AT&T Release 2.0 manual Wiring

Connecting the Control Unit to the Network Interface

CAUTION:

■The telephone company is responsible for providing appropriate protection for central office trunks. Do not connect the central office trunks until you are certain that they are properly protected. See the section, “Central Office Trunk Protection,” in Chapter 2 for details.

■To avoid coupling power supply noise onto system wiring, allow at least 3 inches (8 cm) of clearance between the basic carrier’s power supply and any wiring or termination hardware located left of the control unit.

■If the network interface is greater than 25 ft (7.6 m) from the control unit, connect the control unit to the network interface using an off-premises range extender (OPRE)

See the documentation packaged with the OPRE for complete installation instructions

■If staples are used to attach the cords to walls or baseboards, check that the cords have not been pierced.

■National and local building codes specify the type of cable required for telecommunication wiring. For example, indoor wiring (DIW) cable cannot be used inside or on top of air plenums or ducts, along hot pipes, or across walkways. Consult your local ordinances and regulations for proper cable selection.

Wiring

The local telephone company should have already installed the network interface (the central office trunks). Before you install the system, verify that the network interface is the proper type and that it is located within 25 ft

(7.6 m) of the control unit. If the network interface is more than 25 ft (7.6 m) from the control unit, make sure you have an OPRE; see the caution above.
