DDM-2000 OC-3 MULTIPLEXER
NOTE:
In a Stand-Alone DDM-2000 OC-1 ring application, the DDM-2000 OC-3
FiberReach host requires 26G2-U, 27G-U or 27G2-U OLIUs be installed
in the MAIN slots. The single-homed DDM-2000 OC-3/FiberReach ring
configuration requires that the FUNCTION UNITS-( )-1 OLIU on the
OC-3 host shelf connect to the MAIN-1 OLIU at the first FiberReach shelf
from the OC-3 host shelf. MAIN-2 OLIU at an adjacent 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 OC-3 host shelf.
NOTE:
A dual-homed ring configuration requires that the first FiberReach
MAIN-1 OLIU connect to FUNCTION UNITS-( )-1 OLIU on one host
OC-3 shelf. The last FiberReach MAIN-2 OLIU connects to the
FUNCTION UNITS-( )-2(P) OLIU on the other OC-3 host shelf.
Intermediate FiberReach shelves on the same OC-1 ring connect from
MAIN-2 OLIU at one FiberReach shelf to the MAIN-1 OLIU at an
adjacent FiberReach shelf (node).
NOTE:
The DDM-2000 OC-3 shelf OC-12 ring application requires 24G-U/24H-U
or 29G-U/29H-U OLIUsbeinstalledintheMAIN slots.
