Cable AML has implemented a full digital upstream upgrade to an existing 54 to 550 MHz downstream AML System. The upgrade allows full bi-directional cable service in areas that are expected to generate significant income growth, because marketing studies showed that DOCSIS Modem service and Set Top Box interactivity were important issues for increasing revenue.
The existing downstream system consisted of a transmitter at Sedona ( Arizona) delivering signals to five remote sites via a repeater array at Mingus Mountain. Cable AML designed the upgrade and assisted in the installation and turn-on.
Upstream capability was implemented without the need to change or add to the existing antennas. Local and remote transceivers were implemented by using existing receivers, originally purchased form another company, thus saving NPG tens of thousands of dollars.
