PART5. CONNECTING TELCO CIRCUITS

To limit the risk of personal injury, always follow these precautions before connecting TELCO

c i r c u i t s :

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 uninsulated telephone wires or terminals unless the telephone line has been

disconnected at the network interface.

d. Use caution when installing or modifying telephone lines.

Using one pair twisted #24 AWG or #26 AWG wire, cross-connect each loop start C.O line to the

trunk port of your choice (see Figures 5-1 and 5-2).

Using one pair twisted #24 AWG or #26 AWG wire, cross-connect any 2 SLI port to telephone

company OPX circuits (see Figure 5-5).

Circuits on the 2 SLI 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 C.O. line

circuits. Using single line stations on a EXP SLI or KDB SLI may cause damage to your equipment.

There is no special programming required for OPX use; however, it is suggested that the OPX ports

be set for data ports in MMC 208. The telephone company service facility interface code for OPX

circuits is OL13C.
