Message
(N=field number;
M=line number)
Low RF level
No ASI stream
No audio for Port N
No Carrier Lock
No COMPEL
No COMPEL PID
No Def for mapping
Meaning / Possible Cause
VBI data for field N, line M has disappeared. If any is
expected, contact network TOC.
There is carrier lock, but the RF signal level is too low.
The version number on the Program Allocation table has
changed and a new program lineup has been submitted.
Changes have been made on uplink transport mux.
The version number on one or more of the Program Map
Tables has changed with a new PID lineup submitted.
Changes have been made on uplink transport mux.
Corrupt or missing input ASI stream. Only applicable if ASI
input is available and selected. Check connection and
source.
No "free" otherwise-unassigned audio can be allocated to wild-
card-assigned port N. There may be fewer audio PES streams
than installed audio ports. If so, explicitly assign a desired lan-
guage descriptor to this audio port.
Carrier lock cannot (or has not) been acquired and main-
tained. Check that requested settings are correct. Check RF
level indication and RF connection. For new installations,
check antenna pointing and polarization.
Data traffic is detected at designated packet ID (PID) for
COMPEL . However, no valid COMPEL messages have
been detected during the last two minutes. There may be no
connection to the network. If required to maintain a connec-
tion, the unit will eventually attempt an automatic recovery
to a backup preset. To debug, check that the COMPEL sys-
tem at the uplink is functional and that the data connection
to inserter (such as UMX5010) is good. Also check for fault
indications or functional problems at UMX5010.
No traffic detected at designated packet ID (PID) for COM-
PEL, so no connection is made to the network. The COM-
PEL PID setting in the unit may be incorrect. Also see "No
COMPEL indication".
ASI transport output bears no program content because an
Output Definition Table has not been loaded from the net-
work. Contact network TOC.
IRD is required to get IP settings from DHCP server but
none are detected on the LAN.
