First Claim
1. A method performed by data processing apparatus, the method comprising:
- for each of a plurality of communications channels of a power line communications system implemented in a power distribution system;
monitoring, by a data processing apparatus, signal characteristic values for signals transmitted over the channel;
determining, by the data processing apparatus and based on the monitored signal characteristic values, that a signal level value for the channel is less than a threshold signal level value for the channel;
in response to determining that the signal level value for the channel is less than the threshold signal level value for the channel;
computing, by the data processing apparatus, a signal to noise ratio for the communications channel;
determining, by the data processing apparatus, that the signal to noise ratio for the channel exceeds a threshold value; and
in response to determining that the signal to noise ratio for the communications channel exceeds the threshold value, storing, by the data processing apparatus, data received over the communications channel as valid data.

Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for identifying network events. In one aspect, a method includes monitoring signal characteristic values for signals transmitted over a communications channel of a power line communications system and determining that a signal level value for the channel is less than a threshold signal level value for the channel. In response to determining that the signal level value for the channel is less than the threshold signal level value for the channel, computing a signal to noise ratio for the communications channel and determining that the signal to noise ratio for the channel exceeds a threshold value. In response to determining that the signal to noise ratio for the communications channel exceeds the threshold value, storing data received over the communications channel as valid data.

8. A computer-implemented method, comprising:
for each of a plurality of communications channels of a power line communications system implemented in a power distribution system; monitoring, by a data processing apparatus, signal characteristic values for signals transmitted over the channel; determining, by the data processing apparatus and based on the monitored signal characteristic values, that a signal level value for the channel is less than a threshold signal level value for the channel; computing, by the data processing apparatus, a signal to noise ratio for the communications channel; determining, by the data processing apparatus, whether the signal to noise ratio for the channel is less than a threshold value; in response to determining that the signal to noise ratio for the communications channel is less than the threshold value, preventing, by the data processing apparatus, storage of data received over the communications channel as valid data; and in response to determining that the signal to noise ratio for the communications channel is not less than the threshold value, storing, by the data processing apparatus, data received over the communications channel as valid data.
