摘要： 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.

摘要： 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.

摘要： An intermediate power supply unit for distributing lower voltage power to remote devices is disclosed. The intermediate power supply unit includes a higher voltage power input configured to receive power distributed by a power source and a power coupling circuit configured to couple the higher voltage power input to a plurality of power coupling outputs. If it is determined that a wire coupling the power source to the higher voltage power input is touched, the higher voltage power input is decoupled from the power coupling outputs. 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.

摘要： Embodiments disclosed in the detailed description include analog distributed antenna system (DAS) supporting distribution of digital communications signals interfaced from a digital signal source and analog radio frequency (RF) communications signals. Analog RF communications signals received from analog RF signal sources are distributed in the analog DAS without being digitized. The analog DAS is also configured to interface with digital signal sources and compatibly distribute digital communications signals. 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). By providing the digital signal interface in the HEE, the analog DAS can be configured to distribute digital communications signals to analog DAS components.

摘要： 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.

摘要： Power distribution modules in distributed antenna systems include fan monitoring circuits for indicating an alarm condition to head-end equipment. The alarm condition can be used by system operator/owners that a fan is drawing excessive power, thereby detracting from system performance, or indicating that the fan may fail. The alarm condition signal can be returned to the head-end equipment via an uplink communication path between a remote unit powered by the module and the head-end equipment.
