Ingress/Noise Mitigation Test Process
Test process with only spectrum mode on meter
✓
Ingress/noise in the upstream path is very common and impacts subscriber services
✓
Ingress/noise can be constant, or intermittent
✓
If ingress/noise is constant, and tech fixes an issue at a local test point, did that clean up the
ingress/noise received in the headend, or is there still another issue at some other point in the
network?
✓
If ingress is intermittent, and spectrum is clean, tech doesn't know whether there is no ingress at
this particular point, or the ingress isn't happening at this time
✓
Meter spectrum mode enables tech to test upstream spectrum only at their local test point
Test process with Field
View, the technician can compare with local test point, know if
intermittent ingress is active at time of test, or if repaired issue was root cause of ingress/noise
✓
Meter displays headend upstream spectrum view as measured by XPERTrak PathTrak
equipment
✓
Techs see cumulative ingress coming from the field and reaching the headend
✓
When performing ingress mitigation the user in the field can quickly verify if actions being taken
are helping or if additional effort is needed to reduce the ingress coming into the plant
✓
Field View option can be added to any new or current ONX
✓
New unit option part #: ONX-CATV-SW-FV
✓
Option upgrade part #: UPG-ONX-CATV-SW-FV (field upgrade)
