dx_getxmitslot( ) — get TDM bus time slot number of voice transmit channel
dx_getxmitslot( )
get TDM bus time slot number of voice transmit channel
!
!!
! Description
The dx_getxmitslot( ) function returns the time division multiplexing (TDM) bus time slot number
of the voice transmit channel. The TDM bus time slot information is contained in an SC_TSINFO
structure that includes the number of the TDM bus time slot connected to the voice transmit
channel. For more information on this structure, see SC_TSINFO, on page 529.
Note: TDM bus convenience function nr_scroute( ) includes dx_getxmitslot( ) functionality.
A voice channel on a TDM bus-based board can transmit on only one TDM bus time slot.

! Cautions
• This function fails when an invalid channel device handle is specified.
• On DM3 boards, this function is supported in a flexible routing configuration but not a fixed
routing configuration. This document assumes that a flexible routing configuration is the
configuration of choice. For more information on API restrictions in a fixed routing
configuration, see the Voice API Programming Guide.
