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
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
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.

•
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
