Using Parameters

• Optional parameters are enclosed in square brackets. If optional parameters are omitted, the current settings
are used until you change them.
• Optional parameters or subparameters can be omitted unless they are followed by other parameters. If you
want to omit a parameter in the middle of a string it must be replaced by a comma. See also example 1.
• A parameter value enclosed in square brackets represents the value that will be used if an optional parameter
is omitted. See also example 2.
• When the parameter is a character string, e.g.
marks, e.g. "Charlie Brown" or "+49030xxxx". Symbols in quotation marks will be recognized as strings.
• All spaces will be ignored when using strings without quotaton marks.
• It is possible to omit the leading zeros of strings which represent numbers.
• If an optional parameter of a V.250 command is omitted, its value is assumed to be 0.
