First Claim
1. A method of testing a system having a plurality of components, each component having at least one radio frequency (RF) port, and a plurality of cables connected to the at least one RF port of the plurality of components, the method comprising:
- applying a first voltage indicating at least a first logic state to a first RF port of a first component of the plurality of components, wherein the first RF port is configured to carry RF signals, and the first component comprising a direct current (DC) blocking circuit causing the first voltage applied to the first RF port to not impact the RF signals carried by the first RF port by providing a high impedance higher than an impedance of the RF signals to the first RF port and blocking the high impedance from the RF signals and circuits related to the RF signals;
scanning multiple input ports of the plurality of components by a controller;
recording by the controller an RF link between the first RF port and an input port among the scanned multiple input ports corresponding to the applied first logic state at the first RF port of the first component; and
providing a plurality of remote units capable of transmitting wireless signals into respective coverage areas of the plurality of remote units, and for receiving wireless signals from their respective coverage areas, the plurality of remote units being optically connected to at least one of the plurality of components, wherein the plurality of remote units are optically connected to the at least one of the plurality of components by a cable of the plurality of cables including at least one optical fiber.

Abstract
Connectivity between components in a system is monitored by applying a low voltage at one end of an RF cable, interpreted as a “0” logical state, and determining whether a similar voltage appears at the other end of the cable. If the cable is connected properly, the DC voltage applied at one end will appear at the other end and a proper indication is generated. If the expected voltage level does not appear at the other side, it means that RF connection was not correctly established and an alert is generated. Test systems for testing connectivity may include a first component comprising at least one port, at least one capacitor, and at least one resistor for providing high impedance. A controller provides a first logic state to the at least one port, scans multiple input ports of the system, and records a link corresponding to the applied first logic state.
