摘要： An apodised refractive index grating is recorded in a photosensitive optical fibre by forming first and second component interference patterns with different pitches, that are recorded in the grating such as to result in apodisation. The component patterns (16, 17) are spatially in phase in a central region and move progressively out of phase towards the ends of the patterns. The patterns may be recorded sequentially or concurrently. The fibre may be stretched one or cyclically.

摘要： In a method of routing a packet carried on a network having a generally regular topology, the packet is received at a node (N) where a local routing decision is made. The packet is output in a direction selected according to the routing decision. The packet carries in addition to a destination address a directional flag indicating explicitly the preferred direction of onward travel and the routing decision is made using this flag. Several flags may be used, corresponding to different dimensions of the network.

摘要： An optical network includes optically pumped waveguide amplifiers (23). A supervisory signal uses the amplifier's pump wavelength (23), e.g. APPROX 1480 nm if EDFAs are used. Substandard pump diodes may be used to generate the supervisory signal. A repeater station for the network includes an optically pumped waveguide amplifier (23) and a bypass route (27, 28, 29, 30, 31) for supervisory signals. In a described example the bypass route comprises an optical supervisory signalling means (31), an optical receiver (29), a first wavelength division multiplexer (27) for coupling a supervisory signal from a transmission medium and applying it to the optical receiver, processing means (30) for processing supervisory signal data received by the receiving means and controlling the optical supervisory signalling means to generate a further supervisory signal, and a second wavelength division multiplexer (28) for coupling the further supervisory signal into the transmission medium, wherein the first and second wavelength division multiplexers are arranged one on either side of the waveguide amplifier.

摘要： In a telecommunications network of the kind including service control points (6) which permit differing services to be provided to customers (5), centralised storage of data defining service provided to each customer is avoided. Whenever an update of service provided to a particular customer is required, such update is carried out centrally at a service creation point (10, 12). In the service creation point, data defining the current executable code deployed at the service control point (6) for that customer is recovered to enable recreation of the existing executable code to be carried out. The current code may then be modified regardless of which service creation point (10, 12) is carrying out the modification.

摘要： Portions of recorded speech waveform (e.g. corresponding to phonemes) are combined to synthesise words. In order to provide a smoother delivery, each voiced portion of a waveform portion has its amplitude adjusted to a predetermined reference level. The scaling factor used is varied gradually over a transition region between such portions and between voiced and unvoiced portions.

摘要： A voice activity detector (26) comprising an input for receiving an outgoing speech signal transmitted from a speech system (2) to a user and an input for receiving an incoming signal from the user. Both the outgoing and incoming signals are divided into time limited frames. Means (263) are provided for calculating a feature from each frame of the incoming signal and for forming a function of the calculated feature and a threshold. Based on the function, it is determined whether or not the incoming signal includes speech. Means are provided to determine the echo return loss during an outgoing speech signal from the interactive speech system and to control the threshold in dependence on the echo return loss measured.

摘要： Faults occurring in a telecommunications system (21) are monitored identifying their time of onset and reporting them to an operator through an interface (16) if they have not cleared within a predetermined interval. Transient faults, which do clear within that interval, are not reported directly, but only if such faults occur more frequently than a predetermined rate. This is determined by establishing a scan interval, and an analysis period equal to a plurality of scan intervals, monitoring the system (21) continuously for the occurrences of faults, and storing their times of occurrence in a store (8). At the end of each scan interval, the number of occurrences of the fault during the analysis period which ends at the end of the scan interval are counted by a counter (11). If the number of occurrences of the fault in the analysis period is equal to or greater than a threshold value selected by user input (16), an alarm indicator (17) is activated. This allows isolated transient faults to be disregarded, allowing the user to concentrate on recurrent intermittent faults.
摘要翻译：检测在电信系统（21）上发生的故障，记录它们发生的时刻，并且如果接口（16）通知操作员它们的存在，如果它们在预定的时间间隔之后没有消失。在此时间间隔内消失的瞬态故障不会直接传达，但只有在频率高于预选频率时才会发生。该结果是通过选择等于多个扫描间隔的扫描间隔和分析周期，连续地监视系统（21）发生故障并在发生时进行记录来获得的。发生在存储器（8）中。在每个扫描间隔结束时，计数器（11）在扫描周期结束时的扫描周期内发生了多少次故障。当分析期间的故障次数等于或大于用户在输入装置（16）中输入的阈值时，激活警报（17）。这允许用户忽略瞬态孤立故障并关注周期性间歇故障。
