LCD Alarm or Warning

Meaning / Possible Cause

Message

 

 

 

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 Time-

 

out;

 

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 unsupported format. Contact

(N=field number;

TOC to confirm that the version of application code in your IRD is current.

M=line number)

 

 

 

Bad Video Data

Video PES stream appears to be invalid. Check if other IRDs see similar

 

problem on the same program.

 

 

Bad Video PTS

Excessive jumps or jitter in video PTS values. There may be a defective uplink

 

encoder or mux.

 

 

Content for ASI N/A

Program content requested to route to ASI output cannot be found in over-

 

satellite transport mux. Contact network TOC and advise.

 

 

Content Routing

ASI transport output bears no program content because a Content Routing

Problem

Table has not been loaded from the network or is corrupt. Contact network

 

TOC.

 

 

Eb/N0 Margin Warning

Eb/N0 value less than sum of Threshold + Margin—evaluated over 10 sec.

 

intervals. Unless the margin setting is incorrect, this indicates a marginal

 

downlink.

 

 

FP Email Fail

An FP Email message was received which was corrupt or invalid. User should

 

acknowledge the warning to clear, and then notify the network TOC.

 

 

High Error Rate

High errored seconds rate, presumably useless signal—evaluated over 60 sec.

 

intervals. Signal-to-noise ratio is insufficient or there is severe terrestrial or

 

antenna cross-pol interference.

 

 

High RF Level

There is carrier lock, but the RF signal level is too high.

 

 

ID Tag Mismatch

Carrier ID frequency text mismatch. User or network has entered carrier

 

frequency text or tag site ID incorrectly or unit is on the wrong carrier.

 

 

ID Tags Lost

Carrier ID tags disappeared. There may be a failure at the uplink inserter

 

(UMX5010) or loss of COMPEL® PID. See "ID Tag Mismatch" indication.
