Installing a redundant backbone loop began with
the construction of the Primary Route (Phase 1), mostly
along the shoulder of US33 from the Metro Data Center
(MDC) in Dublin, shown in Figure 6, to the TRC in East
Liberty (Figure 7).
Both the Phase 1 and Phase 2 backbones were cabled
as home runs between the MDC and TRC locations. The
Local Route (Phase 2) followed a parallel path to US33
on various state and county roads, as well as passing
through the center of the city of Marysville and parts
of the city of Dublin.
The US33 Telecom Building in Figure 7 serves
as a small data center. It has two rooms and 19 data
cabinets for current and future network and electronics
to run the CAV systems. There will be more optical fiber
connections to this building in the future.
