3. For each OC-48 line to be manually looped back, obtain a lightguide jumper
(package label FS1E-E-02) and a 20-dB loss lightguide buildout, or
equivalents. (It is possible to connect another LBO to an existing LBO to
obtain a total of 20-dB provided the LBOs do not physically interfere with the
shelf cover when closed.) Table A shows additional buildouts that are
available. Table B shows the buildout types that are compatible with different
codes of the REGENR circuit pack.
