The Network Side/User Side parameters of the OC-3
extension set-fecom: command and the FT-2000 DCC
orientation must be set opposite at each end of the OC-3
optical spans. For example, see Figures 2 and 3.
Use the rtrv-fecom/set-fecom command at the DDM-2000
or the CONFIGURATION-Enter-Assignment-DCC command at
the FT-2000 to verify/set Network Side/User Side parameters at
each end of optical span being established.

8.
At FT-2000, verify/provision the FT-2000 low speed OC-3 slots
Protection Mode (from OC-3) Parameter to "1+1" if both slots are
used for the extension or to "0X1" if only one slot is used. (See
CONFIGURATION-Set-OC3 command in 365-575-103, FT-2000
