A system that incorporates teachings of the present disclosure may include, for example, a server comprising a controller to capture routing data representative of routing changes associated with a plurality of networks, and compare the routing changes to detect discrepancies in route lists associated with the plurality of networks. The core and the cladding are selected to provide a spectral attenuation at 1550 nm of less than 0. The load bearing surfaces are in contact to transfer load, and the teeth of the first and second members are in engagement to provide non-slip rotation. During normal display, vertical scanning of the screen is performed by the first gate signal line driver circuit. The enclosure has a first opening configured to fit around the heat sink and at least one second opening.
