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:
A subscriber station for the wireless connection of user telecommunications equipment to a remote central station of a wireless telecommunications system includes a transmitter/receiver for wireless communication with the central station, at least one telephone line for connection to subscriber telecommunications equipment and a communications controller connected between the transmitter/receiver and the telephone line for processing signals for transmission and/or received signals. The subscriber station is configurable in response to wireless programming signals representative of control code down-loaded from the central station. By enabling the down-loading of software for programming the subscriber station, the flexibility and convenience of configuring the subscriber station, both initially and subsequently, is greatly enhanced.
摘要:
A grooming device (18) includes an inbound crosspoint switch (30) that combines proprietary STS-1 signals from any of a plurality of optical terminators (16) into a grouped set of output signals for transmission to a broadband matrix subsystem through dedicated matrix interfaces (20). The inbound crosspoint switch (30) includes a crosspoint matrix (72) that receives each of the plurality of input signal lines at each output signal port and selects which input signal line is connected to which output signal port as determined by a microprocessor controller (78). Each output signal port has a register (90) for storing information as to which input signal line is to be connected to that port. A decoder (92) generates a control signal from the information stored in the register (90) to drive a multiplexer (94) for selection of the appropriate input signal line.

A redundancy switch (44) provides interfacing of network signals to spare network processors (46) in the event of a failure of a main network processor (42). A redundancy switch (44) allows for monitoring and diagnostic operations to be performed on network electrical signals without interrupting traffic flow on inbound and outbound paths. A redundancy switch (44) performs a loopback diagnostic by routing signals from transmitter portions of the spare network processors (46) to selected receiver portions. The redundancy switch (44) includes a receiver interface unit (90) and a transmitter interface unit (92) capable of routing inbound and outbound customer signals to and from the spare processors (46) for monitoring, diagnostic, and sparing purposes.

A distributed personal communication service system (30) includes a plurality of delivery units (14) under the control and supervision of a service unit (12). Each delivery unit (14) receives wireless call information from a plurality of radio transceivers (32) as transmitted by wireless hand held personal telephone units (34) within a zone of coverage (36) of the radio transceivers (32). Each delivery unit (14) provides the switching function and network interfaces to transmit the call information to other delivery units (14) along a fiber optic ring (16) or other wireless or wire line networks. Each delivery unit (14) also outputs call information to the radio transceiver (32) for transmission to and receipt by the wireless personal telephone unit (34). Each delivery unit (14) supports wire line telephony network interfaces through interconnection to central offices (38), local exchange carriers, and interexchange carrier carriers. The service unit (12) controls and directs each delivery unit (14) in the switching of call information from origination to destination.
摘要:
A method and apparatus are provided for monitoring power loss in a telecommunications system. Power is received from a permanent power source. A loss of power from the permanent power source is detected. Responsive to the detection of loss of power, a message indicative of a power failure is transmitted at least once on an optical fiber, the message transmission being powered by a temporary power source.
摘要:
A distributed object messaging system and method (10) are provided for a plurality of nodes (15-21, 25-32) distributed in multiple physically separate sites (12, 13). There are a plurality of processes (40-44) executing in each node. The processes register a plurality of objects in each node. The objects include client objects and server objects. The server objects may be registered for global service for service availability to client objects in a local node, local site and/or site global service for service availability for client object in remote sites. A server object database (46) is used in each node to store a server object description for each server object registered in the node and objects registered in remote nodes that are registered for global or site global service. A client-server interface (50) is accessible by client objects and receives requests for services therefrom. The client-server interface accesses the server object database (46) for at least one destination server object capable of performing the client object's requested service, and forwards the service request to the destination server objects at a local site or a remote site.
摘要:
A control system for a wireless telecommunications system, the control system comprising: a server maintaining an object based control structure for controlling the telecommunications system; and an interface to at least one control terminal of the telecommunications system and to at least one client station; wherein the server is responsive to signals from the at least one control terminal and/or to instructions from the at least one client station to generate an operation, the operation being applied to at least one object to effect a change in the at least one object, thereby to control the telecommunications system.
