6-1Chapter 6 Connecting CentralOffice CircuitsSafety PrecautionsUse caution when installing or modifying telephone lines. To limit the risk of personal injury, al-ways follow these precautions before connecting Central Office (C.O.) circuits:● ! Never install telephone wiring during a lightning storm.● ! Never install telephone jacks in a wet location unless the jack is specifically designed for wetlocations.● ! Never touch non-insulated telephone wires or terminals unless the telephone line has beendisconnected at the network interface.Loop Start LinesUsing one pair twisted #24 AWG (0.5mm) or #26 AWG (0.4mm) jumper wire, cross-connect eachloop start C.O. line to the Trunk B or 8TRK port of your choice (Figures 6-1 and 6-2).AC15 Tie LinesUsing two pair twisted #24 AWG (0.5mm) or #26 AWG (0.4mm) jumper wire, cross-connect eachtie line to the AC15 card port of your choice (Figure 6-3).Off Premise Extensions (OPX)Using one pair twisted #24 AWG (0.5mm) or #26 AWG (0.4mm) jumper wire, cross-connect sin-gle line telephone (SLT) extensions to telephone company OPX circuits (Figure 6-4). Circuits onthe SLI card are specifically designed to meet telephone company requirements for OPX use.These circuits are provided with the same over-voltage and over-current protection as that ofC.O. line circuits. Using SLTs on any other SLI card or a KDB-SLI requires the installation of ex-ternally mounted protection devices.There is no special programming required for OPX use; however, it is suggested that the OPXports are set for C.O. ring in MMC 208. The telephone company service facility interface code forOPX circuits is OL13C.
