The ATC-QCOMM modem connects to Bell 202 modems. It has an Ethernet port which allows it to transmit this modem traffic over an IP network. This can mitigate the need for expensive leased lines.
This device also works in traditional closed loop traffic control systems and allows up to four independent communication lines capable of operating in a multi-drop environment. This will allow up to 32 different traffic signal controllers to be connected to a master, whether that master is located in the field or co-located in the central office.
The unit comes as a standard plug-in module for Luxcom’s ATC3 Traffic Controller, or it can be can be ordered in a stand-alone case.
