NOTE:
Only
one
remote FiberReach OC-3 shelf is allowed in this
single-homed configuration.
NOTE:
A single-homed ring configuration requires that the
FUNCTION UNITS ( ) 1 OLIU
on the OC-12 shelf connect to
the
MAIN-1 OLIU
at the FiberReach OC-3 shelf. The
MAIN-2 OLIU
at the FiberReach shelf on the OC-3 ring
connects to
FUNCTION UNITS ( ) 2(P) OLIU
on the host
OC-12 shelf. See Figure 1. This procedure will establish the
ring configuration starting from the OC-12 host node to the
FiberReach OC-3 node, then from the FiberReach OC-3
node back to the host OC-12 node.
At the near end, remove the optical loop from the
OLIU
(for
example in Figure 1, Node 5 OC-12 shelf
FUNCTION UNITS A 1
)
associated with the optical span being established. At the other
end of the optical span, remove the optical loop from the
associated
28-Type
OLIU
(for example, in Figure 1, Node 7
FiberReach shelf
MAIN-1 OLIU
).
18.
NOTE:
The section data communication channel (DCC), used for far
end communications, must be enabled at each network
element (shelf) optical interface being tested in order for the
end-to-end line tests to work. Default condition for the DCC
channel is "enabled". If it has been disabled, use the
set-fecom: command
at each shelf
to enable far end
communications.
At each shelf, use the set-fecom:
address
:com=enabled
command to ensure far end communications (fecom) is enabled.
