Meaning / Possible Cause
Excessive jitter in Program Clock Reference values. This
may degrade timing of output video signals. Check uplink
encoder for that program.
Unrecoverable transition in incoming Program Clock Refer-
ence values. This has forced re-initialization of services.
Check uplink encoder for that program.
Formerly valid Program Map Table ceases to be received or
becomes corrupt. See "No PMT" indication.
Version number on one or more of the Program Map Tables
has changed but no change to PID lineup.
Some services available from satellite not routed to IRD
ASI output per program mapping instructions from
COMPEL . This is not necessarily a fault.
Selected program not available for local decompression
because this program content was blocked to ASI transport
output by network. Contact network TOC.
Program selected for local decompression (to local audio/
video outputs) not available-invalid Program number for
this Transport.
User-requested application failed self-test and Unit reverted
to Backup application. Notify your network TOC.
No carrier lock with RF signal power above specification
range. There may be too much line amplification in RF
feed.
Formerly valid Service Descriptor Table ceases to be
received or becomes corrupt. See "No SDT entry" indica-
tion.
Secure processor does not respond to local host or may be
missing. SIM card may be mis-installed, loose, or defective.
Unknown or miscellaneous hardware failure on serial port N.
Input buffer overflow on serial port N. Send device at
uplink may be set too fast compared to IRD serial port
device, especially if sending data constantly with only one
stop bit. Try changing to 1.5 stop bits.
Output buffer overflow on serial port N. Send device at
uplink may be set too fast compared to IRD serial port
device, especially if sending data constantly with only one
stop bit. Try changing to 1.5 stop bits.
