4.0INSTALLATION
Once the Model 1186 is properly configured, it is ready to connect to the fiber interface, to the G.703/G.704 equipment, and to the power source. This section describes how to make these connections.
The power, G.703/G.704 and Fiber Line connections are located on the rear panel of the Model 1186. Figure 5, below, shows the loca- tion of each of these ports.

4.1 CONNECT THE G.703/G.704 NETWORK
There are two ways to connect to the G.703/G.704 Network. This section describes both options. After selecting the appropriate connec- tion, set the internal jumpers as described in section 3.1.2 of this man- ual.
4.1.1 Connect Twisted Pair (120 Ohm) to G.703/G.704 Network
The Model 1186 is equipped with a single

4.2 CONNECT THE FIBER INTERFACE
The Model 1186 is designed to be connected to another Model 1186. The Model 1186 supports communication between G.703/G.704 equipment over one string of
