Abstract: An equipment rack has a strengthened base and folded side members to provide Zone 4 earthquake protection. When the rack is mounted on a support surface, the mounting bolts securing the rack are overtightened so as to distort the base member and thus prestress the structure. This improves rigidity when the rack is subjected to earthquake vibration.

Abstract: A directory-based network comprises user-callable network elements, at least one directory server, and at least one call/process server. The call/process server comprises several decoupled engines including a policy engine which upon system initialization or upon request retrieves a plurality of policy scripts from a directory server and constructs from them an adaptive context-sensitive policy tree. Upon user call to a network element requesting a service, an agent of the call/process server, which agent is located in the network element, forwards an admission request to the call/process server which executes policy tree in the context of the request and of the current state of the network as reflected in the directory server and in said several decoupled engines of the call/process server. An admission reply is returned to the network element, the contents of which are retained in service-specific control block in the network element and used to control the execution of the request. Policy scripts can easily be entered, deleted, or modified and a new policy tree built immediately.

Abstract: In a duplex WDM transmission system, an optical amplifier (13) that uses different amplification paths (22, 25) for amplification of the different directions of signal propagation requires filters to keep the loop gain less than unity for all wavelengths within the amplification waveband. Simple high-pass and low-pass filters can be used when red channels are used for signals propagating in one direction, and blue ones for those propagating in the other. Comb filters (34, 37) are, however, required for use in any optical amplifier employed in such a transmission system using any form of interleaved form of channel allocation in place of the red/blue allocation. Examples of such amplifiers are described, these amplifiers having filters possessing a tandem arrangement of an optical isolator (41) and a series of Bragg reflection gratings (42).

Abstract: 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.

Abstract: 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.

Abstract: 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.
