摘要： The invention relates to an arrangement for retaining a printed circuit board (1) at a frame (5, 6). Connectors (2) are mounted on the PCB (1) and have electrical connection pins (3) connected to electrical conductors in the PCB (1). The connectors (2) are elongate and have end portions (4) bearing against the front of the PCB. In accordance with the invention, the frame (5, 6) has holders (7, 8, 9) coacting with the end portions (4), these holders retaining the connectors (2) and PCB (1). The frame (5, 6) has a tongue (7) engaging against the front of the end portion (4), and a movable support (8) is kept in engagement against the back of the PCB (1) behind the tongue (7) with the aid of a screw (9). The forces occuring when a means complementary to the connector (2) is connected to the connector are transferred to the frame (5) by the connector (2), and the invention thus allows the PCB to be made thin. This has, inter alia, the advantage that the capacitance between the different conducting layers of the PCB will be large, and the PCB will be well impedance-adapted and can have a high packing density of conductors without cross talk problems.

摘要： The invention relates to a pin (21) for connecting an electrical conductor (2) to a PCB (4). The pin has a first part (24) thrust into a hole in th PCB and a second part (26), to which the electrical conductor (2) is connected by a sliding contact (8). The cross-sectional dimension (d2) of the second part (26) is greater than the cross-sectional dimension (d1) of the first part (24), and between these parts the pin (21) has a shoulder (27) with sharp edges. The hole in the circuit board is coated with metal which is connected via tabs (22) to electrical conductors (3) of the PCB (4). The pin (21) is soldered in the hole with the aid of soldering metal (25) and flux. When the flux is heated it creeps along the surface of the pin. During soldering, the shoulder (27) with the edges prevents the flux reaching the second part (26) of the pin (21), the second part having contact surfaces (29) on the pin (21) against the sliding contact (8) and where the flux would be a contact resistance. The pin (21) has the advantage that its first part (24) is narrow and that the tabs (22) can have a small outside diameter. There is thus created room for a large number of conductors (3) between two adjacent pins (21).

摘要： In the determination of the angular offset between axial asymmetries, in particular between optically inhomogeneous regions in optically transparent bodies, such as stress concentration zones (7) of optical PM-fibers or fiber cores (3') of optical twin core fibers (1'), located in arbitrary angular start positions, the ends of the fibers are illuminated during rotations thereof to different angular positions around their longitudinal axes. For different angular positions the difference (h) is then determined between light, which has passed through the fiber end and in its position corresponds to the central part of the fiber, and light, which has passed through the fiber end and in its position corresponds to the region of the fiber located immediately outside the central part. These differences (h), considered as functions of the rotation angle, constitute curves for the fiber ends. The curves are compared and are translated in a parallel way to a new angular position, where a maximum agreement is obtained in the shape of the curves. The angle between the curves in this angular position gives the angular offset between for example the plane (8, 8'') through the stress zones (7) or the fiber cores (3') in the start positions thereof and this angle is used for rotating the fiber ends, so that these planes (8, 8'') and thus the stress zones (7) or the fiber cores (3') in the fiber ends will be aligned with each other.

摘要： The invention relates to a method of receiving in a GSM-network data for supplementary services in MSC/VLR which have been signalled via the protocol MAP between HLR and MSC/VLR. MAP contains sequences of "containers" for supplementary services, where respective "containers" always include a parameter that indicates the service to which the contents of a respective container relate, together with the data that varies from service to service. This parameter is always located in the same position internally within the "container". The method includes a function whose purpose is to analyze syntactically subscriber data received in MAP, to the extent that respective supplementary services can be identified. When the correct supplementary service has been identified with the aid of the data type SS-code, it obtains access to the contents of the container. Respective supplementary services analyze syntactically those data types that are included in the container in accordance with a structure which is known only in a respective supplementary service. Data is then stored locally for each supplementary service in MSC/VLR.

摘要： Methods and devices are proposed for handling a buffer (11) in packet networks are proposed, particularly in regard of loss and delay of packets. The packets are supposed to belong to predetermined or implicitly given loss priority classes and delay priority classes. When a packet arrives to the buffer (11) the class of the packet is determined, both for loss and delay. For each loss priority class there is a predetermined threshold value (T1, TBusy, TIdle, T3, TL) and the total filling level (M) of the buffer, i.e. the total number of packets stored, is compared to the threshold value of the loss priority class to which the received packet belongs. If said threshold value (T1, TBusy, TIdle, T3, TL) is larger than said filling level (M), the packet is buffered in order to be forwarded, and otherwise it is lost. In the determination if said packet is to be buffered or lost the delay priority of the packet is not taken into account. In the forwarding of packets from the buffer (11) those packets are chosen in the usual way, which belong to higher delay priority classes before packets belonging to lower delay priority classes, where this is performed in such a way that packets belonging to all delay priority classes can be warranted a specific minimum service level. It is achieved by associating each such class with a maximum time period, within which at least one packet of the delay class considered will be forwarded, if such a packet is available in the buffer (11).
