  • Page 17: Product Features

    The SIM Application Toolkit supports the specific mechanism(s) required by SIM applications to interact and operate with the g20. The SIM can inform the terminal via the g20 that it has something to transmit, such as text or data. The terminal can request information from the SIM, such as local news or weather, depending on the network.
  • Page 18 Proactive SIM Proactive SIM service provides a mechanism for the SIM to initiate actions to be taken by the g20. The SIM can inform the g20 that it has information to transmit to it. The SIM can issue a variety of commands through this mechanism, including the following: •...

  • Page 19: Tcp/Ip

    RS232 to "binary mode" and back to "command mode". • Ability to use UDP and TCP simultaneously. • No need for protocol support from the terminal - only data sending and receiving. • Reduced memory utilization. g20 manages the protocol stack and therefore saves terminal memory. 98-08901C68-O...

  • Page 20: Audio

    • The g20 can transfer data with the WEB using either TCP/IP or UDP/IP protocols. • The protocol stacks in the terminal or in the OEM must be managed when using TCP/IP or UDP/IP protocols. The g20 software can manage these stacks internally. This enables the g20 to relieve the terminal from the job of managing these protocols.

  • Page 21: Figure 3. Sidetone

    Product Features 2.1.3.2 Features and Benefits The following algorithm related features are provided: 2.1.3.2.1 Sidetone Sidetone reduces the microphone audio input that is routed to the selected speaker so that the person speaking can hear himself or herself talking. This creates a slight echo because the speaker sound then gets picked up again by the microphone and is again routed to the speaker, and so on.

  • Page 22: Java Api

    Overview Java API provides a new dimension to the g20 integration. In the regular standard configuration the g20 is connected to a terminal via RS232 and controls it using a set of AT commands. Java API enables the user to write and execute Java written programs directly on the g20's CPU.

  • Page 23: Gprs Operation

    Technical Description (GPRS - Class B Operation) The g20 is attached to both GPRS and other GSM services, but can only operate one set of services at a time (GPRS or CSD). The g20 can activate a GPRS context and at the same time be alerted for an incoming CSD call.

  • Page 24: Csd Operation

    GSM network operators typically support the non-transparent CSD bearer service through a modem interworking function. This means that a g20 initiates a data call and the network routes the call to the modem interworking function, which is located at the Mobile Switching Centre (MSC) of the GSM network.

  • Page 25: E-Otd

    Technical Description All measurements are made using hardware that already exists in the g20. There is no need for the terminal software to implement anything. Mechanisms located in both the network and the g20 run measurements and calculation of the location.

  • Page 26: Features And Benefits

    The following actions are enabled during a data session: • Incoming call alert string RING (while g20 is in GPRS session) • Answering to incoming call via the ATA command (while g20 is in GPRS session) • Receive Incoming SMS indication •...

  • Page 27: Technical Description

    Note SENDING SMS 2.6.1 Overview The SMS feature provides the means for transferring messages between the g20 and the terminal, and the reporting of SMS reception events. g20 SMS implementation is based on the GSM 07.05 specification. 2.6.2 Features and Benefits The SMS, as defined within the GSM 900 / 1800 / 1900 digital mobile phone standard, has several unique features: •...

  • Page 28: Technical Description

    2.6.3 Technical Description The g20 memory can contain up to 30 incoming messages. A new incoming message is saved in the first free memory location, from index 1 up to index 30. The g20 memory can contain up to 73 outgoing messages. A new outgoing message is saved in the next free memory location, from index 101 up to index 352.

  • Page 29: Character Sets

    GSM is the default alphabet, as described in section 8.7 (GSM character table) . g20 can store messages coded in any alphabet on the SIM, irrespective of support of an individual alphabet. The default alphabet is based on 7bit characters.

  • Page 30: Character Set Management

    • Latin 5 (Turkish) • Latin 6 (Nordic) g20 supports Latin 1. Latin 1 covers most West European languages, such as French (fr), Spanish (es), Catalan (ca), Basque (eu), Portuguese (pt), Italian (it), Albanian (sq), Rhaeto-Romanic (rm), Dutch (nl), German (de), Danish (da), Swedish (sv), Norwegian (no), Finnish (fi), Faroese (fo), Icelandic (is), Irish (ga), Scottish (gd) and English (en).

  • Page 43: Introduction To At Commands

    The basic system configuration contains a modem and a terminal. The g20 is the modem and may be referred to as the DCE, the phone, the mobile or the radio. The terminal may be referred to as the DTE or the TE...

  • Page 44: At Commands Protocol

    Thus a request is called a "command". Each command must be answered by a "results code" from the g20. The results code reports the command status to the terminal. Some commands may include several "Response" requests (between 0 to K) to send data back to the terminal.

  • Page 45: Results Code Structure

    Results Code Structure When a command is issued, the g20 responds with a message, called a "Result Code", which tells the terminal the result of the command that was requested. Result codes can indicate, for example, the execution status of the command or the remote modem connection status.

  • Page 46: Response And Indications Structure

    The AT commands message flow and structure may be configured by the terminal. The g20 can be configured not to follow a command with an echo and/or results code. It can be configured to transmit the results code in either of two ways: Verbose or Numeric. This (and other) configurations can be set using the following commands: Command line termination character (default setting 0x13).

Example of compound_value: <value1>,<value2>,…,<valueN> 3.6.1 Numeric Constants Numeric constants are expressed in decimal, hexadecimal, or binary form. In the g20, the definition of each command specifies which form is used for values associated with that command. 3.6.2 String Constants String constants consist of a sequence of displayable ASCII characters.

  • Page 49: Parameter Read Command Syntax

    When a command is aborted, this not mean that its operation is reversed. In the case of some network commands, when the abort signal is detected by the g20, although the command is aborted following g20-network negotiation, the operation might be fully completed, partially completed or not executed at all.

  • Page 50: Core At Commands

    3.10 CORE AT COMMANDS The g20 responds to a limited commands set when the SIM card is not functioning, for any of the following reasons: • No SIM card is inserted in the g20 SIM tray. • A bad, locked or blocked SIM card inserted.

  • Page 52 Introduction to AT Commands Table 5. Core AT Commands (Continued) Command Description Page This command selects the line modulation standard. This command is used for backward compatibility only. This command hangs-up, or terminates a particular call, whether is a voice or data call, or whether it is an incoming, originating, waiting or connected call.

  • Page 53: At Commands Reference

    In the g20 development, special care and thought was given to g18 backward compatibility. In order to enable the simple replacement of the g18 with the g20 (without the need to change the terminal’s code) as well as to enable the same syntax, AT family compatibility groups were created.

  • Page 61: Capability Reporting

    Capability Reporting This set of commands allows an accessory to determine the level of protocol and other support that is provided by the g20. This includes capturing information about the protocol version that is implemented (to detect older g20s that may not support all commands), as well as determining which optional commands are implemented in a particular g20 software load.
  • Page 62 +MAPV, Get Accessory Protocol Version This command returns the version of the accessory protocol that is supported in the g20. This version consists of a major version number and a minor version number, and should correspond with the protocol version number reported by the first g20 release including that command.

This command returns a percentage number representing the current amount of memory that is used in the shared memory storage for the phone book and date book.

  • Page 64: Call Control

    The g20 working modes can be divided into two modes of operation. • Data Mode: In this mode, once the g20 has established a link with the remote modem, it does not respond to any data passing through it (except for the Escape Sequence search). The g20 becomes a transparent link, connecting the terminal with the remote side.

  • Page 65: Receiving A Data Call

    When using computers in the "Dumb Terminal mode", return to the Command mode by typing the Escape Sequence, +++, and then hang up by typing the Hang up command as follows: ATH <Enter> If the g20 responds with "OK", the dial connection is closed. 4.3.1.4 Dialing to an Electronic Telephone Service When you dial to an electronic telephone service such as telephone banking, you must typically instruct the modem to dial a number, then to wait for call establishment, and then send the password for entering the banking account.

  • Page 66: Call Control At Commands

    For more information about call failure, use the AT+CEER command, described in “+CEER, Extended Error Report” on page 200. If there is an active voice call and the terminal sends another ATD voice call command to the g20, the active call is put on hold and the new number is called.

  • Page 204: Sleep Mode Commands

    The g20 will not enter sleep mode unless the terminal enables the g20 sleep mode and signals its readiness for sleep. For this purpose, a set of AT commands and dedicated HW lines are defined.

  • Page 205: Figure 12. Wakeup-In Line

    The terminal uses the Wakeup-In line (pin #16) to wake up the g20 when it wants to send data. When the Wakeup-In line is low, the g20 will not enter the Sleep mode. If the terminal has data to send while the g20 is sleeping, it activates the line (brings it to active low), then waits 30 ms (the time required to wake the g20).

  • Page 206: Figure 13. Wakeup-Out Line

    The g20 follows these steps in order to wake up the terminal: • The g20 indicates to the terminal that it has data and that it must wake up. The g20 uses the Wakeup-Out Line (pin #26) (brings it to active low).

  • Page 207: Figure 15. G20 Lines When S24 > 0

This command is used for backward compatibility only. &C This command determines how the state of the DCD line relates to the detection of the received line signal from the distant end.
  • Page 320 +CCFC This command enables control of the call-forwarding supplementary service. +CCLK This command reads/sets the g20's current date and time settings. +CCWA This command controls the Call Waiting supplementary service, including settings and querying of the network by the g20.
  • Page 321 This command enables the emulated pressing of keys, or virtual keycodes, as if entered from the g20 keypad or from a remote handset. +CLCC This command returns a list of all current g20 calls and their statuses, and also enables/disables the unsolicited indication of the call list. +CLCK This command locks, unlocks or interrogates a g20 or a network facility <fac>.
  • Page 322 This command enables the unsolicited notification of the accessory when a new SMS message is received by the g20. +CNUM This command returns up to five strings of text information that identify the g20. +COLP This command refers to the GSM supplementary service COLP, Connected Line Identification Presentation, which enables a calling subscriber to get the connected line identity (COL) of the called party after setting up a mobile originated call.
  • Page 323 This command handles the selection of the SCA (Service Center Address) and the TOSCA (Type of SCA). +CSCS This command selects the TE character set used on the g20. +CSDH This command controls whether detailed header information is shown in the text mode result code.
  • Page 324 This command controls the various algorithm features, such as sidetone, echo cancel and noise suppress. +MAID This command returns the AT Feature Review that is supported in the g20. +MAMUT This command controls the muting/unmuting of all input paths (MIC, HDST_MIC, DIGITAL_RX).
  • Page 325 This command enables an intelligent car kit to indicate the ignition state of the vehicle to the g20, which enables the g20 to turn on and off with the ignition, or to enter a power saving state when the ignition is turned off.
  • Page 326 +MSCTS This command defines the behavior of the CTS line when the g20 is in Sleep mode. +MTCTS This command sets the CTS pin of the RS232 to not active (high), waits one second and then returns the CTS to active (low).
  • Page 327 This command places a voice call to the last number dialed. This command defines whether the g20 echoes the characters received from the accessory, (whether input characters are echoed to output). This command selects the line modulation standard. This command is used for backward compatibility only.
  • Page 328 This command sets the value of the delay before sending the data to the terminal. This S-parameter activates/disables the Sleep mode. If the parameter value is greater than 0, it represent the number of seconds till the g20 enters sleep mode. This S-parameter represents the decimal IA5 (International Alphabet No. 5) value of the command line termination character that terminates an incoming command line.
