摘要： The present invention provides a transmission controller and method for processing data items to be transmitted over a wireless link connecting a central terminal and a subscriber terminal of a wireless telecommunications system, a single frequency channel being employed for transmitting data items pertaining to a plurality of wireless links. The transmission controller comprises an orthogonal code generator for providing an orthogonal code from a set of `m` orthogonal codes used to create `m` orthogonal channels within the single frequency channel, and a first encoder for combining a data item to be transmitted on the single frequency channel with said orthogonal code from the orthogonal code generator, the orthogonal code determining the orthogonal channel over which the data item is transmitted, whereby data items pertaining to different wireless links may be transmitted simultaneously within different orthogonal channels of said single frequency channel. Further, the transmission controller comprises a TDM encoder arranged to apply time division multiplexing (TDM) techniques to the data item in order to insert the data item within a time slot of the orthogonal channel, whereby a plurality of data items relating to different wireless links may be transmitted within the same orthogonal channel during a predetermined frame period. The invention also provides a reception controller and method for processing data items received over a wireless link.

摘要： A wireless telecommunications system (1) includes a central terminal (10) for transmitting and receiving radio frequency signals to and from a subscriber terminal (20). A downlink communication path is established from a transmitter (200) of the central terminal (10) to a receiver (202) of the subscriber terminal (20). A downlink signal (212) is transmitted from the transmitter (200) to the receiver (202) during setup and operation of the wireless telecommunications system (1). The receiver (202) of the subscriber terminal (20) compares a code and phase of a master code sequence in the downlink signal (212) to a code and phase of a slave code sequence of the receiver (202). The receiver (202) adjusts the phase of the slave code sequence until a match is obtained with the master code sequence. Matching of the slave code sequence to the master code sequence facilitates establishment of the downlink communication path.

摘要： A subscriber station monitor system is provided for a subscriber station of a wireless telecommunications system. The subscriber station includes a transmitter/receiver for wireless communication with a central station and a communications controller for processing signals for transmission and/or received signals, a supply unit for connection to one or more telephone lines for user telecommunications equipment and a link connecting the communications controller to the supply unit, control data being passed in accordance with an internal protocol between the communications controller and the supply unit via the link. The station monitor system comprises a display and at least one user input device, a connector to the link and a protocol interpreter for extracting control data to be displayed on the display for monitoring the operation of the subscriber station and/or for inserting input control data to the link for configuring the subscriber station. By providing a separate monitor system for connection to the subscriber station in the link between the transmitter/receiver and the supply unit, monitoring and control of selected subscriber terminal functions is readily possible.

摘要： Message packets for passing control information between a central telecommunications station and a controller for one or more telecommunications stations include: a packet header including a packet start pattern and a message size identifier for individually setting a message size for respective packets; a variable number of message records, each having a size relating to the message size selected for the packet; and a packet terminator including a unique packet end pattern invalid as an initial bit sequence for a message record. The tracking of transmissions is facilitated by the use of cyclical sequence numbers and an arrangement whereby up to a predetermined number of messages may be sent without an acknowledgment.

摘要： The present invention provides a housing for holding a rack of equipment(210), the housing comprising a main enclosure portion (200) for retaining the rack (210), and the main enclosure portion (200) comprising a conductive wall (310). A wiring portion (205) distinct from said main enclosure portion (200) is also provided for receiving one or more wires (220) to be routed to said rack (210), the wires (220) being routed through said conductive wall (310) to said rack (210), and an outer portion of the wires (200) being earthed against said conductive wall (310), thereby inhibiting the transmission of noise along said wires (220) to said rack (210).Hence, by ensuring that the main enclosure portion (200) has at least one conductive wall (310), and that the wires (220) are routed from the wiring portion (205) to the main enclosure portion (200) via that conductive wall (310), and earthed as they pass through the conductive wall (310), a simple mechanism is provided for effectively inhibiting the transmission of noise along the wires (200) to the rack (210).

摘要： A subscriber station of a wireless telecommunications system includes a transmitter/receiver (24) for wireless communication with a central station and for processing signals for transmission and/or received signals. The transmitter/receiver (24) is connected via a link (408) to a supply unit (30) for connection to one or more telephone lines for user telecommunications equipment. The link (408) carries telephone call data for one or more telephone lines and subscriber station control data in accordance with an internal protocol. The internal protocol control data comprises operational status parameters of the subscriber station. The provision of internal protocol control data including operation status parameters on a link between the transmitter/receiver and the supply unit thus provides a point of access for monitoring the operational status of the subscriber station.

摘要： The present invention provides a bandwidth management system, a subscriber terminal, and a method for managing calls between a central terminal and a subscriber terminal of a wireless telecommunications system, a number of items of telecommunications equipment being connectable to the subscriber terminal. The subscriber terminal is arranged to pass call data between said items of telecommunications equipment and the central terminal via a wireless link, the wireless link being provided on a frequency channel with a predetermined maximum call data bandwidth for the transmission of said call data. The bandwidth management system comprises a bandwidth manager for maintaining in a storage information about allocation of the predetermined maximum call data bandwidth amongst calls currently being handled on the frequency channel. Further, a bandwidth allocator is provided that, responsive to a request to establish a call, is arranged to allocate, with reference to the information in said storage, a call data bandwidth for the call. The bandwidth manager then uses the call data bandwidth allocated by the bandwidth allocator to update the information in the storage. In preferred embodiments, the type of call to be established is determined, and the bandwidth allocator uses this call type information when allocating the call data bandwidth for the call. Compression may then be applied to the call data dependent on the bandwidth allocated.
