Abstract: An apparatus for verifying port and slot assignments of cable bundles that extend from a telephony filtering device, including Digital Subscriber Line (DSL) infrastructure. The apparatus may have a circuit board that inserts into a vacant slot of a frame of DSL equipment. The circuit board (sometimes called a LC circuit board) provides a connector that provides electrical continuity from a voltage driven indicator to, e.g. a slot-to-slot interface. One lead to the indicator may be held to a high voltage by a voltage source. A remaining lead, or probe input, may be connected to a common ground to cause the indicator to illuminate. Frequently, the common ground circuit closure may occur at a Main Distribution Frame (MDF). Such a circuit board may be installed in a data only shelf, i.e. wherein Line Cards (LC) that ordinarily populate the shelf support data traffic that arrives via the slot-to-slot interface.

Abstract: A light guide is disclosed having a critical angle, wherein light enters the light guide in an input direction. A reflector reflects light using total internal reflection in a lateral direction. A second reflector reflects light using total internal reflection in a second lateral direction. A third reflector reflects light from the lateral direction upward. A fourth reflector reflects light from the second lateral direction upward.

Abstract: A system is disclosed to operate within a multiple access system having remote devices that are located at varying distances from a central device using timing advance commands. The invention relates to inserting varying units of delay in the signal path from remote device to central device, wherein the units of delay are a fraction of the smallest timing advance duration. By scanning through the units of delay, thus triggering a timing advance command, the invention infers the distance of the remote device signal path more accurately than would be obtained by relying on timing advance settings alone. Several levels of resolution can be used to scan successively narrower regions.

Abstract: An antenna configuration for a mobile communication device. The antenna configuration includes at least a first antenna configured so that the first antenna may be mounted near or between a speaker and a earpiece of a mobile station. In an embodiment of the invention, the first antenna comprises a substantially flat conductor including at least one hole for passing sound from the speaker to the earpiece of the mobile station. The first antenna is configured to receive GPS signals. A second antenna is implemented on the mobile station to transmit and receive cellular transmissions.
