Mode: asynchronous or synchronous

„Description

The dx_mreciottdata( ) function records voice data from two TDM bus time slots. The data may be recorded to a combination of data files, memory or custom devices.

This function is used for the transaction record feature, which allows you to record two TDM bus time slots from a single channel. Voice activity on two channels can be summed and stored in a single file, device, and/or memory.

Parameter

Description

devd

specifies the valid channel device handle on which the recording is to occur.

 

The channel descriptor may be that associated with either of the two TDM bus

 

transmit time slots or a third device also connected to the TDM bus.

iotp

points to the I/O Transfer Table Structure, DX_IOTT, which specifies the

 

order of recording and the location of voice data. For more information on this

 

structure, see the DX_IOTT data structure.

tptp

points to the Termination Parameter Table Structure, DV_TPT, which

 

specifies the termination conditions for recording. For more information on

 

this structure, see the DV_TPT data structure.

xpb

points to a DX_XPB structure, which specifies the file format, data format,

 

sampling rate, and resolution for I/O data transfer. For more information on

 

this structure, see the DX_XPB data structure.

mode

specifies the attributes of the recording mode. One or more of the following

 

values can be specified:

 

• 0 – standard record mode

 

• RM_TONE – transmit a 200 msec tone before initiating record

sc_tsinfop

points to the SC_TSINFO data structure and specifies the TDM bus transmit

 

time slot values of the two time slots being recorded.

 

In the SC_TSINFO structure, sc_numts should be set to 2 for channel

 

recording and sc_tsarrayp should point to an array of two long integers,

 

specifying the two TDM bus transmit time slots from which to record.

Note: When using RM_TONE bit for tone-initiated record, each time slot must be “listening” to the transmit time slot of the recording channel; the alert tone can only be transmitted on the recording channel’s transmit time slot.

After dx_mreciottdata( ) is called, recording continues until one of the following occurs:

•dx_stopch( ) is called on the channel whose device handle is specified in the devd parameter

•the data requirements specified in the DX_IOTT structure are fulfilled

•one of the conditions for termination specified in the DV_TPT structure is satisfied

„Cautions

•All files specified in the DX_IOTT structure are of the file format specified in DC_XPB.

•All files recorded will have the same data encoding and rate as DC_XPB.
