摘要： A small form-factor transceiver module performs protocol translation, in addition to the conventional electrical and/or optical transmission media conversion. Such protocol conversion may enable transport of traffic from limited-range primary networks over long-range secondary networks, such as extension of Ethernet networks over low-rate TDM links. Additionally, such protocol conversion may enable interworking between different networks of differing technologies, such as transport of ATM traffic over Ethernet networks. The transceiver module may be a Small Form Factor transceiver (SFF), Small Form Factor pluggable module (SFP), Gigabit Interface Converter (GBIC) or any similar small form-factor module consisting of a housing, internal electronic circuitry and optionally optical components, and associated electrical or optical connectors. The transceiver module performs protocol translation by means of an integral protocol translation unit that performs standards-based or proprietary conversion between network protocols.

摘要： A system and method for extending the distance that xDSL services are able to be provided to subscribers (310a-310e). A DSLAM (300) located at a Central Office (301) is connected to a general-purpose network, such as the Internet. The DSLAM (300) is additionally connected to a first fiber optic transceiver. The first fiber optic transceiver (302) is connected via a fiber optic link (316)to a second fiber optic transceiver (306) located proximate to the subscribers' premises, preferably in a street cabinet (305). Each subscriber premise's equipment (310a-310e) is connected to the broadband transceiver (306) via subscriber lines (308a-308e). Electrical signals to be transmitted between the Central Office (301) and the subscribers' premises are utilized to form a frequency division multiplexed signal. The frequency division multiplexed signal is used to modulate a light subcarrier for transmission across the fiber optic link (316). At the respective receiving transceiver, the frequency division multiplexed signal is reconverted to the electrical signals, which are then applied to the subscriber premises equipment or DSLAM (300) depending upon the direction of communication.

摘要： A method and system in which a Digital Subscriber Line Access Multiplexer (DSLAM) that is part of a DSL (Digital Subscriber Line) system is able to provide synchronous services to end user equipment connected to the DSLAM via a DSL link and Customer Premises Equipment (CPE). A sniffer device having direct or indirect access to a Primary Reference Clock (PRC) of the DSL system calculates the phase difference between the PRC and the DSLAM's Local Timing Reference (LTR). The phase difference is sent to the CPEs requiring accurate reference clock frequency. The CPEs are able to derive the PRC from the phase difference information transmitted by the sniffer device thus enabling synchronous end user equipment operation.

摘要： A method for measuring one-way delays in a communications network, the method comprising: maintaining a virtual clock state comprising information for converting times measured with respect to remote clocks into times as would be measured with respect to a local reference clock; registering, for each packet of the plurality of packets in a communications session between the first and second nodes, a timeset comprising transmission and reception times at the first and second nodes; converting, responsive to the virtual clock, times in the timeset measured with respect to the first node clock or the second node clock, into times as would be measured with respect to the reference clock; calculating, for each packet of the series of packets, a forward one-way delay (FOWD) from the first node to the second node and a reverse one-way delay (ROWD) from the second node to the first node, responsive to the converted timeset.

摘要： The present disclosure describes systems and methods for escorting small unmanned aircraft (herein drones). An escorting drone approaches the escorted drone and transmits to it an escort signal. In an embodiment, the escort signal is a GNSS signal fashioned to be the same as the GNSS signal that would be received by the escorted drone, other than being slightly stronger in signal strength and having slightly altered component delays. In another embodiment, the escort signal is a radio frequency control channel signal. Escorting may be utilized to guide a drone from a preprogrammed point to a docking zone in a droneport; to guide a drone though an urban canyon or inside a building where GNSS signals are not reliably received; to retrieve a drone with which communications has been lost; or to escort a drone to safety out of a no- flight zone such as around an airport.

摘要： A system and method of compressing audio signals (110, 116, 130, 136, 140, 146) which simultaneously contain speech (110, 116), music (130,136, 140, 146) and possibly other audio in such fashion as to reduce the required bandwidth or storage capacity. Audio (110, 116, 130, 136, 140, 146) is transmitted as simultaneous but separate streams of speech audio (110, 116) and music (or other non-speech) audio (130, 136, 140, 146), as well as other streams such as video (210, 216), text (120, 220), computer graphics (230), etc. By keeping the music (130, 136, 140, 146) separate from the speech (110, 116), each can be maximally compressed. By synchronizing these streams (110,, 116, 130, 136, 140, 146, 210, 216, 220, 230), the desired combination can be recreated at the receiver with the user being unaware of the separation. Instead of analog or digital mixing of the music or other non-speech audio (130, 136, 140, 146) with the speech audio (110, 116) to create a composite audio stream (110, 116, 130, 136, 140, 146), the streams are kept logically separate, and, thus, can be optimally compressed using existing technologies.
