2. Verify system configuration is same as specified on work order or circuit order.
For example, see Figures 8 thru 13.
3. NOTE:
Cross-connections consist of drop and pass-through connections. For
example in Figures 8 and 11, drop connections are made at Nodes 1, 4,
and 5. Pass-through cross-connections are made at other nodes in the
network (Figures 2 and 4). Also, cross-connections must be made in all
interconnected rings, including other DDM-2000 OC-3 rings, DDM-2000
OC-12 rings, and FT-2000 OC-48 rings, as required. See
ent-crs-( )
command in the Commands and Reports section of Volume 1 of this
manual.
From work order or circuit order, determine the terminating (drop) nodes for
the service being established.
4. From work order, circuit order, and the sketch made in Step 1, determine the
pass-through nodes for the service being established.
5. From work order or circuit order, determine the host OC-12 node(s) that
connects to the OC-3 ring(s).
6. NOTE:
In dual homing configurations (Figures 8, 9, 11, and 12), 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 11,
for traffic to be routed between Node 1 (See Figures 2 and 4) and the
OC-3 system, the 21/22-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 OC-3 shelf is automatically
connected to the MAIN-B-1 OLIU when cross-connections are made.
Traffic entering slot FN-A-2(P) is automatically connected to the
MAIN-B-2 OLIU.
In single homing configurations (Figures 10 and 13), the 21/22-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 OC-3 shelf. The 21/22-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 OC-3 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.
