3.7 Converting Analogue Partylines to HelixNet
Many Partyline installations use daisy-chained power terminal blocks to passively split analog
Partylines. This way of splitting works relatively well for one HelixNet Main Station. But because
the cable shielding through those blocks is not maintained, it makes the communication much
more sensitive to interference.
Also, crosstalk occurs if two or more Main Stations use terminal blocks that are close to each
other.
To maintain shield integrity, Clear-Com recommends that you:
Place existing terminal blocks in shielded and grounded enclosures
Or
Replace the terminal blocks with shielded and grounded XLR splitter boxes and XLR patch
panels.
