Abstract: Systems and related accessing methods for remote unit assemblies for distributed communications systems are provided. A support member (e.g., a support plate) is arranged to be mounted in a drop ceiling grid, and a pivotally mounted pivot arm arranged above the support plate is configured to receive at least one electronic component. The pivot arm allows the electronic component to pivot downwardly from a ceiling structure for easier access. A slow release mechanism is configured to reduce a rate of pivotal motion of the pivot arm. A retention mechanism selectively retains the electronic component in a substantially horizontal position proximate to the support plate. A vented antenna cover below the support plate is pivotally mounted to the electronic component with at least one pivotal link, and may include an integrated antenna.

Abstract: Safety power disconnection for remote power distribution in power distribution systems is disclosed. The power distribution system includes one or more power distribution circuits each configured to remotely distribute power from a power source over current carrying power conductors to remote units to provide power for remote unit operations. A remote unit is configured to decouple power from the power conductors thereby disconnecting the load of the remote unit from the power distribution system. A current measurement circuit in the power distribution system measures current flowing on the power conductors and provides a current measurement to the controller circuit. The controller circuit is configured to disconnect the power source from the power conductors for safety reasons in response to detecting a current from the power source in excess of a threshold current level indicating a load.

Analog RF communications signals received from analog RF signal sources are distributed in the analog DAS without being digitized.

Hence, a digital signal interface in head-end equipment (HEE) is configured to convert downlink digital communications signals to downlink analog RF communications signals for distribution to a plurality of remote units. The digital signal interface is also configured to convert uplink analog RF communications signals to uplink digital communications signals for distribution to the digital signal source(s).

The intermediate power supply unit also includes a power converter circuit configured to convert voltage on higher voltage inputs to a lower voltage applied to one or more lower voltage outputs. The power converter circuit is also configured to distribute power from the one or more lower voltage outputs over a power conductor coupled to an assigned remote device.

Abstract: Distribution of management services in distributed antenna systems having a central unit and remote units configured to time-division multiplex (TDM) downlink and/or uplink management signals into time slots to form a TDM management frame signal. In this manner, collision will not occur between multiple management signals communicated over a common communications medium at the same time in the distributed antenna system. Collision detection and management mechanism can add design complexity, cost by requiring additional components, and require additional area on electronic boards. The TDM management frame signal may also be modulated at a carrier frequency before being combined with RF communications signals so that the combined signals are within a linear range of shared certain communications components to reduce cost and area.

Abstract: Embodiments disclosed herein include combining power from isolated power paths for powering remote units in distributed antenna systems (DASs). In one example, a remote unit(s) is configured to include multiple input power ports for receiving power from multiple power paths. The received power from each input power port is combined to provide a combined output power for powering the remote unit. Thus, a remote unit can be powered by the combined output power. To avoid differences in received power on the multiple input power ports causing a power supply to supply higher power than designed or regulated, the input power ports in the remote unit are electrically isolated from each other. Further, the received power on the multiple power inputs ports can be controlled to be proportionally provided to the combined output power according to the maximum power supplying capabilities of the respective power supplies.

Abstract: Connectivity between components in a system is monitored by applying a low voltage at one end of an RF cable, interpreted as a “0” logical state, and determining whether a similar voltage appears at the other end of the cable. If the cable is connected properly, the DC voltage applied at one end will appear at the other end and a proper indication is generated. If the expected voltage level does not appear at the other side, it means that RF connection was not correctly established and an alert is generated. Test systems for testing connectivity may include a first component comprising at least one port, at least one capacitor, and at least one resistor for providing high impedance. A controller provides a first logic state to the at least one port, scans multiple input ports of the system, and records a link corresponding to the applied first logic state.
