Abstract: A PoE powered device and method of operation are provided. The device includes a first port unit configured to negotiate receipt of a level of PoE power from a power sourcing equipment. The power is received on a first pair of taps on a first communication port. A detection unit is configured to detect a presence of a first optional circuit load and to detect a presence of a second optional power load. A control circuit is configured to establish connectivity between a second pair of taps on the first communication port and a second powered device port unit in response to the detection unit detecting the first optional load, and further configured to establish connectivity between the second pair of taps and a third pair of taps on a pass-through communication port in response to the detection unit failing to detect the first load and detecting the second load.

Abstract: Certain aspects involve a wideband remote unit. The wideband remote unit can include one or more antennas and an analog-to-digital converter (“ADC”). The antenna can receive wideband signals. The wideband signals can include an uplink RF signal and a leaked downlink RF signal. The uplink RF signal can have an uplink signal power at or near a noise level. The leaked downlink RF signal can have a downlink signal power greater than the uplink signal power. The ADC can convert the received wideband signals to digital RF signals representing the uplink signal and the downlink signal. The wideband remote unit can transmit the digital RF signals to a unit of a DAS that is in communication with a base station.

Abstract: Certain features relate to configuring a distributed antenna system (“DAS”) to interface with and manage components of facility control and monitoring systems while providing wireless communications in a cellular or public safety network. A communications module is configured for receiving facility control signals from facility control and monitoring centers and associated nodes and sensors. A signal processing module is configured to convert the facility control signals a format transportable in the DAS. The signal processing module is also configured to multiplex the facility control signals with mobile voice and data signals being transported in the DAS. The DAS configured to manage components of facility control and monitoring systems can route facility control signals to appropriate facility control centers or the nodes and sensors associated with the facility control centers.

Abstract: An endpoint element of a distributed antenna system includes processing circuitry configured for processing a plurality of digital signals for conditioning the signals and compression circuitry configured for compressing at least one of the digital signals according to a compression scheme to yield at least one compressed digital signal and compression settings. The digital signals are combined into a single digital stream and combined and time division multiplexed onto a serial data link with the compression settings. The digital signals are also transmitted with compression settings to another endpoint element over the serial data link.

Abstract: A system includes: a unit configured to communicate a modulated signal via a signal interface; and at least one additional unit configured to receive the modulated signal from the unit. The at least one additional unit includes circuitry configured to remove jitter from a recovered clock signal to generate a jitter reduced clock signal that tracks long-term drift in the modulated signal, wherein the at least one additional unit is configured to generate the recovered clock signal from the modulated signal.

Abstract: Certain aspects involve power management subsystems for a distributed antenna system (“DAS”) or other telecommunication system. The power management subsystem can include a measurement module and an optimization module. The measurement module can monitor a utilization metric for a remote unit in the DAS or other telecommunication system. The power optimization module can determine whether the remote unit is underutilized based on the monitored utilization metric. The power optimization module can configure the remote unit for a low-power operation in response to determining that the remote unit is underutilized.

Abstract: Certain features relate to improving the link-fault tolerance in a distributed antenna system (DAS) by utilizing a series of synchronous communication frames. A receiving remote unit or a head-end unit in the DAS can predict the start of incoming communication frames based on frame information extracted from previously received communication frames. For example, a remote unit can be configured to receive one or more communication frames, each of the one or more communication frames including a start-of-frame field. After a period of time corresponding to the frame repetition rate, the remote unit can search for an additional start-of-frame field, indicating the receipt of the next communication frame. The remote unit can extract the payload data from the next communication frame based on the predicted value for the additional start-of-frame field.

Abstract: Method and apparatus for generating a jitter reduced clock signal from signal transmitted over a communication medium includes receiving, with high speed data interface circuitry, a modulated signal that includes a binary encoded data stream. A recovered clock signal is generated from the modulated signal and tracks the long-term drift in the modulated signal. A jitter reduced clock signal is generated by filtering the recovered clock signal with a filtering circuit having a bandwidth sufficient to remove jitter while allowing the jitter reduced clock signal to track the drift in the modulated signal.

Abstract: A telecommunications system is provided that includes a unit for communicating channelized digital baseband signals with remotely located units. The channelized digital baseband signals include call information for wireless communication. The unit includes a channelizer section and a transport section. The channelizer section can extract, per channel, the channelized digital baseband signals using channel filters and digital down-converters. The transport section can format the channelized digital baseband signals for transport together using a transport schedule unit for packetizing and packet scheduling the channelized digital baseband signals. A signal processing subsystem can control a gain of uplink digital baseband signals, independently, that are received from the remotely located units prior to summing the uplink digital baseband signals.
