5.
NOTE:
If fecom is enabled, an inconsistent DCC values alarm
will occur when the OLIUs are looped back. Normally, the
alarm occurs when the user/network parameters on the
OHCTLs at both ends of the DCC are set the same. To clear
the alarm during a fiber loopback, use the
set-fecom:
address
:com=disable command to disable
the DCC.
At host OC-3 shelf, connect optical loops for FUNCTION UNITS
OLIUs just installed.
6.
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. For example, see Figure 2.
Use the rtrv-fecom/set-fecom command to verify/set
Network Side/User Side parameters at each end of optical span
being established.
7. Use the rtrv-oc3/set-oc3 command at the host OC-3 shelf to
verify/set application (
app
) parameter for the OC-3 FUNCTION
UNITS slots being used for this OC-3 linear extension. For
example, set-oc3:fn-a,app=
1+1
.
8. Use the rtrv-oc3/set-oc3 command at the remote
FiberReach OC-3 shelf to verify/set application (
dcc
) parameter
for the OC-3 MAIN slots being used for this OC-3 linear extension.
For example,
set-oc3:main-1,dcc=
identical
and
set-oc3:main-2,dcc=
identical
.
9.
NOTE:
If line timing mode is specified or external timing mode is
specified but the timing reference was not available at the
host 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.
