b. Traffic management center (TMC) communications
• The TMC connection shall support 10/100/1000 MBPS ethernet communication.
• The communications interface panel shall proxy all network requests that arrive on the TMC connection to avoid unwanted network traffic from reaching the broadband-over-power network between the communications interface panel and the video sensors.
• All communications to the video detection system through the TMC connection shall be to a single IP address.
• The system shall be able to provide full HD quality video through its wan port for use in streaming video back to the TMC or any remote location.
c. Local user communications
• A wired ethernet port shall be provided to connect the technician at the cabinet to the video detection system for setup and maintenance purposes.
o The maintenance port shall support 10/100/1000 MBPS ethernet communication.
o All communications to the video detection system through the maintenance port shall be to a single ip address.
o The maintenance port shall support DHCP to automatically assign an IP address to the user’s computer.
• An 802.11g wi-fi access point shall allow wireless connection to the video detection system at the cabinet for setup and maintenance purposes.
o All communications to the video detection system through the wi-fi access point shall be to a single IP address.
o The wi-fi access point shall support DHCP to automatically assign an IP address to the user’s computer.
o The wi-fi access point shall include a dipole, omnidirectional antenna.
o A momentary pushbutton shall allow the user to turn the wi-fi access point on or off.
o The wi-fi access point shall turn itself off automatically after a period of inactivity from connected devices.
o An led shall indicate when the wi-fi access point is enabled.
o The wi-fi access point shall operate simultaneously with the wired maintenance port and with the TMC connection.
o The Wi-Fi access point shall require a password for connection by a user’s computer.
the default password shall be changeable.
d. Traffic controller connection
• The traffic controller connection shall support a ts2 type 1 compatible SDLC interface.
o The traffic controller connector shall be a 15-pin female metal shell d sub-miniature type connector to support a standard NEMA ts2 or tees SDLC cable.
o The traffic controller connection shall support a protocol interface to SDLC-capable traffic controllers.
o The traffic controller connection shall support the NEMA ts2 SDLC protocol to include up to 64 detector outputs and 32 inputs.
• The traffic controller connection shall be able to connect to a wired input/output card, which supports wired i/o in cabinets without a SDLC-capable controller.
