	Table 4.1: Alarm and Warning Descriptions
	LCD Alarm or Warning		Meaning / Possible Cause
	Message
	App Self-testing		New application software was recently promoted from the
			backup to primary executing position and is now performing
			its initial self-test. This is a Warning for normal behavior and is
			not a fault.
	App SW d-load fail		Download of application software to backup flash space has
			failed. Contact network TOC and advise.
	App SW switch fail		Unable to switch to backup software from network command,
			usually because that software image is not available or
			corrupted.
	ASI TS muted		ASI Transport output has been muted per user or network
			command.
	Aud N buff overflow		Audio port N PES data buffer overflow. Audio PES data being
	(N=audio port number)		delivered faster than can be decompressed. There may be a
			problem with the STC at uplink Mux or in the IRD.
	Aud N data lost		Audio port N PES data not available (buffer underflow). here
	(N=audio port number)		may be a problem in the hardware for that audio port or in the
			uplink encoder. Check that PTS values in the audio stream do
			not grossly lead PCR.
	Aud N LD not in PMT		No audio PID found in PMT with assigned language
	(N=audio port number)		descriptor for hard-assigned port N. Check that the language
			descriptor requested by the user or network is actually
			assigned to an existing audio stream.
	Aud N PID not found		Audio PID found in PMT with requested language descriptor but
	(N=audio port number)		no PES data detected. Check uplink encoder.
	Aud N type invalid		Audio PES stream type not supported.
	(N=audio port number)
	Auto-Recovery		Auto-recovery in progress. This may be caused by any of the
			following problems on a previously commanded or
			successfully acquired transport stream: (1) IRD unable to
			deliver services for time exceeding Services Recovery
			Timeout; (2) IRD required to maintain connection to
			COMPEL→ and IRD has not detected COMPEL for time
			exceeding Network Recovery Timeout; or (3) IRD detects
			invalid incoming COMPEL header.
	Bad audio N PTS		Excessive jumps or jitter in Audio port N PTS values
	(N=audio port number)
	Bad PMT		One or more Program Map Tables are corrupted. See "No
			PMT" indication.
	Bad Sec Micro SN		Serial number read from secure processor does not match
			unit. There may be a an attempt at piracy, a defective NVRAM
			memory, or a defective secure processor.
	Bad VBI Data FN LM		VBI data for field N, line M is unrecognized or in an
	(N=field number;		unsupported format. Contact TOC to confirm that the version
	M=line number)		of application code in your IRD is current.
