7. What Release of software is installed in the system?
If Release 15 software is installed, continue with Step 8.
If Release 13 software is installed, proceed to Step 9.
8. Use the rtrv-oc3/set-oc3 or rtrv-oc12/set-oc12
command at the remote DDM-2000 OC-3 shelf to verify/set
application (dcc) parameter for the OC-3/OC-12 MAIN slots being
used for this OC-3/OC-12 linear extension. For example,
set-oc3:main-1,dcc=distinct and
set-oc3:main-2,dcc=distinct or
set-oc12:main-1,dcc=distinct and
set-oc12:main-2,dcc=distinct.
9.
NOTE:
This procedure will establish the OC-3 or OC-12 ring
configuration starting from one FT-2000 host node (far end)
to the first OC-3 or OC-12 node (near end), then continuing
to the next OC-3 or OC-12 node until the final connection is
made from the last OC-3 or OC-12 node to the other host
FT-2000 node.
NOTE:
The Network Side (NS)/User Side (US) parameters of the
DDM-2000 OC-3 or OC-12 set-fecom: command and the
FT-2000 DCC orientation must be set opposite at each end
of the optical spans. For example, see Figures 2 and 3.
Use the rtrv-fecom: command at the DDM-2000 to retrieve
DCC parameters. Use set-fecom:nsus=NS/US command at
the DDM-2000 to set Network Side (NS)/User Side (US)
parameters at each end of all optical spans being established.
Use the CONFIGURATION-Enter-Assignment-DCC command
at the FT-2000 to assign DCC channels.
10.
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.
