There are roughly 4,500 Pulsecom PCAUs now supporting telco STL links nationwide, the supplier says, but phone companies have not been able to deliver the 20 Hz - 20 kHz service level required by HD Radio and stations that want optimum signal quality, according to the supplier.

To address this issue, Pulsecom said it is introducing the HD PCAU. The unit, Pulsecom says, continues to avoid MPEG signal corruption and introduces minimum delay to enable real time monitoring; it also adds apt-X 20 Hz to 20 kHz audio, an in-band RDS data link and compatibility with existing PCAUs.

This means transitioning from analog to digital or from 15 kHz to 20 kHz can be done at each end of a link as time and budgets permit rather that via a costly and risky flash cut, the supplier states.

Concerns about malicious Internet attacks are eliminated by using nailed up telco private lines. Pulsecom also says HD PCAU provides faster, easier, backward-compatible operation during earthquakes; second-level outdoor lightning; and airborne contaminants protection.
