PART 5. CONNECTING TELCO CIRCUITS
5.1 SAFETY PRECAUTIONS
To limit the risk of personal injury, always follow these precautions before connecting
TELCO circuits:
a. Never install telephone wiring during a lightning storm.
b. Never install telephone jacks in a wet location unless the jack is specifically
designed for wet locations.
c. Never touch non-insulated telephone wires or terminals unless the telephone line
has been disconnected at the network interface.
d. Use caution when installing or modifying telephone lines.
5.2 LOOP START LINES
Using one pair twisted #24 AWG or #26 AWG jumper wire, cross-connect each loop
start C.O. line to the Trunk B, Trunk B1 or Trunk C1 port of your choice
1 and 5–2).
5.3 GROUND START LINES
Using one pair twisted #24 AWG or #26 AWG jumper wire, cross-connect each ground
start C.O. line to the GTRK port of your choice
5.4 DID LINES
Using one pair twisted #24 AWG or #26 AWG jumper wire, cross-connect each DID
C.O. line to the DID card port of your choice
5.5 E & M TIE LINES
Using two pair twisted #24 AWG or #26 AWG jumper wire, cross-connect each E & M
tie line to the E & M card port of your choice
5.6 OFF PREMISE EXTENSIONS (OPX)
Using one pair twisted #24 AWG or #26 AWG jumper wire, cross-connect iDCS single
line extensions to telephone company OPX circuits
card are specifically designed to meet TELCO 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 single line stations on any other SLI card or a KDb-SLI requires the
installation of externally mounted protection devices.
