The plurality of services are activated over the at least one communication link. Transmission for the prevented service is prevented based on at least one characteristic of the at least one communication link over which the prevented service would be provided.

Abstract: A method for providing spectral containment over telecommunications service lines is provided. The method includes selecting a filter having spectral characteristics corresponding to a predetermined passband. The method also includes connecting the filter in series to at least one loop used to provide at least one telecommunications service to a customer. The method further includes activating service over the at least one loop. The filter attenuates signals transmitted on frequencies outside of the predetermined passband over the at least one loop.

Abstract: A filter passing only desired frequencies is selected according to a desired level of service for copper lines. At a point of access between a loop plant and Central Office, the filter is interposed in series over a telephone service line to provide spectral containment by restricting the frequencies of transmission passing along the line. The filter is preferably mounted within a 5-pin module used in a protector block at the Central Office or remote terminal facility, interfaces with a 5-pin module, or is placed upstream or downstream of a protector block such that it does not interfere with the operation thereof. Service is activated, and the spectral containment apparatus prevents the transmission of unexpected or unintended services over the line.

Abstract: A method of facing a substrate comprises the steps of first welding a body of a hard facing material to the substrate and then filling a space around the body with a molten metal. The method can be used in the hard facing of metal components with, for example, hard facing materials such as tungsten carbide. The substrate can comprise a metal surface, which can, for example, be the surface of any suitable component, tool, or implement subject to wear in use. The method is particularly suitable for hard facing the wear surfaces of components for use in drill strings in down-hole drilling technology, for example, drill stabilizers.

Abstract: A receiver for transmitted signals which represent digital symbol values includes a low-pass filter to minimize transmission noise by reducing the receiver bandwidth. However, this creates pulse distortion which can cause intersymbol interference when the filtered signal is supplied to a symbol detector. Such interference is minimized by the inclusion of a feedback loop between the output of the symbol detector and the input to the filter, in which a detected symbol is multiplied by correction factor and supplied to a subtractor where it is subtracted from the signal to be filtered. The result of the subtraction is supplied to the filter. The noise reduction filter is thus also used for matching the intersymbol distortion characteristic of a filtered detected symbol to the intersymbol distortion characteristic of a filtered received signal pulse.

Abstract: A compiler is provided to a network element management subsystem for compiling rules and behaviors of device types into nested meta data structures of model databases. The rules and behaviors of the device types are specified via definitions describing controls of the device types, and features assignable to the device types. In one embodiment, the compiler is a two phase compiler comprising a parsing and list building phase and a database building phase. The device type model databases are loaded into memory to allow fast access and traversal. Each of the model databases comprises a plurality of nested meta data structures. Data are conditionally retrieved by selectively traversing the model databases using navigation sequences. An array of evaluation functions is further provided to evaluate predicates embedded in the nested meta data structures in view of operational data. During operation, user and system actions are interpreted through device emulation accessing the appropriate model databases.

Abstract: For avoiding error propagation as a result of decision feedback equalization, the data to be transmitted are coded with a coder 2 which has a transfer function substantially inverse to the transfer function of the channel 4. Consequently, instantaneous decisions about the received symbol may be made at the receiver 6 without intersymbol interference causing a disturbance. If the channel transfer function differs from the transfer function of the precoder 2, intersymbol interference will again occur, so that the symbol error rate will increase. In order to restrict this increase of the symbol error rate as much as possible, the receiver comprises a cascaded circuit of an adaptive filter 18 which has an inverse transfer function to that of the channel and a decoder 21 which has an inverse transfer function to that of the precoder 2.
