It has been hypothesized that the threat to the internet, infrastructure and services posed by squirrels may exceed that posed by cyber-attacks. [1] Although many commentators have highlighted humorous aspects of the concern, squirrels have proven consistently able to cripple power grids in many countries, [ 2 ] and the danger posed to the ...
Data Carrier Detect (DCD) or Carrier Detect (CD) is a control signal present inside an RS-232 serial communications cable that goes between a computer and another device, such as a modem. This signal is a simple "high/low" status bit that is sent from a data communications equipment (DCE) to a data terminal equipment (DTE), i.e., from the modem ...
Return loss is a measure of how well devices or lines are matched. A match is good if the return loss is high. A high return loss is desirable and results in a lower insertion loss. From a certain perspective 'Return Loss' is a misnomer. The usual function of a transmission line is to convey power from a source to a load with minimal loss.
Finnish investigators late last month seized a tanker carrying Russian oil and said they suspected the vessel had damaged the Finnish-Estonian Estlink 2 power line and several internet cables by ...
Power outages are categorized into three different phenomena, relating to the duration and effect of the outage: A transient fault is a loss of power typically caused by a fault on a power line, e.g. a short circuit or flashover. Power is automatically restored once the fault is cleared. A brownout is a drop in voltage in an electrical power ...

The phones are only partially compatible with newer or older versions of the hub, able to make and receive calls, but with the loss of features including call waiting, call transfer, internal calls, phonebook, call lists and Hi-def sound.
Standby power, also called vampire power [1], vampire draw, phantom load, ghost load, or leaking electricity, refers to how electronic and electrical appliances consume electric power. At the same time, they are switched off (but are designed to draw some power) or in standby mode. It only occurs because some devices claim to be "switched off ...
Some taps get some of their power (i.e., for the pass-through) or all of their power (i.e., for both pass-through and monitor) from the network itself. These can be referred to as having inline power. Some taps can also reproduce low-level network errors, such as short frames, bad CRC or corrupted data. Basic functionality of an optical network tap
