摘要:
Apparatus and methods for managing communication system resources are disclosed. Based on status information received from a resource itself or from other sources, an operational status of a maintenance resource to perform a predetermined maintenance operation on a target communication system resource, for example, may be determined. Access to use resources in performing operations may also be controlled. Resource access is granted or denied based on an availability status of a resource. Other parameters such as relative priorities of a new request to use a resource and a current operation for which access to use the resource was previously granted may also be used in determining whether to grant access to use a resource. A resource may be reclaimed for a higher priority operation for instance. Redundant or alternate resources may also be identified where a resource is not operational or otherwise not available.

A cover for use on a toaster is disclosed. The cover serves to minimize heat losses and comprises a plate slightly smaller in size than the top of the toaster, and means for hingedly mounting the plate on the top of the toaster, so as to cover the bread slots. The plate is preferably embossed in the shape of an inverted pan, so as to leave a predetermined space between the embossed portion of the cover and the top of the toaster.

A toaster of the pop up type that is provided with a pivoting cover to save energy and toasting time and in which there is an upwardly displaceable cover lifting device or rod characterized by being arranged to fully open the cover without the toasts having to push up the cover to open it and without having to lower the bread carrier to close the cover. This toaster comprises a pop up device or member that upwardly pushes or propels the cover lifting rod but is not connected to be lowered with it to retract the cover lifting rod and close the cover.

A hybrid IP/ATM DSLAM and method are provided for hybrid IP/ATM DSL access multiplexing. While traversing a DSLAM, ATM traffic over ATM network infrastructure and GigE/IP traffic over GigE/IP network infrastructure may be recast into crossover GigE/IP traffic and crossover ATM traffic respectively, and routed to the opposite kind of network infrastructure.

Distributed communication equipment architectures and techniques are disclosed. A host system includes an expansion unit through which control information and communication traffic may be exchanged with an expansion system. The expansion system is thereby controllable by a controller at the host system, significantly simplifying the design and reducing the cost of the expansion system. The expansion unit for a host system may also provide one or more configurable communication link interfaces. Each configurable interface may be independently configured as a network-side interface for connection to upstream communication equipment or as an access-side expansion interface for connection to an expansion system, allowing provisioning of network and access interfaces at the host system as needed.
