Off-Air Ingress Plans

Off-Air Ingress Plans

The Off-Air Ingress plan provides the ability to define where to search for
off-air ingress in OneCheck and set the limits for pass/fail/warn
indications.
Off-air Ingress plans are used to designate which frequencies the ONX will
measure during the OneCheck test for ingress interferers in the
downstream frequency range. This ingress test is often used to find LTE
or terrestrial broadcast interferers on the Hybrid Fiber-Coax network.
Also, if a QAM carrier is in the band, the ONX uses its Ingress Under the
Carrier feature to see the noise floor below a QAM channel. If the
spectrum is vacant the ONX will look at the spectral response in the
band(s) to see if the limit is exceeded.
