Scope of work: The project consisted of the design and implementation of a network support system for the entire interlocking, for SCADA and telephone systems.

Scope of work: The Berryessa Extension is the 10-mile, two station, first phase of BART Silicon Valley. DAI had the opportunity to design, install, configure and commission the Fiber optic ring powered by CIENA provider grade Carrier Ethernet hardware and supported by Cisco level 3 switches with a complex method of service routing for increased traffic and security. DAI supplied the CCTV (supported by eXaqVision software), Access Control, PA and SCADA systems for the 2 stations that had each parking garages, buss stations and parking lot. These systems were subneted and interfaced with the operations and control center through the CWDM ring system powered by the CIENA infrastructure. DAI also supported the integration of TVM and Clipper Card Systems on the project.

Scope of work: The project consisted of the design and implement dual ring topology network for the entire station – powered by Cisco layer 3 switches. Design, configure and commission a Server based CCTV system supported by VERINT surveillance software, Access control system, Paging system with local and remote access for messages, support for networking for the Fire Alarm systems, TVM and Clipper Card Readers, and VMS units.

Scope of work: The project consisted of identification of links, full design of fiber optic cable splice and termination plan for the link span between the Oakland and San Francisco redundant generator systems, designs for the CCTV, Alarm and telephone systems on the projects, producing test procedures for these systems.

Scope of work: The project consisted of the network design and configuration for interlocation communication; Fiber Optic Systems designs; PC based local control panels design, build and integration with vital logic processors, that included the support for development of proper protocol for non-vital communication.

Scope of work: The project consisted of interconnecting the OCC and the Younger signal house through fiber optic links, this included fiber optic cable splicing and testing, then network systems configuration for remote access.

Scope of work: The project consisted of designing, installing and commissioning five systems for VTA in Santa Clara CA. The five systems were: The Fiber Optic Backbone Ring system, CCTV, Access Control, SCADA and PA. As part of the Project, DAI integrated all the projects that are tying into the backbone project, for seamless communication and access.
