Abstract: A programmable channel scanning and acquisition method for a cable modem first performs a fast scan and then a slow scan to identify channels supporting cable modem services. The fast scan involves only a check of the cable modem AGC lock. A list of potentially operational channels is assembled and scanned. The list includes, in order of preference, the last known good channel, golden channels that are likely to support cable modem services, “learned” golden channels consisting of previous last known good channels, and other channels within the frequency plan range. The list omits channels on a “black list” known not to be operational and channels outside of the frequency range, except during registration. The method may be optimized by the setting of various parameters for operation in a DOCSIS or EuroDOCSIS environment.

Abstract: A member of sheet material has cut out portions and fold lines, so that when it is folded up and central areas attached together to form a spine display areas are provided in different planes. The display area may be used to display a photograph or picture having with any one of a large range of sizes. The bottom edge of the member may have a V-shaped cut-out so that it leans back slightly when erected.
