Various embodiments of the present invention are generally directed to an apparatus and associated method for generating a reference voltage with dummy resistive sense element regions. In one embodiment, the device comprises first and second bracket members. A computer operator located at the control computer, through the use of remote control software installed on both the control computer and the RDU, operates the RDU in order to conduct testing of the test modem, performance comparisons with the reference modem, modifications to the RDU, and installation of new modem software on the RDU. There is an opening in the rear of the splice panel for admitting cables for bolding splices between optical fibers forming the cable. Responsive to a determination that the service using device is prohibited, the access point blocks the service using device from receiving the service.
