5.
NOTE:
The rtrv-oc3: command retrieves the OC-3 Line
Provisioning Report. This report lists information
about each OC-3 line. This information includes attributes
set by the OC-12 set-oc3: command. The applications
(app) parameter of the set-oc3 command must be set to
1+1 for the FUNCTION UNITS slots being used for the OC-3
extension in the OC-12 shelf. See the Commands and
Reports section of 363-206-295,
DDM-2000 OC-12
Multiplexer, TARP Release 7, User/Service Manual—
Volume I
for a description of the rtrv-oc3: command
format.
Use the rtrv-oc3/set-oc3: command at the OC-12 shelf to
verify/set the applications parameter to 1+1. (For example,
set-oc3:fn-{a,b,c,d,all},app=1+1)
6.
NOTE:
DDM-2000 OC-3 shelves must be connected through the
MAIN or FUNCTION UNITS C slots if the shelf or network is
deriving timing from the OC-3 optical links to the OC-12
network. See description of the src parameter in
set-sync: command in 363-206-285,
DDM-2000 OC-3
Multiplexer, TARP Release 13 and Later, User/Service
Manual—Volume I
.
Ensure the DDM-2000 OC-3 subnetwork and/or shelf has been
properly equipped with OLIUs to accept the new OC-3 optical
extension.
7. Determine the optical loss of the optical facility from office records
or by making the required measurements.
8.
NOTE:
The Network Side (NS)/User Side (US) parameters of the
set-fecom: command must be set opposite at each end of
the optical spans.
Use the rtrv-fecom/set-fecom command to verify/set
Network Side/User Side parameters at each end of optical span
being established. See Figure 2.
