? Remove the cover and both daughter boards from the PCM overvoltage module for easy access. ? Strip the cable to the appropriate length (it should be the inner edge of the clamp). Cut the sheath carefully with a wire-stripper. Avoid damaging the screen. Remove the sheath. ? Fold back the screen over the cable sheath. ? Strip the insulation from the pair cable and the conducting wires and cut them to the correct length. ? Guide the pairs through the strain relief clamps and connect them to the terminal block at the position for 120. ? Clamp the screen and the cable under the large strain relief clamp. ? Clamp the outer screen carefully under the relief clamp. ? Connect the prefabricated PCM-cable between the DF and the RBS. ? Re-insert the cards and put back the cover and tighten the screws.

OVP Module

?The rear daughter board slot must contain the OVP board. ?The forward card slot must be filled with one of the following daughter boards: ? Dummy board (loop forwarding; no processing function) ? Balun board (balances 75 to 120 ) ? By-pass relay board ? A combined bypass and balun board to convert an unbalanced system to a balanced system for the RBS, and to bypass an unbalanced system if the RBS is subjected to a power failure.
