NOTE:

Install the 808A in a location that can be accessed only by authorized personnel. In addition, the location must meet standard environmental considerations such as temperature, humidity, and so forth.

6.Install the panel on any mounting frame in either a vertical or horizontal position. The housing has ears for screw-mounting and cutouts for snap-mounting the unit in an 89-type mounting bracket. Verify dial tone is present at each trunk circuit.

7.Locate the circuit start selection switches. See Figure 5-17. These are the first 10 two-position switches on the left side of the panel. They are used to set each of the 5 incoming trunk lines to either loop start or ground start.

Two switches are used for each circuit; switches 1 and 2 are used for circuit 1, switches 3 and 4 are used for circuit 2, and so forth. See Table 5-13. For loop start, set the switches to the left. For ground start, set the switches to the right.
