Both rotations of each of the two OC-1 rings terminate on a pair of 27G2-U
OLIUs placed in the Function Unit A. More specifically, the inner OC-1 ring
terminates on the OC-1 #1 ports of the 27G2-U OLIUs, and the outer OC-1
ring terminates on the OC-1 #2 ports of the 27G2-U OLIUs.
Example Cross-Connections
8
In order to cross-connect each rotation of one ring to the corresponding
rotation of the other ring, Single-Homed OC-1 Ring Hairpin Routing would
consist of the following cross-connections.
To establish the end-to-end DS1 circuit between Node RT-B and RT-A
through the Host as shown in Figure 8-5, enter a cross-connection at each
node as follows:
■
At Node Host, enter the following cross-connection:
ent-crs-vt1:a-1-7-4,a-2-4-1:cct=twoway;
This single command establishes the following signal paths through the
Function Unit A of the OC-3 shelf:
— from FN-A-1, STS-1 #1, VTG #7, VT1.5 #4
to FN-A-1, STS-1 #2, VTG #4, VT1.5 #1
— from FN-A-1, STS-1 #2, VTG #4, VT1.5 #1
to FN-A-1, STS-1 #1, VTG #7, VT1.5 #4
— from FN-A-2, STS-1 #1, VTG #7, VT1.5 #4
to FN-A-2, STS-1 #2, VTG #4, VT1.5 #1
— from FN-A-2, STS-1 #2, VTG #4, VT1.5 #1
to FN-A-2, STS-1 #1, VTG #7, VT1.5 #4
■
At Node RT-B, enter the following cross-connect:
ent-crs-vt1:m-1-7-4,a-1-1:cct=twoway;
■
At Node RT-A, enter the following cross-connect:
ent-crs-vt1:m-1-4-1,b-1-3:cct=twoway;
