NOTE:
This procedure will establish the OC-3/OC-12 ring
configuration starting from the WaveStar TDM 2.5G host
node (far end) to the first OC-3/OC-12 node (near end), then
continuing to the next OC-3/OC-12 node until the final
connection is made from the last OC-3/OC-12 node back to
the host WaveStar TDM 2.5G node.
NOTE:
The Network Side (NS)/User Side (US) parameters of the
OC-3/OC-12 set-fecom: command and the WaveStar
TDM 2.5G DCC orientation must be set opposite at each
end of the optical spans. For example, see Figure 2.
Use the rtrv-fecom/set-fecom command at the DDM-2000
or the Enable/Disable DCC Terminations, T 305, procedure at
the WaveStar TDM 2.5G to verify/set Network Side/User Side
parameters at each end of all optical spans being established.
7.
NOTE:
If line timing mode is specified or external timing mode is
specified but the timing reference was not available at the
OC-3 shelf turnup, the TGS/TG3 option switches are
probably set for free running . Before this configuration is
established, the specified timing mode must be set on the
TGS/TG3 circuit packs.
NOTE:
If the option switch setting is changed, an update must be
done by momentarily depressing the UPD/INIT button on the
SYSCTL after the TGS/TG3 circuit packs are reinstalled.
