r2_creatfsig( ) — create R2/MF forward signal tone
r2_creatfsig( )
create R2/MF forward signal tone
!

! 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 dx_blddt( ) 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.
Name: int r2_creatfsig(chdev, forwardsig)
Inputs: int chdev
• channel device handle
int forwardsig
• group I/II forward signal
Returns: 0 if success
-1 if failure
Includes: srllib.h
dxxxlib.h
Category: R2/MF Convenience
Mode: synchronous
Platform: Springware
Parameter Description
chdev specifies the valid channel device handle obtained when the channel was
opened using dx_open( )
forwardsig specifies the name of a Group I or Group II forward signal which provides the
tone ID for detection of the associated R2/MF tone (or tones). Set to
R2_ALLSIG to enable detection of all 15 tones or set to one of the following
defines:
