NOTE:
This single-homed ring configuration requires that the
FUNCTION UNITS-( )-1 OLIU on the OC-3 shelf connect to
the MAIN-1 OLIU at the first FiberReach shelf from the OC-3
shelf. MAIN-2 OLIU at the FiberReach shelf (node) connects
to the MAIN-1 OLIU at an adjacent FiberReach shelf (node).
The MAIN-2 OLIU at the last FiberReach shelf on the OC-1
ring connects to FUNCTION UNITS-( )-2(P) OLIU on the
host OC-3 shelf. See Figure 1. This procedure will establish
theringconfigurationstartingfromtheOC-3orOC-12host
node (near end) to the first FiberReach node, then
continuing to the next node until the final connection is made
from the last FiberReach node back to the host OC-3 or
OC-12 node.
NOTE:
All unused ports on the 27G-U/27G2-U OLIU must be set to
nmon with the set-state-oc1 command.
At the near end, remove the optical loop from the 26G2-U, 27G-U
or 27G2-U OLIU OC-1 line (1 or 2)(forexampleinFigure1,OC-3
shelf FUNCTION UNITS-A-1, OC-1 line 1) associated with the
optical span being established. At the other end of the optical
span, remove the optical loop from the associated OLIU (for
example, in Figure 1, FiberReach MAIN-1 OLIU).
11.
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.
DLP-51412. Perform optical fiber connections and verification of the integrity of
the optical span being established.
