  • Patent number: 6633566
    Abstract: A method, apparatus, and computer program product of interfacing a time-domain multiplexed (TDM) link with a cell-switched network. The TDM link supports one or more active channels and one or more idle channels and supplies TDM frames with a sample of each channel in a dedicated timeslot. The TDM link is terminated at a first network node. One or more idle timeslots are removed from each TDM frame to create a compressed TDM frame, where each idle timeslot carries a sample of an idle channel. One or more compressed TDM frames are loaded in a cell that is sent over the cell-switched network to a second network node. The compressed TDM frames are unloaded from the cell. Idle timeslots are inserted in the compressed TDM frames to restore the compressed TDM frames to complete TDM frames. The bandwidth of the cell switched network is efficiently utilized because idle channel samples are not carried over the cell-switched network.

  • Publication number: 20030189916
    Abstract: A control channel supporting traffic control in epochs is divided into two control subchannels each being less than or equal to about a half epoch in duration and occurring serially in time. Slot allocation data may be transmitted and received independently over the subchannels. One subchannel may be used for transmitting forward slot allocation data and the other subchannel may be used for transmitting reverse slot allocation data. The channel split into two subchannels may be a paging channel. The forward and reverse slot allocation data may be transmitted between a base station processor and field unit. Forward and reverse traffic data may be staggered by at least about half an epoch. Transmission of traffic data happens within about two epochs after the assignments.

  • Publication number: 20030190040
    Abstract: Apparatus and accompanying methods for use in a long-haul echo control device to automatically measure sufficient changes in path length and compensate a long-haul echo canceller for resulting variations in echo occurring over those paths. Specifically, the inventive apparatus measures a round-trip path delay interval of, e.g., a predefined signalling tone(s) sent between international switching centers during the course of establishing an outbound call connection over that path. Once this delay interval is measured, the apparatus commensurately sets echo delay of a corresponding long-haul echo canceller to accommodate this path delay. For a multi-channel facility (e.g., T1 or E1), path delay is separately measured for each channel on that facility. Should the measured path delay sufficiently change for any one such channel, then the apparatus changes the echo delay to the same amount for the corresponding echo canceller associated with each and every channel on that facility.

  • Patent number: 6630910
    Abstract: A wireless communication device coupled to a wave antenna that provides greater increased durability and impedance matching. The wave antenna is a conductor that is bent in alternating sections to form peaks and valleys. The wireless communication device is coupled to the wave antenna to provide wireless communication with other communication devices, such as an interrogation reader. The wireless communication device and wave antenna may be placed on objects, goods, or other articles of manufacture that are subject to forces such that the wave antenna may be stretched or compressed during the manufacture and/or use of such object, good or article of manufacture. The wave antenna, because of its bent structure, is capable of stretching and compressing more easily than other structures, reducing the wireless communication device's susceptibility to damage or breaks that might render the wireless communication device coupled to the wave antenna unable to properly communicate information wirelessly.
