Title: Rail fixings
Inventor: CLARKE JOHN BARRY
IPC: E01B19/00
Filed: 1998-09-18
Abstract: A damper (18) for reducing the track noise emitted by a rail system comprises a deformable material (20) attachable to a surface of the rail, incorporating a plurality of elongate discontinuous resonant members (22, 24) of a stiff material as compared to the deformable material, sized to contain at least two resonant frequencies in the range of interest. The resonant members (22, 24) are suitably of steel or other metallic material. They can be of different profile, to form a resonant system with at least two resonant frequencies in the relevant frequency range. They are suitably embedded in the deformable material (20), to ensure adequate vibrational transfer from the rail to the resonant members and also provide environmental protection. The deformable member (20) is visco-elastic, for example rubber or a rubber-like material. This may be preformed and glued to the rail (10), or it can be cured in place on the rail. The damper (18) is positioned on the rail (10) at the junction between the web (14) and the foot (16) of the rail. One resonant member (22, 24) can be an elongate angled section, the angle preferably matching the angle between external surfaces of the head (12) and foot (16).

Title: Hierarchical schedules for different atm traffic
Inventor: OZVEREN CUNEYT M
IPC: H04L12/56
Filed: 1998-11-17
Abstract: An ATM scheduler in accord with the invention supports multiple transmission traffic types (e.g. CBR, VBR and ABR) for each of a plurality of virtual path connections (VPCs) on an ATM link. The scheduler maintains one or more scheduling tables defining the hierarchy of traffic types and the scheduling for each type of traffic within each virtual path. In each cell transmit time, one VPC is identified as assigned to the opportunity to transmit in the respective cell transmit time. Each virtual path connection supports at least one type of high priority traffic, such as constant bit rate (CBR) traffic, over a plurality of virtual circuit connections. The scheduler determines if there is a high priority service virtual circuit connection (VCC), from among those associated with the identified VPC, and that has been assigned the current cell time slot. If the scheduling device identifies such a VCC, then the scheduler provides the transmit opportunity for that VCC. For example, if the VCC has CBR service, a cell for that VCC is transmitted over the link in the respective cell transmit time. If the VCC has variable bit rate service, a cell is transmitted if there is in fact a cell ready to send over that VCC. Also, during processing for each cell transmit time, the ATM  scheduler accesses a link list. The link list identifies at least one available bit rate (ABR) service type VCC. The link list identified is one associated with the indexed virtual path connection. The ATM scheduler preferably transfers the accessed link list to an ABR work list associated with the indexed VPC. During each respective cell transmit time, if the processing relating to the high priority service(s) did not result in cell transmission in the time slot, the scheduler examines the ABR  work list to identify an ABR service type VCC for which there is a cell that is ready to transmit, and the cell for that circuit is transmitted over the link in the respective cell transmit time.

Title: Telecommunications network synchronization for data services
Inventor: LEMIEUX YVES
IPC: H04J3/06
Filed: 1999-07-30
Abstract: A star network type topology is imple-mented or a network synchronization sys-tem wherein synchronization information ra-diates from a centralized primary reference source (46) comprising the global position-ing system (GPS). A GPS receiver (54) in-stalled at each mobile switching center (14) and base station (18) of a wireless commu-nications network supplies a stratum 1 clas-sified clock pulse to a local clock (40). The local clock trains to this clock pulse and gen-erates a corresponding stratum 1 classified synchronization clock pulse for controlling timing operations of the mobile switching center or base station. In the event the GPS  primary reference source fails (72) or its ac-curacy degrades (74), a change is made to a tree or linear network type topology wherein the synchronization information flows down-stream from the mobile switching center lo-cal clocks to the base stations. Operation of the network synchronization system is co--ordinated through a synchronization man-ager (52) maintained by the transport net-work management system (28) of the net-work. Highly accurate synchronization us-ing these topologies supports the provision of value added services such as mobile station locating (102) and information time stamp-ing.
