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.

Message Meaning / Possible Cause
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
(N=audio port number)
Requested audio PES stream for port N is invalid or cannot be decompressed
or processed. There may be a problem in the hardware for that audio port or in
the uplink Encoder.
Aud N Buff Overflow
(N=audio port number)
Audio port N PES data buffer overflow. Audio PES data being 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
(N=audio port number)
Audio port N PES data not available (buffer underflow). here 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
(N=audio port number)
No audio PID found in PMT with assigned language 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
(N=audio port number)
Audio PID found in PMT with requested language descriptor but no PES data
detected. Check uplink encoder.
Aud N Type Invalid
