Metropolitan Transportation Authority (MTA)

DVI excels in its depth-of-knowledge in the integration of many discrete technologies – integration is often a requirement these days, including integration of voice, wireless, mobility, surveillance, and sensor-support.


For the Metropolitan Transportation Authority the project encompassed the relocation of approximately 7,000 people to a 1.6 million sq. ft. gut-renovated facility.
The project was “fast-tracked”: The management of the project mandated that design through implementation of the first phase covering all building systems, computer facilities, etc. and 4,000 employees to be completed in less than 12 months. Specific systems were developed to serve particular departments and divisions. These included a 3,500-node LAN for NYC Transit and an 800-
node LAN for Bridges & Tunnels. Due to differing considerations, a Nortel network with ATM backbone was set up for NYCT, and a Cisco network with high-speed Ethernet was similarly designed & deployed for Bridges and Tunnels. The project also required redundancy and fail-safe schemes for network and server connectivity,
and a network-monitoring
infrastructure that was designed utilizing Network Associates’ distributed snifters (for NYCT). Similar considerations and deployments were
made for the MTA’s telephony systems, which included a CO grade Nortel DMS100 with a 20,000-line capacity and a 200 position ACD system with IVR, VRU and voice recording. DVI furthermore reviewed and contributed to the project’s base building specifications. These included power back-up, HVAC, UPS, 5 megawatts of diesel power, and so on.
