This MMC provides various MGI DSP options.

No	Parameter	Description	Default
00	CODEC-FRAME	Selects which audio CODEC compression will be used	G.729A –
		and the transmission interval time of VoIP packets gen-	20 Ms
		erated by the MGI card. MGI3 card supports
		G.729A(8 K), G.729(8 K), G.711(64 K), and
		G.723.1(5.3~6.4K).
01	ECHO CANCEL	Enables or disables echo cancellation. This function	ENABLE
		removes the echo that is generated by voice reflection
		and packet delay.
02	SILENCE SUP	This parameter determines whether silence suppression	DISABLE
		is used. This prevents transmission during the silence
