Cisco Systems 4028650000000 installation and operation guide DVB-S/DVB-S2 TS

Selection	Options	Description	Default
DVB-S/DVB-S2 TS	-5.0 to 20.0	This sets how the receiver reacts when the	0.0
Mute	dB	signal quality is severely degraded when
		using DVB-S or DVB-S2 modulation. This
		allows you to set the transport C/N
		margin values for the receiver. The
		receiver uses these noise values/settings
		as limits during normal operation to
		determine whether to mute the transport
		in the event of a noisy signal, poor signal
		or no signal condition.
		The mute is the lower limit for the
		transport C/N margin setting. The
		transport will be muted when the C/N
		margin is below the cutoff setting for a
		nominal delay of 1 second. The delay is
		between the time the condition is first
		detected and the time the transport is
		muted.
DVB-S/DVB-S2 TS	-5.0 to 20.0	This sets how the receiver reacts when the	0.1
Restore	dB	signal quality is severely degraded when
		using DVB-S or DVB-S2 modulation. This
		allows you to set the transport C/N
		margin values for the receiver. The
		receiver uses these noise values/settings
		as limits during normal operation to
		determine whether to mute the transport
		in the event of a noisy signal, poor signal
		or no signal condition.
		This is the upper limit for the transport C/
		N margin setting. The transport will be
		un-muted (e.g., restored) when the C/N
		margin rises above the Restore setting for
		a nominal delay of 8 seconds. The delay is
		between the time the condition is first
		detected and the time the transport is
		restored.
