First Claim
1. Non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed, perform a method in a communications network for setting signal-power-received threshold values on one or more nodes in the communications network, the method comprising:
- via a computing device, calculating a transmit-power level for a segment of the communications network based on design specifications for the communications network;
determining a maximum and a minimum signal-power-received threshold for the segment using the transmit-power level;
specifying an alarm condition for performance of the segment based on the maximum and minimum signal-power-received thresholds for the segment;
adjusting a sensitivity of the alarm condition based on the performance of the segment by expanding a range of the maximum and minimum signal-power-received thresholds when actual performance of the communications network is better than expected based on the design specifications or decreasing a range of the signal-power-received thresholds when actual performance of the communications network is poorer than expected based on the design specifications;
via the computing device, setting the signal-power-received thresholds for the segment on one or more nodes in the segment;
detecting a change to one of the plurality of nodes in the segment, now an altered segment;
automatically calculating new signal-power-received thresholds for the altered segment; and
setting the new signal-power-received thresholds on the altered segment.

Abstract
Systems and media for setting signal-power-received threshold values on nodes of a communications network. A segment on a route of a communications network transmission route is identified. A number of spans in the segment and a number of channels transmitted over a segment is determined. Based on design specifications, a signal-power-received threshold value is calculated. The signal-power-received threshold value may be adjusted to accommodate for segment performance. The signal-power-received threshold value is communicated to and set on one or more nodes on the segment.
