 The PathTrak Return Path Monitoring System offers a highly efficient, continuous, and automated method of monitoring and analyzing RF performance ideal for operators who currently, or who are planning to, deploy advanced services such as VoIP.
The architecture uses distributed scanning spectrum analyzers with advanced network-based software.
Analysis tools allow cable operators to quickly troubleshoot issues before they impact the customer. Simultaneously, PathTrak's ability to communicate with the SDA and DSAM field meters (Field View option) lets technicians view the live headend return spectrum to quickly find and fix return ingress problems.
PathTrak is the only Return Path Monitoring System available that is fast enough and powerful enough to simultaneously provide monitoring, live remote client spectrum views, constant performance history, and remote spectrum views on field meters (Patent No. 6,425,132).
The PathTrak Return Path Monitoring System continuously monitors the upstream noise and carrier levels returning from multiple nodes.
As many as 1500 or more nodes may be monitored on a single PathTrak server without any sacrifice in performance. Each PathTrak server can be scaled to handle up to 30 remote clients simultaneously.
The management of all nodes on a single system is greatly simplified with highly sophisticated alarm parameters that can be placed on four different thresholds and configurable on each of 250 frequency points within the defined return spectrum.
Data captured is stored up to a full month and can be reviewed instantaneously at anytime.With the addition of the optional PathTrak WebView, performance history up to a year can be reviewed in numerous graphical formats.
The 250 frequency points can be individually programmed for frequency and threshold levels. Each threshold level may have an alarm assigned to it.
There are multiple trigger criteria that are configured to define what activates the alarm. Alarms may be set to trigger off of several different types of changes on the return RF path such as a sustained increase in noise floor level, absence or presence of a carrier level and common path distortion. Logical combinations may be defined to minimize false alarms.
