Installing the 808A Emergency Transfer Panel
Note:
Note:
The 808A must be installed in a location that can be accessed only by authorized
personnel. The location must meet standard environmental considerations such
as temperature, humidity, and so forth.
To install the 808A Emergency Transfer Panel:
1. Verify dial tone is present at each trunk circuit.
2. Locate the circuit start selection switches (see
Figure 47: 808A Emergency Transfer
Panel
on page 98).
These are the first 10 two-position switches on the left side of the Emergency Transfer
Panel. They are used to set each of the five 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 17: Trunk/test switches
on
page 101.
3. For loop start, set the switches to the left. For ground start, set the switches to the right.
