Appl. No.:

09/325187

Inventors:

Stephen J. Brolin - Livingston NJ
Robert W. DeMarco - Whippany NJ

Assignee:

Fujitsu Network Communications, Inc. - Richardson TX

International Classification:

H04L 1244

US Classification:

370218, 370352, 3703951, 370401, 370407, 370425, 709201, 709221, 709249, 709252

Abstract:

An architecture for a SONET network element, such as a hybrid STM/ATM add-drop multiplexer. The disclosed system includes an interconnection system for a network element, including a line unit slot, a switch fabric slot, and two or more service unit slots. The line unit slot is connected as a hub to the switch fabric slot and the service unit slots in a first star interconnection configuration. The switch fabric slot is connected as a hub to the line unit slot and the service unit slots in a second star interconnection configuration. The star interconnection configurations provide fault isolation between different units, and allow for replacement of failed units without interfering with the links of other units to the hub. In a preferred embodiment, the switch fabric slot and one of the service unit slots comprise the same slot, thus permitting flexible configuration of the device within a minimal space. In a further illustrative embodiment, a control unit slot is provided in the interconnection system, and connected as a hub to the line unit slot, the switch fabric slot, and the service unit slots to form a third star interconnection configuration.

International Classification:

E04B 148

US Classification:

403256, 403260, 403378, 403373

Abstract:

A device for securing an object to the end of a hollow post or pipe, such as a parking meter head, comprising a bar capable of being transversely disposed within the hollow post or pipe by passing substantially the entire length of the bar through an opening in the side of the hollow post or pipe, the end of the bar first passed through the opening being configured to be received by an alteration in the inside surface of the hollow post or pipe located opposite the opening, the bar being further configured so as to substantially impede its rotation when disposed in the hollow post or pipe and to accept a fastener inserted through the end of the hollow post or pipe for securing the object to the bar.

The star interconnection configurations provide fault isolation between different units, and allow for replacement of failed units without interfering with the links of other units to the hub. A service unit is provided including a first backplane interface for connecting with an ATM star interconnect configuration within the network element, and a second backplane interface for connecting to an STM star interconnect configuration within the network element.

H04J 14/08

US Classification:

370219, 370401, 370407, 370425, 398 2, 398 58

Abstract:

A network element including an active/standby pair of line units, an active/standby pair of switch fabric units, at least one service unit, and a management and control unit. Each line unit maintains data communications using a first communications protocol. Each switch fabric unit maintains data communications using a second communications protocol. Each service unit includes a first backplane interface supporting the first communications protocol, and a second backplane interface supporting the second communications protocol. The management and control unit provides a control infrastructure for selectively communicating data units between the active/standby pair of line units, the active/standby pair of switch fabric units, and the service unit, responsive to provisioning information or information contained within the respective data unit.
