ISU AT Command Reference

ISU AT Command ReferencePhase III AT Commands7.13 +CCLK - Real-Time ClockSet Command: +CCLK=[]Sets the real-time clock of the ISU. If setting fails, ERROR is returned.: string type value; format is “yy/MM/dd,hh:mm:ss±zz”, where characters indicate year (two lastdigits), month, day, hour, minutes, seconds and time zone. There is no blank space between thetwo double quotes. Since time zone feature is not supported in Iridium, this particular field (±zz) isignored if it is entered. The range of valid years is between 1970 and 2058.For example, 15 th of May 2002, 22:10:00 hours can be set using +CCLK= “02/05/15,22:10:00”.Read Command: +CCLK?Read command returns the current setting of the clock.+CCLK: 7.14 -MSVTS - DTMF Generation in Voice CallSet Command: -MSVTS=Generate the specified DTMF tone (i.e., send tone DTMF message to network). The parameter shall consist of elements in a list where each element is separated by a comma. Each element should eitherbe (1) a single ASCII character; or (2) string that follows the format: [,] with each stringenclosed in square brackets “[]”. The string parameter values are defined as follows: specifies the string of tones to be played or generated. The valid values are (in ASCII):‘0’-’9’, ‘#’, ‘*’ specifies the duration of each tone in 180-millisecond unit. Default value is 1 for 180 ms.For example, the command string -MSVTS=1,[9,2],[5,3] will:1. Generate DTMF 1 with a duration of 180 ms (default).2. Generate DTMF 9 with a duration of 360 ms (2 * 180 ms).3. Generate DTMF 5 with a duration of 540 ms (3 * 180 ms).Test Command: -MSVTS=?List the supported parameter settings. The response is in the form:-MSVTS: (supported s),(supported s)Note: DTMF generated with the –MSVTS command is never played back locally as tones and is thereforeneither played nor muted under control of the –MSVLS command.Version 2.6March 30, 2006 54
