ISU AT Command Reference Introduction CI Cell Identifier CTS (V.24 Signal) Clear To Send. This signal is normally used in controlling the flow of data to the ISU. (See RTS) DCD (V.24 Signal) Data Carrier Detect. This is a signal from the ISU that indicates that it is connected to the far-end modem for data transfer. DCE Data Communications Equipment, i.e., a data adaptor or modem. In this product, DCE refers to the ISU. DSR (V.24 Signal) Data Set Ready.

ISU AT Command Reference Modem Overview 2 Modem Overview 2.1 DTE-ISU Interchange Circuits The communication between the ISU (Iridium Subscriber Unit) and the DTE (Data Terminal Equipment) follows the ITU-T V.24 (RS-232) recommendation. Please see reference [4] for details. 2.2 9-Wire and 3-Wire Operation The ISU supports a full 9-wire interface to the DTE, incorporating hardware handshaking and flow control.
PAGE 16
ISU AT Command Reference Modem Overview (ATOn) is used to return to the data mode. These mode transitions are made without terminating the call. 2.5 Hardware Failure Reporting If the ISU detects a hardware problem during initialisation, the ISU may be unable to function correctly.
PAGE 17
ISU AT Command Reference Command Overview 3 Command Overview 3.1 Command Types The ISU employs two principle types of AT commands: basic and extended. The two types have differing syntax used to query and adjust their settings. They also have unique reference standards. A specific basic AT command is used to reference S-registers and query and adjust their settings. Its syntax is similar to that of extended AT commands. 3.
PAGE 18
ISU AT Command Reference Command Overview Extended Cellular Commands  +C prefix  Used for GSM cellular phone-like functions  Standards: ETSI specifications GSM 07.07 (reference [2]) and GSM 07.05 (reference [3]) Extended Data Compression Commands  +D prefix  Used for data compression  Standard: V.25ter (reference [1]) Extended Generic Commands  +G prefix  Used for generic DCE issues such as identities and capabilities  Standard: V.
PAGE 19
ISU AT Command Reference 3.5 Command Overview Command Entry An AT command is a string of characters sent by the DTE to the ISU while the ISU is in command mode. A command string has a prefix, a body, and a terminator. The prefix consists of the ASCII characters AT or at. The body is a string of commands restricted to printable ASCII characters. The default terminator is the character.

(no separators) 3.6 Command Responses A result code is sent to the DTE in response to the execution of a command. It may also occur unsolicited from other conditions such as an incoming call (e.g., RING). Responses returned as a result of a query are called information responses.
