PRL-770 by applying + 100 V dc to the HDSL pair. The COLU also initiates a start-up after a momentary short has been applied to the HDSL pair. The COLU responds with start-up voltage immediately upon removal of the short. - Page 8 Install the PRL-770 RT Enclosure. Use the two #10 x 1.5" wood screws and flat washers provided in the PRL-770 Mounting Kit to attach the PRL-770 RT enclosure to the side of the customer residence (see Figure 4). For installation on stucco or other suitable surface, use the two PairGain provided #10 x 1"...
