the Low-Speed slots. Both rotations of the OC-1 ring terminate on a pair of
27G2-U OLIUs placed in Function Unit A of the OC-3 (HOST) node. More
specifically, the OC-1 ring terminates on the OC-1 # 2 ports of the 27G2-U
OLIUs.
By establishing VT1.5 Hairpin local drop cross-connects between FN-A
and FN-C of the OC-3 Host node, the user is allowing traffic to be routed
from the FiberReach RT-A node in the OC-1 ring to a local drop on the
OC-3 Host node without using bandwidth on the OC-3 ring.
Example Cross-Connections
8
To establish the end-to-end DS1 circuit between Node HOST and RT-A as
shown in Figure 8-7, enter a cross-connection at each node as follows:
■
At Node HOST, enter the following cross-connection:
ent-crs-vt1:a-1-2-4,c-2-4:cct=twoway;
This single command establishes the following signal paths through the
OC-3 shelf:
— from FN-A-1, STS-1 #1, VTG #2, VT1.5 #4
to FN-C, VTG #2, VT1.5 #4
— from FN-A-2, STS-1 #1, VTG #2, VT1.5 #4
to FN-C, VTG #2, VT1.5 #4
■
At Node RT-B, enter the following cross-connection:
ent-crs-vt1:m-1-2-4,m-1-2-4:cct=twoway;
It is recommended that the user enters the pass-through cross-connects
first.
■
At Node RT-A, enter the following cross-connection:
ent-crs-vt1:m-1-2-4,a-1-1:cct=twoway;
