摘要： A method is provided for forming a capacitor structure for a memory element of an integrated circuit. The method comprises providing a first conductive electrode, forming a layer of a first dielectric material thereon, opening a via hole through the dielectric layer, providing within the via opening a capacitor dielectric having a higher dielectric strength than the first dielectric, the capacitor dielectric contacting the first electrode, planarizing the resulting structure and then forming a second conductive electrode thereon. Preferably, when the second dielectric comprises a ferroelectric dielectric material, sidewalls of the via opening are lined with a dielectric barrier layer to provide diffusion barrier between the ferroelectric and first dielectric layer. Advantageously, planarization is accomplished by chemical mechanical polishing to provide fully planar topography. The method provides a capacitor of a simple, compact structure which may be integrated with CMOS, Bipolar and Bipolar CMOS processes for submicron VLSI and ULSI integrated circuits.

摘要： The packet routing system disclosed allows for efficient transfers of IP streams from router to router with use of supertrunking. The router (102) that receives (502) an IP stream (220) set for transmission on a supertrunk (112), individually inputs the IP packets, determines (504) the logical output port corresponding to the IP stream, assigns each IP packet to a physical output port within the logical output port with use of a load balancing function, encapsulates each IP packet within a supertrunk header (506) comprising an IP stream identifier and a packet sequence identifier and an IP header that has identical source and destination addresses as the original IP packet, and forwards (510) the encapsulated packets to the receiving router via a plurality of physical links. The router (104) that receives the encapsulated IP packets then re-orders the packets into the proper order with use of a sorting algorithm, removes the IP and supertrunk headers, and outputs an IP stream similar to that input to the original router.

摘要： In a data communications network in which virtual circuits and encapsulated virtual circuits may be established to carry calls from source terminals to destination terminals through network interfaces, information describing each virtual circuit is returned to, and stored at, the source. Should a virtual circuit or an encapsulated virtual circuit be interrupted, the destination holds the call open while the source requests reestablishment of the virtual circuit or encapsulated virtual circuit, by providing the stored description thereof through an alternate network interface. Upon reestablishment of the virtual circuit or encapsulated virtual circuit, the call proceeds with, or without, loss of data.

摘要： Constrained operation performance of exchanges (50) and switches (16, 216) of wireline communication systems (10) is mitigated and single entry point management of the system maintained through the provision of a distributed multi-service hub (MSH) sub-net (350) architecture in which individual MSHs (302-308) have hidden point codes (1001-1003). A signalling server (352) is able to translate an address of the MSH sub-net into a point code associated with an MSH entry point into the MSH sub-net, while dialled digit information pertaining to a service or party identifies a related MSH exit point from the MSH sub-net (350). A path can therefore be established, with the signalling server (352) further required to ensure that the hidden point code associated with the MSH exit point is translated back to the address of the MSH sub-net in onward routing of signalling messages to the dialled service or party.
An intermediate element manager EM 2 (312) isolates a management server OSS (54) from element managers (314-322) associated with the control of individual MSHs (302-310), with the intermediate EM 2 (312) therefore providing a single address point to the OSS (54) while itself appearing as an OSS to the element managers (314-322) of individual MSHs (302-310). Signalling and management functions can therefore be consolidated at the intermediate EM 2 (312) to increase efficiency and reduce overhead.摘要翻译： 减轻有线通信系统（10）的交换机（50）和交换机（16,216）的约束操作性能，并通过提供分布式多业务集线器（MSH）子网（MSH）子网维护系统的单入口点管理 350）架构，其中各个MSH（302-308）具有隐藏点代码（1001-1003）。 信令服务器（352）能够将MSH子网的地址转换为与MSH入口点相关联的点代码进入MSH子网，而与服务或方有关的拨号数字信息标识相关的MSH出口 来自MSH子网（350）。 因此，可以建立路径，进一步需要信令服务器（352）以确保与MSH出口点相关联的隐藏点码转换回到MSH子网的地址，从而将信令消息向前路由到被拨号的 服务或派对 中间元件管理器EM2（312）将管理服务器OSS（54）与与各个MSH（302-310）的控制相关联的元件管理器（314-322）隔离，其中间EM <2 （312）因此向OSS（54）提供单个地址点，同时其自身作为OSS呈现给单独MSH（302-310）的元件管理器（314-322）。 因此，信令和管理功能可以在中级EM2（312）中进行整合，以提高效率并减少开销。

摘要： A base station (14a,14b) includes a multiple technology vocoder (28) having a plurality of vocoder resource modules (34-42) that are individually selectable to facilitate support by the base station of corresponding communication protocols serviceable by the base station within each coverage area. A buffer and associated buffer manager (30, 46) are responsive to messages such that memory space is partitioned appropriately to support a specific nature of the communication protocol identified within the message. A selection manager (32, 44) then acts to provide a path between buffered messages and an appropriately selected vocoder resource module. In an inter-cell/protocol handoff between base stations having dissimilar vocoders, support of a subscriber unit operating using a first communication protocol is maintained at a base station not having the necessary vocoder by the re-routing and remote processing of messages from the subscriber unit to a secondary base station able to provide the requisite vocoder processing capability.

摘要： A packet based telecommunication system, such as ATM, comprises a main data path and at least one bypass path, for bypassing a portion of the data path, the portion and the respective bypass defining a protection domain, the system comprising nodes for each of the domains, for monitoring respective domains and for issueing alarms in the form of packets, to other nodes downstream, with a domain identifier indicating the respective domain in which the alarm originated. At a given one of the nodes an alarm issued from a node upstream of the given node and a corresponding identifier, are detected. At the given node it is determined whether to trigger a rerouting of the data along one of the bypass paths which bypasses the domain monitored by the given node, on the basis of the detected domain identifier. Using the identifier, downstream nodes can determine more easily whether the alarm is caused by a domain which has a bypass path triggered by another node upstream. Thus the problem of unnessary triggering, can be overcome without the considerable additional complexity, cost, and speed penalty of having nodes which must extract the alarm, modify it and send it on.
