Chapter 6 Connecting Central

Safety Precautions

Use 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 wet
locations.
! Never touch non-insulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.

Loop Start Lines

Using one pair twisted #24 AWG (0.5mm) or #26 AWG (0.4mm) jumper wire, cross-connect each
loop start C.O. line to the Trunk B or 8TRK port of your choice

AC15 Tie Lines

Using two pair twisted #24 AWG (0.5mm) or #26 AWG (0.4mm) jumper wire, cross-connect each
tie line to the AC15 card port of your choice

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
the 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 of
C.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 OPX
ports are set for C.O. ring in MMC 208. The telephone company service facility interface code for
OPX circuits is OL13C.
