City of Santa Ana <br />Local Signal Synchronization Plan <br />City plans to relocate the existing Main TMC facility and systems into the Annex Building. This <br />will allow the City to decommission the existing Remote TMC (RTMC) and centralize its traffic <br />operations and related systems within a new Main TMC. The new Main TMC is to be relocated <br />to the same floor space and operations area as all traffic engineering personnel. <br />The TMC systems communicate to the entire traffic network through seventeen (17) separate <br />fiber optic legs. Each cable is terminated on 1 of 3 FDUs (Fiber Distribution Units) housed in the <br />TMC server racks. These (17) communication legs are all landed on a Layer 3 Ethernet Switch <br />which acts as the central gateway on the network. An image of the TMC equipment room is <br />shown in Figure 4. <br />VL�j����gtl <br />S <br />Figure 4 — City of Santa Ana TMC Equipment Room <br />with the City's future plans to move the Main TMC into the Annex Building, allowing the City to <br />decommission the Remote TMC, an opportunity exists for upgrading these systems rather than <br />attempting to move and re -use them. <br />Page 9 1 2023 <br />
