6.
NOTE:
In dual homing configurations (Figures 8 through 11),
OLIU
circuit packs
must be installed in the correct slots in the host OC-12 nodes to support
the direction of traffic required. For example in Figures 8 and 9, for traffic
to be routed between Node 1 (See Figures 3 and 4) and the OC-3
system, the
21
or
22-Type OLIU
must be installed in
FUNCTION UNITS
group
A
,
B
,
C
, or
D
, slot
1
of Node 5 and
FUNCTION UNITS
group
A
,
B
,
C
, or
D
, slot
2(P)
of Node 4. This is required because traffic entering
Node 5, slot
FN-A-1
from the FiberReach shelf is automatically
connected to the
MAIN-B-1
(
MAIN 1
)
OLIU
when cross-connections are
made. Traffic entering slot
FN-A-2(P)
is automatically connected to the
MAIN-B-2
(
MAIN 2(P)
)
OLIU
.
In single homing or linear extension configurations (Figures 12 and 13),
the
21-Type OLIU
in
FUNCTION UNITS
group
A
,
B
,
C
, or
D
, slot
1
of the
OC-12 shelf must be connected to the
MAIN-1 OLIU
in the FiberReach
shelf. The
21-Type OLIU
in
FUNCTION UNITS
group
A
,
B
,
C
, or
D
,
slot
2(P)
of the OC-12 shelf must be connected to the
MAIN-2 OLIU
in
the FiberReach shelf.
Use the rtrv-eqpt: command at each node in the network to verify that
each shelf is properly equipped for the service being established. Ensure that
OLIU circuit packs are installed in the correct slots in the host OC-12 nodes.

NOTE:
Cross-connections supporting DS1 services are VT1.5
cross-connections in DDM-2000 FiberReach. Only STS-1
cross-connections are allowed in DDM-2000 OC-12. If STS1
cross-connections are made at a FiberReach shelf, there is a fixed
mapping of all 28 VT1.5 cross-connections to the function unit slots [see
ent-crs-sts1 command].
NOTE:
The following commands may be used to delete, enter, and retrieve
cross-connections: dlt-crs-vt1, dlt-crs-sts1, ent-crs-vt1 ,
ent-crs-sts1, rtrv-crs-vt1, and rtrv-crs-sts1. See the
"Commands and Reports" section of each system manual for a
description of commands .
