Abstract:

Systems and methods for maintaining data stream synchronization are provided. A system comprises one or more radio head interface modules and a call processing software module each adapted to communicate with each other. The call processing software module performs modulation and demodulation of voice and data streams using one or more air interface standards. The call processing software module communicates a forward data stream to a first radio head interface module. The forward data stream comprises a plurality of data samples representing voice and data streams and a plurality of fixed synchronization words. When the first radio head interface module does not observe the receipt of a first fixed synchronization word of the plurality of fixed synchronization words word from the call processing software module when expected, the first radio head interface module concludes that it has lost synchronization with the call processing software module.

International Classification:

G06F 13/36

US Classification:

710116, 710106, 713502, 370462

Abstract:

A method for controlling bi-directional data transfers in an electronic circuit is provided. The method involves when a first of at least two data signals is activated as an originating data signal prior to a second of the at least two data signals: allowing only a device associated with the first of the at least two data signals to be a signal source, and causing a device associated with the second of the at least two data signals to enter a receive state as a signal sink. The method further involves passing at least one bit of data from the signal source to the signal sink.

US Classification:

717168

Abstract:

A method of upgrading the system capability of a communications network is provided. The method involves initiating a transfer of at least one set of upgraded system capability software machine-coded instructions to a host card, instructing the host card to begin an upgrade process, determining whether at least one set of system capability software machine-coded instructions on the host card is valid, and completing the transfer of at least one valid set of system capability software machine-coded instructions to the host card, wherein the system capability is upgraded without affecting operation of the network.

Abstract:

A method for programming the delay for a node in a communication system is disclosed. The node receives a selected delay value and a signal path delay value indicating a delay for signals communicated to the node. The signal path delay comprises an aggregation of transport delays calculated by each node for segments of the communication system between the node and a host node. The method further calculates an additional delay necessary to meet the selected delay value.

Abstract:

Clock Priority Chain Level Systems and Methods are provided. In one embodiment, a method for determining clock priority for a multihost unit distributed antenna system is provided. The method comprises identifying which port of a plurality of ports is receiving a reference clock signal having a highest priority Network Chain Level (NCL) value, wherein the highest priority NCL value indicates a master clock priority level (MCPL) of a host unit providing a Master Clock and a chain level value indicating a chain depth; selecting a system clock reference port from the plurality of ports based on the highest priority NCL value; locking a local clock to a reference clock signal received on the selected system clock reference port; calculating an incremented NCL value based on the highest priority NCL value; and transmitting the incremented NCL value over the plurality of ports.
