WARNING
The front cover is not hinged to the rear enclosure. When the cover bolts are
removed, the cover must be adequately supported.
1. While supporting the front cover, remove the ten cover bolts from the enclosure flange. Pull the front
cover far enough away to expose the internal connections and disconnect any wiring between the
front cover and rear enclosure. Place the front cover aside.
2. Connect the incoming subscriber line or the telephone line suppressor (if applicable) to TB1 on the
Main PCBA. See Figure 7.
