Install the 808A Emergency Transfer panel

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.
Verify dial tone is present at each trunk circuit.
1
Locate the circuit start selection switches (see
2
page 216).
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
page 218.
3 For loop start, set the switches to the left. For ground start, set the switches to the right.
4 Connect a 25-pair cable between the male RJ21 25-pair connector on the Emergency
Transfer Panel and the yellow field of the Main Distribution Frame (MDF).
