NOTE:
The section data communication channel (DCC), used for far
end communications, must be enabled at each network
element (shelf) optical interface being tested in order for the
end-to-end line tests to work. Default condition for the DCC
channel is "enabled". If it has been disabled, use the
set-fecom: command at each shelf to enable far end
communications.
At each shelf, use the set-fecom:address:com=enabled
command to ensure far end communications (fecom) is enabled.
9.
NOTE:
If option switch setting is changed, an update must be
performed by momentarily depressing the UPD/INIT button
on the SYSCTL after the OLIU is reinstalled.
Reinstall OLIUs (if removed) and connect each OLIU to the new
optical facility.
10.
NOTE:
Two or more shelves in the same network cannot have the
same system name or TID (set by the set-ne: command).
Verify no duplicate TID settings exist. The rtrv-ne: command
may be used at each shelf in the network to display settings. If
duplicates exist, determine new settings and use the set-ne:
command to make new settings.
