Methods are disclosed in which an electrically conductive substrate is immersed into an electrodepositable composition, the substrate serving as an electrode in an electrical circuit comprising the electrode and a counter-electrode immersed in the composition, a coating being applied onto or over at least a portion of the substrate as electric current is passed between the electrodes. This second wireless channel is aimed to transmit status, control information or to send any type of information from external systems, such as e-mail and voice-mail systems, to the subscriber to activate optical or acoustic indications or message display on the subscriber telephone set or external devices. The first and second arms are slidably moveable with respect to each other. The end cone insulator comprises insulation and binder defining a passage therethrough.
