NOTE: Soldering is NOT
required. Use the supplied "Beanies," which can be crimped with
a pliers.

LOOP SERIES
WIRING (House Type) INSTALLATIONS:
NOTE: X indicates points in wiring where
filters may be placed.
Filters can be Hardwire or Modular.
We have 1 Line or 2 Line Modular Filters (2 or 4 wires).
A Hardwire Filter may be needed in
the middle of a cable run (X).
PARALLEL
DISTRIBUTION WIRING INSTALLATIONS:
NOTE: X indicates points in wiring where
Filters may be placed.
Filters can be Hardwire or Modular.
We have 1 Line or 2 Line Modular Filters (2 or 4 wires).

TWO LINE
TELEPHONE WIRING INSTALLATIONS:
NOTE: X indicates points in wiring where
Filters may be placed.
Filters can be Hardwire or Modular.

Two line telephones are treated similar to single line phones. Use 1
Line Modular Filters for each line individually, or use 2 Line Modular
Filters at the two line telephone set(s).
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 and
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.
ELECTRONIC
KEY SYSTEM / PBX WIRING:
NOTE: X indicates points in wiring where Filters may be placed.
Filters can be Hardwire or Modular.
We have 1 Line or 2 Line Modular Filters (2 or 4 wires).
D and 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 RJ-11 jacks supply single line phones, use 1 Line
Modular Filters.
When RJ-14 jacks supply two lines, use 2 Line 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.
