UNITY 4600 USER’S MANUAL

4.3 Alarms and Warnings

The alarm and warning system is intended to alert the local user of a present or impending loss of services. Table 4.1 below lists many (but not all) of the possible alarm and warning messages that the U4600 may display. For problems you cannot resolve on your own, please contact Wegener Customer Service (see Chapter 5), and be prepared to describe your signal setup, U4600 configuration, and any displayed alarm and warning messages.

Alarms

An alarm is asserted when the unit is unable (or presumed to be unable) to perform a required function or deliver required services.

Warnings

A warning is asserted when an alarm condition is imminent or to indicate other condi- tions requiring user attention.

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 bad PES data	Requested audio PES stream for port N is invalid or cannot be decompressed
(N=audio port number)	or processed. There may be a problem in the hardware for that audio port or in
	the uplink Encoder.
Aud N Buff Overflow	Audio port N PES data buffer overflow. Audio PES data being delivered faster
(N=audio port number)	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 may be a problem
(N=audio port number)	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 descriptor for hard-
(N=audio port number)	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 no PES data
(N=audio port number)	detected. Check uplink encoder.
Aud N Type Invalid	Audio PES stream type not supported.
(N=audio port number)
