1.7.15. Redefine Call Progress Tone Attributes (BRI Only)

The GCIS_EXID_TONEREDEFINE extension ID redefines a call progress tone's attributes in the tone template table. The tone template table resides in the firmware and is used during call establishment. The template contains common call progress tone types and is preset to default values at initialization (see Tone Template Table in isdnapi.doc). The current template has a total of eight entries, of which only four are defined. The other four are reserved for future use.

The gc_Extension(GCIS_EXID_TONEREDEFINE) function allows you to redefine the existing tone template, but not the functional meanings of the call progress tones.

The following table provides the parameter inputs for the gc_Extension( ) function.

Parameter	Input
target_type	GCTGT_GCLIB_CHAN
target_id	line device handle of the device
ext_id	GCIS_EXID_TONEREDEFINE
parmblkp	set_id - GCIS_SET_CALLPROGRESS
	parm_id - GCIS_PARM_CALLPROGRESSTONE_TYPE
	values - 0x01: Dialtone 0x02: Busytone 0x03: Reorder 0x04: Ringback
	value_type - unsigned char
	set_id - GCIS_SET_TONE
	parm_id - GCIS_PARM_TONE_DURATION
	values - range is 1 to 65535. Set to -1 to play forever
	value_type - unsigned short
	parm_id - GCIS_PARM_TONE_FREQ1 -
	values - range is 200 to 3100 Hz.
	value_type - unsigned short
	parm_id - GCIS_PARM_TONE_AMP1
	values - range is -40 to +3 dB
	value_type - short
	parm_id - GCIS_PARM_TONE_FREQ2-
	values - range is 200 to 3100 Hz
	value_type - unsigned short
	parm_id - GCIS_PARM_TONE_AMP2
	values - range is -40 - +3 dB.
	value_type - short
	parm_id - GCIS_PARM_TONE_ON1
	values - 1 to 65535 ms. Set to 1 or greater for continuous tone.
	value_type - unsigned short
	parm_id - GCIS_PARM_TONE_OFF1
	values - range is 0 to 65534 ms. Set to 0 to play a continuous tone.
	value_type - unsigned short
mode	EV_SYNC or EV_ASYNC

Termination Events

• GCIS_EXEV_TONEREDEFINE - indicates that the tone was successfully redefined
• CCEV_EXEV_TONEREDEFINEFAIL - indicates that the function failed.

Note: This function is not supported for the BRI/2 board or for PRI protocols.
