The Sound Transit Link two-way radio system now operates over the existing King County Regional 800 MHz Trunked Radio System (“KCRS”), using Motorola mobile radios, portable radios, and control stations configured for operation on the KCRS, which is a Motorola Smartzone analog trunked radio system operating with Version 4.1. The KCRS will be migrating over the next 5 years to a replacement system called PSERN (Puget Sound Emergency Radio Network), which will be a Motorola P25 Phase 2 system that will be interconnected to other P25 systems in the Puget Sound Region via ISSI 8000. By the time the DAS systems described in these specifications are implemented, the PSERN system should be essentially fully implemented as a two-slot TDMA radio system, and the systems described in these specifications will operate over the PSERN system. Therefore, there will be two voice paths per 12.5 kHz RF channel at each base station facility in the system, and the systems described in these specifications will operate over the PSERN system. 2. Mobile and portable radios for the Sound Transit two-way radio system will be provided by others and under a separate contract and are not the responsibility of Contractor in these Specifications. These radios will be programmed by others to operate on the PSERN system. B. NORTH LINKNORTHGATE LINK TUNNEL RADIO SYSTEM 1. The existing above-ground repeater sites in the future PSERN system willsystem will provide coverage to the portions of the Sound Transit North LinkNorthgate Link alignment that are above ground (as does the existing KCRS system), while a new Tunnel Radio System will be implemented to provide NORTHGATE / EAST LINK SECTION 27 60 02 RTA/AE 0027-12 EXTENSIONS TUNNEL RADIO SYSTEM N830 / E750 SYSTEMS ENGINEERING IFC 09/11/2018 - CNRFP#007 & #008 11/24/2017 CNRFP-016 11/27/2017 CNRFP-017 12/11/2017 CNRFP-021 02/07/2018 CO #007 02/15/2018 CNRFP-018 03/20/2018 – CO#008 03/21/2018 – CO#009 04/27/2018 – CO#010 & 012 09/07/2018 – CNRFP-052 PAGE 2 OF 86 Addendum 5.2 coverage in the North LinkNorthgate Link tunnel segments and three new stations at U-District Roosevelt, and Northgate. 2. The North LinkNorthgate Link DAS System described in these Specifications will provide radio communications for Sound Transit trains, and public safety agencies (Seattle Police, Seattle Fire, and EMS) in a new tunnel now being constructed from the University of Washington Campus to Northgate. The Distributed Antenna System shall provide coverage in the tunnel bore segments and in all public and all habitable ancillary spaces in the three stations, including: a. Electrical rooms b. Comm. Rooms c. Elevators d. Crew resting areas 3. The North LinkNorthgate Link Distributed Antenna System will be fed by the 800 MHz dual-redundant base station site located at the Sound Transit Operations and Maintenance Facility (“OMF”), which will be upgraded to be part of the PSERN P25 system. This base station site now operates as part of the KCRS. That base station facility will be connected via redundant path RF-over-fiber links to RF distribution hubs located at the U-District and Roosevelt Stations in the North LinkNorthgate Link Segment. The RF distribution hubs will feed 800 MHz signals from the PSERN system to hybrid radiating cable/distributed antenna systems in the stations and tunnel bore segments. 4. The Northgate Station Distributed Antenna System will be fed with a fiber-fed remote repeater unit; the remote unit will be fed from the Northgate Parking Garage (described below). 5. In addition to the fiber-fed DAS system described above, the parking garage at the Northgate Station will incorporate a separate DAS system fed via an off-the- air donor antenna. 6. The existing base station at the Sound Transit OMF facility is an existing and operational system which will be modified by others to incorporate it into the PSERN system. This base station facility is also not the responsibility of the Contractor. 7. The North LinkNorthgate Link Tunnel Radio System includes two conventional 800 MHz repeaters in each tunnel segment operating on 8TAC (International Tactical Channel) interoperability channels to provide backup communications in the tunnels in the event of the complete failure of both the main and the backup base station repeater sites or failure of one or both of the fiber links between the base station repeater sites and the tunnel segments. (8TAC channels are public safety 800 MHz conventional channels reserved for use by multiple agencies as interoperability channels and tactical channels.) One repeater provides backup communications for public safety users. The other repeater provides backup NORTHGATE / EAST LINK SECTION 27 60 02 RTA/AE 0027-12 EXTENSIONS TUNNEL RADIO SYSTEM N830 / E750 SYSTEMS ENGINEERING IFC 09/11/2018 - CNRFP#007 & #008 11/24/2017 CNRFP-016 11/27/2017 CNRFP-017 12/11/2017 CNRFP-021 02/07/2018 CO #007 02/15/2018 CNRFP-018 03/20/2018 – CO#008 03/21/2018 – CO#009 04/27/2018 – CO#010 & 012 09/07/2018 – CNRFP-052 PAGE 3 OF 86 Addendum 5.2 communications for Sound Transit personnel. The Sound Transit conventional repeater will be linked to the Sound Transit control center via dedicated audio and control links over the Sound Transit communications backbone system. C. EAST LINK TUNNEL RADIO SYSTEM 1. The existing above-ground repeater sites in the future PSERN system will provide coverage to the portions of the Sound Transit East Link alignment that are above ground, while new DAS Systems will be implemented to provide coverage in the East Link I-90 tunnel segments, in the Bellevue Transit Center tunnel and station, in the Winter House Lid, in the 112th Street Underpass, and in the other facilities described in these specifications. 2. The East Link DAS System described in these Specifications will provide radio communications for Sound Transit trains, and public safety agencies (Mercer Island, Bellevue; and Redmond Police, Mercer Island, Bellevue and Redmond Fire; and Mercer Island, Bellevue and Redmond EMS) in a new tunnel segments and in multiple stations to be constructed from the existing IDS station on Central Link to Overlake Transit Center in Redmond. The Tunnel Radio System shall provide coverage in the East Link primary tunnel bore segments: Bellevue Transit Center, Mount Baker I-90 and Mercer Island I-90 Lid) and in all public and required habitable ancillary spaces (including electrical rooms, communications rooms, elevators, crew resting areas and in the TPSS buildings and signal houses listed herein) in the following stations and short tunnel segments (the type of system feed and headend location for each of these facilities are listed for each station or tunnel segment): a.
