! Description
The r2_creatfsig( ) function is a convenience function that defines and enables leading edge
detection of an R2/MF forward signal on a channel. This function calls the
detection of an R2/MF forward signal on a channel. This function calls the
function to
create the template.
User-defined tone IDs 101 through 115 are used by this function.
Note:
R2/MF signaling is typically accomplished through the Global Call API. For more information, see
the Global Call documentation set. The R2/MF function described here is provided for backward
compatibility only and should not be used for R2/MF signaling.
