Example Cross-Connections
8
To establish the end-to-end DS1 circuit from the CO to the DDM-2000 FiberReach
wideband shelf as shown in Figure 8-2, enter a cross-connection at each node as
follows:
â–
At RT1, RT2, and RT4:
ent-crs-vt1:m-1-2-3,m-1-2-3:cct=twoway;
The VT signal passes through these sites on the OC-3 ring, so two-way
cross-connections with identical addresses are provisioned here.
â–
At RT3:
ent-crs-vt1:m-1-2-3,b-1-5-4:cct=twoway;
This single command establishes the following signal paths through the
DDM-2000 OC-3 shelf at RT3:
— from Main-1, STS-1 #1, VTG #2, VT1.5 #3
to FN-B-1, STS-1 #1, VTG #5, VT1.5 #4
— from FN-B-1, STS-1 #1, VTG #5, VT1.5 #4
to Main-1, STS-1 #1, VTG #2, VT1.5 #3
— from Main-2, STS-1 #1, VTG #2, VT1.5 #3
to FN-B-2, STS-1 #1, VTG #5, VT1.5 #4
— from FN-B-2, STS-1 #1, VTG #5, VT1.5 #4
to Main-2, STS-1 #1, VTG #2, VT1.5 #3
â–
At the CO:
ent-crs-vt1:m-1-2-3,b-7-4:cct=twoway;
This is a "drop" from the OC-3 ring to a DS1 interface.
â–
At FiberReach:
ent-crs-vt1:m-1-5-4,c-1-1:cct=twoway;
This is a "drop" from the OC-1 ring to a DS1 interface.
It is recommended that the pass-through cross-connections be entered first, as
shown here, to avoid transit alarms during provisioning.
