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 8-8, 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
1. 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.
2. At DDM-2000 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 transient alarms during provisioning.
