Using Bridge Clips
With Bridge Clips, the second leg of the punch-down block receives a
duplicate PBX signal from the first leg. The NGX is then connected to the
second leg of the punch-down block. Although it is not as flexible as the
Y-Splitter, this method is a viable means of passively tapping a PBX at the
punch-down block with the NGX. Bridge Clips are applied between the first
leg of the punch-down block to the second leg to duplicate the PBX signal
between the legs.
Using Bridge Clips limits you to wiring only one leg of the punch-down
block to the phones while the second leg must be dedicated entirely to the
NGX. Use this method only if the Y-Splitter method is not possible.
