Page 15: Wiring The Rt
950-779-115-02, Revision 02 Installation and Turn-up IRING THE Wiring the RT consists of three major steps: • attaching the frame ground wire • attaching the HDSL Tip and Ring wires • attaching the subscriber line wires Before setting up the equipment, select a location that will allow sufficient access to wiring connections from the telco access door. - Page 16 Installation and Turn-up 950-779-115-02, Revision 02 Attaching the Frame Ground, HDSL and Subscriber Line Wires To install the RT wires, do the following: This RT does not provide primary protectors on the HDSL or subscriber pairs. The primary protection for HDSL pairs must be an integral part of the premises wiring. If the subscriber wiring is routed outside of the premises for any reason, then primary protection for subscriber pairs must also be an integral part of the premise wiring.
- Page 17 950-779-115-02, Revision 02 Installation and Turn-up For the FGND and Subscriber Line wires, pivot the IDC connector upward, then insert the wire pair through the tip and ring holes (see Figure 8). Each wire entry hole accepts one unstripped solid copper wire 22-24 American Wire Gauge (AWG) with a maximum insulation diameter of 1.52 mm.
