Information provides backplane bus
termination, Telnet
connection to the node,
and shelf addressing, has
been physically pulled
from the backplane.
Could be Input signal strength is
Service degraded. Possibly a fiber
Affecting. problem or transmitter.

Check fiber path for damage or
bends and check attenuation
and transmitter output.
Check FTP connection and NE
status.
No suggestions.
Retrieve timing source
information and check reference
