Placement at Jacks and Phones

A - Hardwire Filter breaking up the line in loop series wiring (like at houses).
B - Placement of Hardwire or Modular Filter at wall jack.
C - Hardwire or Modular Filter at line input to telephone.
D / E - Handset Filter blocking interference to the telephone when the handset cord intercepts the RFI. I've only seen location E needed once, so it will usually go at D.

Proper filter selection for the CO Lines on the KSU depends on wiring configurations.

When RJ11/RJ14 jacks supply single or two-line phones, use Modular Filters.

If the system is fed by an RJ-21X, use Hardwire Filters on each incoming line.

Our 2-Line Modular Filters are compatible with the stations side of electronic key telephone systems and PBXs.
