When using the GPRS Network for HTTP/FTP browsing,you must be attached to the GPRS Network before activatingPDP context.

Connection may be performed in one of the following twoways:� Automatically after powering up your MS. The GPRS

logo is displayed on your screen.

� Using the AT+CGATT=1 command. You can check yourconnection status by using the AT+CGATT? commandAT+CGDCONT=1,"IP","RTY","123.32.45.9

Following are the three main ways in which to activate PDPcontext:1. If the GPRS Wizard application is used, double-click

the button predefined as the dialer for this provider toautomatically establish PDP context. If the g18 was notpreviously attached to GPRS, it will be attached auto-matically.

Setup Configuration

1. Enter into the wizard parameters provided by youroperator.

2. Set definitions to allow your http\ftp browser to usethe g18 as a port to the Internet.

Usage

1. Open the GPRS wizard.

2. Double-click the dialer icon to select and activate theprovider of your choice (multiple providers may bedisplayed in the list).

3. After dialing, your temporary IP address and then theGPRS DATA session message will be displayed onthe handset.

4. Minimize the GPRS wizard window and use yourhttp\ftp browser (Internet Explorer, Netscape).

2. If you use AT commands to activate PDP context, youmust perform the following steps:

1. Define the PDP contact (profile). For example: AT+CGDCONT=1,"IP","RTY","

2. Define Quality of Service. For example: At+CGQREQ=3,2,4,5,8,12

3. Define minimum acceptable Quality of Service. For example: At+CGQMIN=1,0,0,0,0

4. Activate PDP context using the AT+CGACT=1command.

3. Using the ATD* command set: The GSM 07.07 version7.5.0, Chapter 10.2.1.1 states:

Request GPRS service 'D':

D*<GPRS_SC>[*[called_address>][*[L2P][*<cid>]]]]#

The g18 supports TCP/IP protocol only, and thiscommand can be used in the following format:

ATD*99***(CID)#

The CID includes the APN (defined by theAT+CGDCONT command) to which you want to beconnected. (This depends on the ability of the SIM cardto be attached to the different networks)

The format ATD*99# may also be used. In this case, theg18 will first try to activate a non-empty (predefined)CID. If the attempt fails, the g18 will try the next CID,and so on.

4.6.9 Changing the PIN Code Number

1 Check your CPIN status. If AT+CPIN? returns +CPIN:READY then proceed to the next step.If AT+CPIN? returns +CPIN: SIM PIN, enter the PINnumber and recheck whether the status is READY.

2 Check that AT+CLCK=SC,2 returns +CLCK: 1,7. Ifnot, send AT+CLCK=SC,1, your PIN# command.

3 You can now change the PIN number by using the+CPIN command as follows:AT+CPIN=Old PIN#, New PIN#

4.6.10 Writing into the Fix Dialing (FD) Phone Book

Send AT+CLCK="FD",2 (Query Status)

If the response is: +CLCK: 1,7- Enter AT+CLCK="FD",0,"PIN2".

After receiving OK, write operations are allowed in the FDarea.

If the response is: +CLCK: 0,7enter AT+CLCK="FD",1,"PIN2", OK, then enter AT+CLCK="FD",0,"PIN2".

Note

Bear in mind that the AT command AT+CGACTis not supported in all countries with GPRS. AGPRS connection is also possible withATD*99#. See the following section for moreinformation.

Note

The above list is only for the AT command level.PPP information (DNSs) is not shown here.

Note

When buffering the DTE message data in theg18 (both inbound and outbound data), thefollowing apply:

•Turning off the g18 clears any buffered data.

•Removing power from the g18 clears anybuffered data.

•Whenever the DTE drops the PPP connectionwith the g18, via LCP terminate, the buffereddata is cleared.

•Whenever the g18 drops the PPP connectionwith the DTE, with LCP terminate, the buffereddata is cleared. LCP termination triggers thetermination of the data in the g18 buffer.

•Whenever the g18 drops the PPP connectionwith the DTE, without an LCP terminate, thebuffered data is cleared. Dropping the DTRalso clears the buffer.

•When the network sends a deactivationmessage or a detached message, the g18buffer is cleared.

•When the g18 transfers data in the uplink andGPRS coverage is lost, the data may flow-off.If the mobile has lost coverage and is unable tosend the packets from the DTE to the network,the buffers will continue to store the packetsuntil the buffers are full. The DTE will then beflowed off and the packets will be stored untilthey can be sent to the GPRS network.

•The amount of time that takes before the useris notified is specified in the T3312 timer that islocated in the mobile side. The default delaytime of T3312 is 54 minutes, as per the GSM0408 specification. After 54 minutes, the g18deactivates the PDP session.

Command Function

S95 Bitmap register for extended result code.

S96 Echo cancelling feature for audio devices by ATS96=1.

S97 Antenna diagnostic feature: ATS97? responds with 000 or 001. 000 means that either the antenna is not connected or the hardware does not support this feature.

S98 ATS98=1 allows the handset’s backlight to behave as if the unit was not powered by using the TS line. It will turn off the backlight immediately, for the first time after powering up.Note: ATS98=x is allowed only for x=1.

S99 ATS99=x to define the length in ms of the hardware pulse given when the GPRS coverage is changed from no coverage to coverage. The pulse length is 2x when the data indication is sent. The default value is 30 ms; 0 value is not allowed.

S99 responds with an error if the value is greater than 2,147,483,647 or equal to zero.

S100 ATS100=x, where x defines the number of seconds. To avoid frequent hardware interrupts, the g18 uses hardware indication for data only after x seconds from the last sent character to the DTE. The default value of x is 1 second; 0 value is not allowed.

S100 responds with an error if the value is greater than 32,767 or equal to zero.

S101 Sets the wakeup line forever when x=1, and resets it when x=0. ATS101? returns the current state. These operations are allowed only when the factory bit is set. When the parameters are wrong, or the factory bit is not set, it returns an error.

4.12 ETSI 07.05 STANDARD (SMS)

The following tables list the complete set of commands asdescribed in ETSI standard 07.05. For each command it isrecommended that you use the ? option to query the modemfor the particular details of each command. For example, useAT+CR? to get the full details on the +CR command.

Block mode is a stand-alone mode that makes use of full textcommands and responses to send and receive SMSmessages. This is an older mode that is provided for compat-ibility reasons. It is recommended that PDU mode be usedinstead of block mode. Text mode is not supported by themodem. PDU mode is the preferred method since it is thesimplest and easiest to use.

4.12.1 Block Mode

SMS block mode is described fully in GSM 07.05, section 2.

S100 ATS100=x, where x defines the number of seconds. To avoid frequent hardware interrupts, the g18 uses hardware indication for data only after x seconds from the time the last character was sent to the DTE. The default value of x is 1 second; 0 value is not allowed.S100 responds with an error if the value is greater than 32,767.

S101 Sets wakeup line forever when x=1, and resets it when x=0. ATS101? returns the current state. These operations are allowed only when the factory bit is set. When the parameters are incorrect, or the factory bit is not set, returns an error.

AT Commands

You can check your connection status by using the AT+CGATT? command:

AT+CGDCONT=1, “IP”,“RTY”,“123.32.45.9”

Following are the three main ways in which to activate PDP context:

1. If the GPRS Wizard application is used, double-click the button predefined as the dialer for this provider to automaticallyestablish PDP context. If the g18 was not previously attached to GPRS, it will be attached automatically.

Setup Configuration

1. Enter into the wizard parameters provided by your operator.

2. Set definitions to allow your http\ftp browser to use the g18 as a port to the Internet.

Usage

1. Open the GPRS wizard.

2. Double-click the dialer icon to select and activate the provider of your choice (multiple providers may be displayed inthe list).

3. After dialing, your temporary IP address and then the GPRS DATA session message will be displayed on the handset.

4. Minimize the GPRS wizard window and use your http\ftp browser (Internet Explorer, Netscape).

2. If you use AT commands to activate PDP context, you must perform the following steps:

1. Define the PDP contact (profile). For example: AT+CGDCONT=1,“IP”,“RTY”,“

2. Define Quality of Service. For example: At+CGQREQ=3,2,4,5,8,12

3. Define minimum acceptable Quality of Service. For example: At+CGQMIN=1,0,0,0,0

4. Activate PDP context using the AT+CGACT=1 command.

Setup Configuration

AT+CGQMIN=1,0,0,0,0,0

AT+CGQREQ=1,0,0,0,0,0

AT+CGCONT=1,“IP”,“APN”,“0.0.0.0”,0,0 // APN – replace it with the provider name

AT

AT &F0 &D2 &C1 E0

AT V1 W1 S95=47

AT&K3

ATD*99#

3. Using the ATD* command set:

To select the provider, protocol and the profile, use ATD*99***(CID)#. In fact, providers use the ATD*99# command toattach to their GPRS service.

Note

Bear in mind that the AT command AT+CGACT is not supported in all countries with GPRS. A GPRS connectionis also possible with ATD*99#. See the following section for more information.

In the next statement, try to write a record to the SM area in the MT phone book (record 110 is in this area), with 21 digits forthe phone number, and 15 digits for text. This is valid for the MT phone book, and therefore no error is expected. However,since it is written to the SM area, the phone number is truncated to 20 digits, and the text is truncated to 14 digits.

at+cpbw=110,“123456789012345678901”,,“123456789012345” // No error when writing to MT, to a slot defined in the SMphone book

Note

When creating a new entry without a name, the response is OK, but no action takes place.

The telephone book "MT" is a combination of "ME" and "SM". Entries should be written to a specific phone book(ME or SM) instead of to the MT phone book. When writing to the SM or ME phone book, the g18 validates the stringlength for phone number and label, as defined for the specific phone book. When writing to the MT phone book, theg18 is unable to detect errors with a string length less than that allowed in MT phone book, but more than what isdefined in the specific phone book. In this case, the write action is not rejected, but the number and text will be trun-cated to the limit allowed for the specific phone book.

Note

While conducting a g18 data call, the arrival of an SMS resets the +CNMI setting, thereby notifying that somethingunexpected has occurred.

After automatically transferring a SMS/CBM message to the DTE (mt=2 and/or bm=2), the g18 waits for a +CNMAresponse from the DTE (within one minute). If DTE does not respond within this time, or if another message arrivesfrom the network, the g18 saves the message in SIM, exits from SMS mode, and sets all CNMI parameters to zero.

118 98-08901C39-A

AT Commands

In the following scenario:

1 AT CNMI=0,1,0,1,0 or CNMI=0,2,0,1,0

2 MO DATA call, connected state.

3 SM received.

The g18 will end SMS mode and reset the CNMI parameters.This will indicate to the user that something occurred during thedata call.

SMS attributes can be one of the following: received-unread, received-read, stored-sent, and stored-unsent. Sincethere are new AT commands: MMGR & MMGL that return the message without changing its attribute from received-unread to received-read, this set command can be used to change the specific message attribute from received-unread to received-read and vice versa.

The test command returns the entire available <index>es and <attribute>s supported by this command.
