Connecting Traffic Cabinets with 2-Wire Cabling using VDSL2
Antaira Technologies recently published a case study of a challenge faced by traffic engineers when upgrading outdated traffic signal communication systems that relied on 2-wire cabling from analog dial-up modems.
Seeking a cost-effective solution to enable Ethernet connectivity between four intersections, Antaira provided IVC-4011-T-V2 VDSL2 technology, which bridges Ethernet over existing 2-wire cabling, allowing for data transmission speeds of up to 100Mbps over distances of up to 0.75 miles.
This solution enhanced real-time monitoring, data logging, and central control operations, enabling efficient management of traffic signals, emergency vehicle preemption, and adaptive signal control without the need for extensive trenching.

ATSI Tester Software Updates
ATSI has released software updates for the PCMT 8000 and PCMT 8800.
The previous update stopped powering up the monitor at the beginning and end of the test run for all of the Caltrans and Canadian model 210/2010 monitors. The monitors are powered up to give the user a chance to change the switch settings on the monitor. It is unnecessary on these monitors because they all have DIP Switches or memory keys for the switch settings.
It is recommended that the switches be set prior to inserting the monitor into the cable enclosure.
Some customers need to clear the fault logs after the test is complete. This requires that the monitor have power applied. This update will add back in the power staying on at the end of the test. The power will still not be applied at the beginning of the test.
Having the monitor powered on presents the possibility that these monitors might be “hot-swapped” at the end of the test, potentially causing damage to the PCMT. Although the monitors may be able to be hot-swapped in the traffic cabinet, they should not be hot-swapped while using the PCMT.
