Abstract: An apparatus for automatically discovering a cable interconnection topology in an optical communications network between an optical network node and a CSI expansion shelf employs a memory module attached to each end of a fiber optic cable connecting the node and the shelf. A connector houses a rewritable memory module that stores identification information regarding the type of cable and is capable of storing node and port identification regarding the port to which the end to which the memory module is attached, as well as the node and port identification about the port to which the other end of the cable to which the memory module is attached. The port and node connected information is then broadcast via the control channel to all appropriate entities, such as the master node, or other entity maintaining network topology information.

Abstract: An apparatus for folding and sealing a sheet having a pressure sensitive adhesive positioned thereon includes a first roller. The apparatus also includes a second roller which is positioned in operative contact with the first roller during advancement of the sheet between the first roller and the second roller. The apparatus also includes a third roller having (i) a roller surface, and (ii) a sealing protrusion extending from the roller surface. The apparatus further includes a sheet stop positioned to halt forward movement of the sheet during advancement of the sheet between the first roller and the second roller and subsequently create a buckle in the sheet which is advanced into a roller nip defined by the first roller and the third roller. The sealing protrusion of the third roller is positioned in operative contact with the first roller during advancement of the sheet between the first roller and the third roller.
