ADDENDUM 2 Technical Questions and Answers

RFP-DOT-9047-GH FL KEYS ITS MICROWAVE SYSTEM

1. The RFP states that the use of Cat B dishes is allowed for spur paths. Being that this area is in a very poor propagation region, there is a concern of using 18 and 23 GHz frequencies. Is it acceptable to the FDOT to change any of the spur paths that are designated as 18 or 23 GHz in the Appendix to 11GHz with 2' Cat B2 dishes? RESPONSE: No. Proposers are required to comply with all specifications of this RFP.

2. Section 4.3.1 states that the radio must support a minimum bandwidth of 40MHz. Must the design include using 40MHz or greater channels, or is the requirement just that the radios must be capable of 40MHz or greater channels if ever needed? RESPONSE: The design must use 40 MHz or greater channels as appropriate for the FCC licensed channel. Proposers are required to comply with all specifications of this RFP.

3. Section 4.3.1 states that the radio must support adaptive modulation up to 2048 QAM.

Must the design include using adaptive modulation, or is the requirement just that the radios must be capable of adaptive modulation up to 2048 QAM if ever needed? RESPONSE: The design must use 2048 QAM adaptive modulation as appropriate for the FCC licensed channel. Proposers are required to comply with all specifications of this RFP.

4. On the Key ITS Carrier Ethernet Architecture drawing, two fiber paths are shown

extending from site GG to RTMC. One of the paths bypasses the Terremark NAP and one of them passes through it. Is the NAP pass-through a glass-through, or does it pass through equipment at the NAP? If so, what equipment? RESPONSE: DELETE and remove entirely Sheet No. IT-8, KEYS ITS CARRIER ETHERNET ARCHITECTURE, from the Exhibit A Technical Specifications, Appendix A – FDOT FLORIDA KEYS ITS MICROWAVE SYSTEM CONTRACT PLANS. Strike-out Sheet No. line: “IT-8 –CARRIER ETHERNET ARCHITECTURE”, INDEX OF PLANS, on KEYS MICROWAVE KEY SHEET, Sheet No. IT-1.

5. On the Key ITS Carrier Ethernet Architecture drawing, there are two solid black 500 Mbps lines extending from the AT&T Metro Ethernet cloud: one to the NAP and one to the RTMC. This looks like the single 500 MBPS path shown from the AT&T Metro Ethernet Cloud to the RTMC on the Proposed System Design Overview drawing. Does the 500 MBPS actually terminate at the NAP? What equipment does it pass through at the NAP to become part of the traffic on the fiber link extending from the NAP to RTMC? RESPONSE: DELETE and remove entirely Sheet No. IT-8, KEYS ITS CARRIER ETHERNET ARCHITECTURE, from the Exhibit A Technical Specifications, Appendix A – FDOT FLORIDA KEYS ITS MICROWAVE SYSTEM CONTRACT PLANS. Strike-out Sheet No. line: “IT-8 –CARRIER ETHERNET ARCHITECTURE”, INDEX OF PLANS, on KEYS MICROWAVE KEY SHEET, Sheet No. IT-1.

6. On the Key ITS Carrier Ethernet Architecture drawing, the Key West Ring is shown from

site W through sites R-V to site Q. On the Proposed System Design Overview drawing, the path from W to Q appears to be a linear radio path. How is the Key West logical ring to be implemented over the linear radio topology from W to Q? RESPONSE: DELETE and remove entirely Sheet No. IT-8, KEYS ITS CARRIER ETHERNET ARCHITECTURE, from the Exhibit A Technical Specifications, Appendix A – FDOT FLORIDA KEYS ITS MICROWAVE SYSTEM CONTRACT PLANS. Strike-out Sheet No. line: “IT-8 –CARRIER ETHERNET ARCHITECTURE”, INDEX OF PLANS, on KEYS MICROWAVE KEY SHEET, Sheet No. IT-1.

7. On the Key ITS Carrier Ethernet Architecture drawing, the Tea Table Ring is shown from site M through sites N-P and I-L to site F. On the Proposed System Design Overview drawing, the path from I to F appears to be a linear radio path. How is the Tea Table logical ring to be implemented over the linear radio topology from I to F? RESPONSE: DELETE and remove entirely Sheet No. IT-8, KEYS ITS CARRIER ETHERNET ARCHITECTURE, from the Exhibit A Technical Specifications, Appendix A – FDOT FLORIDA KEYS ITS MICROWAVE SYSTEM CONTRACT PLANS. Strike-out Sheet No. line: “IT-8 –CARRIER ETHERNET ARCHITECTURE”, INDEX OF PLANS, on KEYS MICROWAVE KEY SHEET, Sheet No. IT-1.

8. On the Key ITS Carrier Ethernet Architecture drawing, the US-1 Ring East Ring and Card Sound Rd Ring West rings both start by connections from site Q to site F There are no direct connections from site Q to Site F. To get to F, it appears on the Proposed System Design Overview drawing that you will have to pass through all of the microwave radios from Q through P-I to F. Is this interpretation correct? RESPONSE: DELETE and remove entirely Sheet No. IT-8, KEYS ITS CARRIER ETHERNET ARCHITECTURE, from the Exhibit A Technical Specifications, Appendix A – FDOT FLORIDA KEYS ITS MICROWAVE SYSTEM CONTRACT PLANS. Strike-out Sheet No. line: “IT-8 –CARRIER ETHERNET ARCHITECTURE”, INDEX OF PLANS, on KEYS MICROWAVE KEY SHEET, Sheet No. IT-1.

9. On the Key ITS Carrier Ethernet Architecture drawing, the US-1 Ring East Ring and Card Sound Rd Ring West rings both start by connections from site Q to site F, and the two rings pass through most of the same nodes. Are these two logical rings to be mapped over the same physical ring topology, except that the US-1 Ring East Ring terminates on B and the Card Sound Rd Ring West ring terminates on D? RESPONSE: DELETE and remove entirely Sheet No. IT-8, KEYS ITS CARRIER ETHERNET ARCHITECTURE, from the Exhibit A Technical Specifications, Appendix A – FDOT FLORIDA KEYS ITS MICROWAVE SYSTEM CONTRACT PLANS.

10. On the Key ITS Carrier Ethernet Architecture drawing, the RTMC Access Ring encompasses sites A through HEFT to RTMC. On the Proposed System Design Overview drawing, the path from A to HEFT appears to be a linear radio path, and the path from HEFT to RTMC is a point-to-point fiber path. But, there doesn't appear to be a direct return path from RTMC to A. It appears that to close the RTMC Access Ring, the traffic will have to pass from RTMC to the AT&T Metro Ethernet cloud over the 500 Mbps radio path and then from the cloud to site A over the 10 Mbps radio path to site A. Is this interpretation correct? RESPONSE: DELETE and remove entirely Sheet No. IT-8, KEYS ITS CARRIER ETHERNET ARCHITECTURE, from the Exhibit A Technical Specifications, Appendix A – FDOT FLORIDA KEYS ITS MICROWAVE SYSTEM CONTRACT PLANS. Strike-out Sheet No. line: “IT-8 –CARRIER ETHERNET ARCHITECTURE”, INDEX OF PLANS, on KEYS MICROWAVE KEY SHEET, Sheet No. IT-1.

11. On the Key ITS Carrier Ethernet Architecture drawing, all of the logical access rings are shown daisy-chained together. Is this drawing intended to show how the traffic from each of the logical access rings gets mapped to RTMC over the physical microwave network topology? Is the AT&T Metro Ethernet cloud supposed to provide the ring closures in those cases where the physical topology is mostly linear except for the extensions from some of the sites to the AT&T cloud? The logical Access rings don't seem to match up with the physical topology of the network, which is confusing. RESPONSE: DELETE and remove entirely Sheet No. IT-8, KEYS ITS CARRIER ETHERNET ARCHITECTURE, from the Exhibit A Technical Specifications, Appendix A – FDOT FLORIDA KEYS ITS MICROWAVE SYSTEM CONTRACT PLANS. Strike-out Sheet No. line: “IT-8 –CARRIER ETHERNET ARCHITECTURE”, INDEX OF PLANS, on KEYS MICROWAVE KEY SHEET, Sheet No. IT-1.

12. On the Proposed System Design Overview drawing, the Carrier Ethernet traffic into the HEFT site appears to consist only of one 18GHz microwave radio link into HEFT. The other two 500 Mbps links from the AT&T Metro Ethernet network already terminate directly at RTMC. Is it fair to say that the only traffic that needs to be carried over the Point-to-point optical (1830 PSS) connection from HEFT through CR to RTMC is the Carrier Ethernet payload from the 18 GHz radio link terminating at HEFT from Site A? RESPONSE: The traffic carried over the 18 GHz link at the HEFT and onward through CR to the RTMC includes all traffic emanating from all ITS devices participating in the entire network’s Carrier Ethernet multi-ring topology, depending on traffic engineering, loading and protection switching scenarios.
