Detection of damaged switched diplex filter
Methods, systems and computer readable media described herein may facilitate a detection of a damaged switched diplex filter. A CPE device may be equipped with one or more switches and one or more A/D converters. The one or more A/D converters may be utilized to monitor voltage at the one or more switches. In response to a detection of a rise in voltage above a threshold at a switch, upstream transmissions may be disabled at the CPE device.
1. A method comprising:
reading a voltage at a battery backup input;
determining that the voltage is greater than a threshold voltage, wherein the battery backup input is associated with a first switch and a second switch, wherein the voltage read at the battery backup input is associated with either the first switch or the second switch, wherein the first switch is associated with a first threshold voltage, and wherein the second switch is associated with a second threshold voltage;
outputting an alert indicating a voltage rise; and
disabling upstream transmissions.
2. The method of claim 1 , wherein the first threshold voltage and the second threshold voltage comprise different values.
3. An apparatus comprising:
a battery backup input; and
one or more modules that:
read a voltage at the battery backup input;
determines that the voltage is greater than a threshold voltage;
outputs an alert indicating a voltage rise; and
disables upstream transmissions; and
a first switch and a second switch, wherein the voltage read at the battery backup input is associated with either the first switch or the second switch, wherein the first switch is associated with a first threshold voltage, and wherein the second switch is associated with a second threshold voltage.
4. The apparatus of claim 3 , wherein the first threshold voltage and the second threshold voltage comprise different values.
5. One or more non-transitory computer readable media operable to execute on one or more processors, the computer readable being operable to cause the one or more processors to perform the operations comprising:
reading a voltage at a battery backup input;
determining that the voltage is greater than a threshold voltage, wherein the battery backup input is associated with a first switch and a second switch, wherein the voltage read at the battery backup input is associated with either the first switch or the second switch, wherein the first switch is associated with a first threshold voltage, and wherein the second switch is associated with a second threshold voltage;
outputting an alert indicating a voltage rise; and
disabling upstream transmissions.
6. The one or more non-transitory computer readable media of claim 5 , wherein the first threshold voltage and the second threshold voltage comprise different values.
