3.3.4 Type1CID

Call(s):

void Type1CID(cid_sData *pData, teldef_tsControl *pControl, teldef_tsSample

*pSample);

Required Headers: teldefs.h, cid1.h

Arguments:

Table 3-4. Type1CID Arguments

Description: The Type1CID function performs on-hook FSK reception. According to the control

information from its arguments, it enables the FSK receiver and passes the FSK to the upper layer process

to display the data. This function should be called 1600 times per second.

hookSwitch = 0 (on-hook):

•

pSample.line[] samples are inputs to this function and are decoded into data bytes when caller ID

is present

•

pSample.line[] samples are outputs from this function and are ringer generator samples when

ringing is present; otherwise, these samples are filled with zeros

•

pSample.audio[] samples are ignored and filled with zeros

hookSwitch = 1 (off-hook):

•

If handsFreeLayer1 is set, pSample.gec[] are copied into pSample.line[] samples; otherwise,

pSample.line[] samples are unchanged

•

If a DTMF digit has been requested by setting dtmfRequest, pSample.audio[] is filled with DTMF

samples; otherwise, pSample.audio[] samples are unchanged

Returns: None

Special Issues: None

Code Example: None
