Enabling the R2 Protocol

Inbound calls require generation of call progress tones. If a call has been accepted, BSMI will generate a finite number of RING tone cycles before entering the answered state. If a call has been rejected, BSMI will generate the BUSY signal until the call is cleared by the outbound side. Table 24 identifies the IISDN_CPGEN_MF_ PARAMS structure that contains the parameters required to define a call progress signal for generation by a DSP resource.

powerTone2	Power of tone #2	0.5 dB, relative to
		power0dBm
		Output
numCadences	Number of distinct		[1,2,3]
	cadences to generate
	(on/off pairs)
makeTime1	Duration of first ON	ms	[1 - 8191]: tone plays

			>0: tone played
			continuously
breakTime1	Duration of first OFF	ms	[1 - 8191]: tone is off
	cadence		for this duration
			0: silence not

			cadences
			< 0: silence is played
			continuously
