Chapter 1 – Introduction Chapter 1 – Introduction Scope of This Document This document describes the AT-command based messages exchanged between an application and the Multi-Tech Systems, Inc. products in order to manage GSM-related events or services. Related Documents This interface specification is based on the following recommendations: [1] ETSI GSM 07.
Chapter 2 – AT Command Features Chapter 2 – AT Command Features Line Settings A serial link handler is set with the following default values (factory settings): • Autobaud • 8 bits data • 1 stop bit • no parity • RTS/CTS flow control Please use the +IPR, +IFC and +ICF commands to change these settings. Command Line Commands always start with AT (which means ATtention) and finish with a character.
Chapter 3 – General Behaviors Chapter 3 – General Behaviors SIM Card Insertion and Removal Procedures SIM card Insertion and Removal procedures are supported. Software functions rely on positive reading of the hardware SIM detect pin. This pin state (open/closed) is permanently monitored. When the SIM detect pin indicates that a card is present in the SIM connector, the product tries to set up a logical SIM session.
Chapter 3 – General Behaviors Since the maximum length for the numbers in the ADN, FDN, and LND phonebooks is 60 digits: • if the user tries to dial a number that exceeds 60 digits: +CME: 3 Before the user can perform a call, the number of free records in the EFEXT1 is checked for availability of free space to store this number. • If there are free records left, the call is setup. • Otherwise, +CME: 20 error is returned (Memory Full). See Recommendation 3GPP 11.11 for more details.

Appendix E – Coding of Alpha Fields in the SIM for UCS2 Appendix E – Coding of Alpha fields in the SIM for UCS2 The coding can take one of the three following structures. If the ME supports UCS2 coding of alpha fields in the SIM, the ME shall support all three coding schemes for character sets containing 128 characters or less; for character sets containing more than 128 characters, the ME shall at least support the first coding scheme.
Appendix E – Coding of Alpha Fields in the SIM for UCS2 Example 3 Byte 1 '82' Byte 2 '05' Byte 3 '05' Byte 4 '30' Byte 5 '2D' Byte 6 '82' Byte 7 'D3' Byte 8 '2D' Byte 9 '31' In the above example • Byte 2 indicates there are 5 characters in the string • Bytes 3 and 4 contain a sixteen bit base pointer number of '0530', pointing to the first character of the Armenian character set. • Byte 5 contains a GSM Default Alphabet character of '2D', which is a dash "-".
Appendix F – Command Execution and Dependence on SIM Appendix F – Command Execution and Dependence on SIM The following table lists AT command execution syntax and the execution condition. The SIM dependency column indicates if the command behavior will vary if another card is used. For example, it will vary for phonebook reading commands. The Intermediate column indicates if intermediate response can occur.
