1 1993 Specifications CSJ SPECIAL SPECIFICATION 1303 Lifelink 1. Description. This Item shall govern for the furnishing and installation of LifeLink equipment in Fiber Hubs (existing and proposed) and on all associated overhead sign bridge supports and camera support structures and in the TransGuide Operations Control Center as shown on the plans, as detailed in these Special Specifications and as directed by the Engineer. 2. General. The existing LifeLink System provides a distributed mobile Local Area Network (LAN) designed to link San Antonio Fire Department (SAFD) ambulances on or near San Antonio's freeway system with a hospital in the city. The link utilizes the facilities and roadside fiber-optic network of the TransGuide Advanced Traffic Management System (ATMS) to establish a communication link between a mobile ambulance and a hospital. The LifeLink System utilizes this mobile LAN communication network to conduct real-time video conferencing between an ambulance and a physician at the hospital. Additionally, the ambulance crew can use portable medical data instruments to send vital statistical data to terminal equipment in the hospital over this same mobile LAN network. The LifeLink Sytem utilizes a standard Ethernet LAN protocol that enables the use of Simple Network Management Protocol techniques for network management of configurable system devices. The proposed LifeLink equipment shall be fully compatible with existing LifeLink hardware and software. LifeLink equipment provides a communications interface between the ambulance and TransGuide Operations Control Center. LifeLink equipment shall be added to fiber hubs, video camera locations and in the TransGuide Operations Control Center which will provide for a communications link capable of supporting data transmission between an ambulance radio and the fiber hub radio to TransGuide. LifeLink radios with an Ethernet port, antenna, lighting arrester, and enclosure will be mounted on existing TransGuide camera poles and on existing overhead sign bridges. The Ethernet transceivers, half-to-full duplex converters, and wave division multiplexer with all incidentals shall be installed in existing and proposed fiber hubs and in the Control Center. The wave division multiplexers shall separate/combine the TransGuide SONET (1310nm) and LifeLink Ethernet(1550nm) data that is being multiplexed on the TransGuide protect fiber optic cable pair. 3. Materials. (1) General Requirements. All materials furnished, assembled, fabricated or installed under this Item shall be fully compatible with TransGuide existing hardware and

Incidentals (as required) One LifeLink unit consists of all equipment shown above and installed per fiber hub location including associated equipment installed at TransGuide Control Center (see LifeLink Block Diagram). (2) Wave Division Multiplexer. A pair of wave division multiplexers shall be installed at each fiber hub. The multiplexers shall be placed on a retractable shelf furnished and installed by the Contractor. Shop drawings shall be submitted to the Engineer for approval. One multiplexer shall be used to multiplex the TransGuide bound 1310nm data and 1550nm LifeLink optical data. The second multiplexer is used to de-multiplex the fiber hub bound 1310nm TransGuide data and 1550 nm LifeLink data. The TransGuide protect fiber optic cable pair (Tx and Rx fibers) between the fiber hub panel and OC-3 MUX shall be routed between the wave division multiplexers and the OC-3 MUX. A new fiber optic pair shall be installed between the panel and wave division multiplexers to complete the original path. Another new fiber optic cable pair shall be installed to connect the wave division multiplexer 1550nm ports to the LifeLink fiber optic transceiver. A pair of wave division multiplexers shall be installed at the TransGuide Operations Control Center. One multiplexer is used to multiplex the TransGuide OC nm

3 transmit data and LifeLink 1550nm transmit data onto one fiber running to the fiber hub. The other multiplexer is used to de-multiplex the composite 1310nm and 1550nm data from the fiber hub back into separate 1310nm data for the TransGuide OC-3 receiver input and 1550nm data for the LifeLink receiver input. In order to accomplish this, the protect fiber optic cable pair that used to run between the lightguide distribution shelf and the OC-3 MUX shall be rerouted between the wave division multiplexer and OC-3, and a new fiber optic cable pair shall be installed between the lightguide distribution shelf and the wave division multiplexer to re-establish the original communication link. Another new fiber optic cable pair shall be installed to extend the LifeLink 1550nm data between the wave division multiplexer and the LifeLink Ethernet switching equipment. The wave division multiplexer shall meet the following requirements: Passband: 1295 to 1325, 1535 to 1565nm Fiber Type: Single Mode as stated in Special Specification Fiber Optic Cable (Single Mode) Typ.
