NOTE

When changing from one protocol to another on a WPIM-RT1 that has been operational, save NONE as the protocol before changing to another protocol.

3.Use the arrow keys to highlight Timeslot View. Press the SPACE bar to select New, then press ENTER. The cursor moves to Timeslot #1 of the Timeslot Configuration Table.

The Next IF will increment as interfaces are added. The previously entered interfaces can be modified by entering the interface number.
