Techniques for supporting optical and electrical protocols, such as on the ports of a line card in a network device, are provided. A port on a line card supports optical and electrical connections. The PHY monitors a signal to determine if the transmission connection at the port has changed, such as from optical to electrical, or vice versa. If there has been a change, the PHY is directed to reset a port to correspond to the appropriate transmission connection. By resetting the port, the PHY changes the protocol that is utilized with the signals (e.g., NRZI or 3-Level MLT3).

Radio frequency signal boosters are provided herein. In certain embodiments, a signal booster system includes a signal booster that is proximately located to an outdoor base station antenna. Implementing the signal booster system in this manner can provide a number of advantages relative to a configuration in which the signal booster is far from a base station antenna. For example, a long cable connected from an indoor signal booster to an outdoor base station antenna can be several meters long, resulting in significant cable loss that degrades transmit power and/or receiver sensitivity.

A sensor system is provided that is incorporated into the passenger cabin of a vehicle and which is configured to detect children and/or pets left unattended and who are therefore at risk of serious injury or death due to heat stroke. The system is designed to transmit a variety of alerts over time after an unattended child or pet is detected, the escalating nature of the alerts intended to insure a rapid response. After the system has operated long enough to insure that no child or pet has been left behind, the sensor system is automatically placed into a standby mode. In standby mode the sensor system may either be turned completely off in order to minimize off-line power consumption or it may be incorporated into an on-board security system.

A vertical column assembly including an intermediate distribution frame enclosure with an internal structure. The vertical column assembly also includes side panels, door assemblies, and a top cover assembly. The internal structure is hidden by the side panels, the door assemblies, and the top cover assembly. The vertical column assembly encases the network equipment installed within the internal structure.

Certain embodiments of the present invention relate to an in-house relay device capable of 5G wireless communication and support equipment for supporting same, the support equipment comprising: a vertical rod installed in a z-axis direction from the bottom surface; a support member disposed at one end of the vertical rod to be coupled to the vertical rod, and supporting the in-house relay device; and a fixing member coupled to the support member and fixing the support member in a direction of a permeable outer wall, wherein the support member may comprise a rotating plate for adjusting a direction of the in-house relay device.

Apparatus and methods for signal boosters for vehicles are provided. In certain embodiments, a vehicle signal booster system includes an interior unit including a mobile station antenna that receives an RF uplink signal and transmits a boosted RF downlink signal. The vehicle signal booster system further includes a top unit including a base station antenna that receives an RF downlink signal and transmits a boosted RF uplink signal. The vehicle signal booster system further includes booster circuitry that generates the boosted RF downlink signal based on amplifying one or more downlink channels of the RF downlink signal, and that generates the boosted RF uplink signal based on amplifying one or more uplink channels of the RF uplink signal. The booster circuitry is implemented in the top unit or in the top unit and the interior unit.
