Parameters

a structure of the following type:

typedef struct sm_channel_info_parms {
	tSMChannelId channel;					/* in */
	tSM_INT card;						/* out */
	tSM_INT ost;						/* out */
	tSM_INT ots;						/* out */
	enum kSMTimeslotType otype;				/* out */
	tSM_INT ist;						/* out */
	tSM_INT its;						/* out */

	tSM_INT group;						/* out */
	tSM_INT caps_mask;					/* out */
} SM_CHANNEL_INFO_PARMS;

Description

This call allows an application to locate a previously allocated speech processing resource so that a data can be switched through to it by means of a call to the Aculab switch driver API.

If channel is an identifier for a previously allocated input, half-duplex, or full-duplex channel, then the parameters ist, and its returned by this call may be assigned to the ost and ots parameters of a switch driver CONNECT_MODE call to sw_set_output, with <ist, its> in the OUTPUT_PARMS parameter block being set to the source of the data to be processed by the channel.

If channel is an identifier for a previously allocated output, half-duplex, or full-duplex channel, then the parameters ost, and ots returned by this call may be assigned to the ist and its parameters of a switch driver CONNECT_MODE call to sw_set_output with <ost, ots> int the OUTPUT_PARMS parameter block being set to the destination for data to be generated by the channel.

The parameter card is an obsolete parameter set to the value -1

The parameter group is an obsolete parameter set to the value zero.

The parameter caps_mask is an obsolete parameter set to the value zero.
