Abstract:
A field reconfigurable muxponder for use in an optical transport system. The muxponder includes one or more tributary cards, where each tributary card is adapted to receive an optical data signal and conditions the optical data signal into an intermediate data signal constituted in accordance with a tributary interface format. In this way, the muxponder is able to aggregate optical data signals having different protocols and/or different data rates. The muxponder further includes a chassis that is adapted to receive a predefined number of tributary cards and outputs an optical system signal independently from the availability of the optical data signals from the tributary cards. The tributary cards and the chassis integrally form one line card.
Abstract:
Bench planes of different sizes having interchangeable components and an adjustable frog providing full blade support with a frog foot that extends through the plane body mouth to terminate co-planer or nearly co-planer with the sole. The rear plane handle or tote is captured between and secured soley to tines projecting from the frog that is adjustably secured to alternative sizes of plane bodies in a manner permitting forward and backward adjustment of the frog position without removing the plane blade. Superior lateral blade position control is provided by set screws in the plane body and contacting blade side edges. Adjustments in the blade cutting angle without modifying the angle at which the blade is held by the frog in the plane may be made by forming a front bevel on the front surface of the blade.
Abstract:
A dividing rule that allows the user to divide a workpiece into equal divisions with heightened accuracy and ease. The dividing rule is a plate with pins attached at the corners of the plate which help position the plate on the workpiece. Holes marked with appropriate divisions are located on the plate so that the user, to partition the workpiece into equal divisions, simply marks the workpiece using the holes that coincide with the desired number of divisions.
Abstract:
A network diagnostic system is provided for an optical transport network having a plurality of network elements. The network diagnostic system includes at least one network element having a network diagnostic operation integrated therein and operable to perform the network diagnostic operation, thereby determining a network performance characteristic associated with the optical transport network; a wayside communication subsystem interconnecting the network elements residing in the optical transport network; and a network diagnostic device in data communication with the at least one network element and operable to initiate the network diagnostic operation at the network element.

Abstract:
A spokeshave providing an easily used depth of cut adjustment that is simple, effective and requires no extra tool or blade removal for adjustment. The blade of the spokeshave is mounted on two posts that project normal to the back of the blade, and the posts are received in structures adjustably positioned within the spokeshave body. Adjustment of the positions of the post-receiving structures cause the blade to move toward or away from the body.
Abstract:
A method is provided for isolating faults in an optical network having a plurality of partial regenerators. The method includes: transmitting an optical signal through the optical network; determining an error rate for the optical signal at an egress point of the optical network; sequentially introducing a dither control signal into the optical signal at each of the plurality of partial regenerators; and monitoring the error rate for the optical signal at the egress point of the optical network; thereby isolating where a fault occurs in the optical network.
