General Information
Use the Model LE300 Series line extenders in pairs to extend the operating distance of Page/Party,
SmartSeries, or ICS Page/Party systems. Two Page/Party system cable segments connect through two,
line extenders using either a two-pair copper cable or fiber optic cable, depending on the distance
requirement. The local and remote cable segments are electrically isolated through the line extenders (see
Figure 1 for a typical block diagram).

Features
The Model LE300 Series Page/Party Line Extenders provide the following features between Page/Party
system cables:
•Page Line Audio Transmission—provides half-duplex page line audio transmission between two
Page/Party system cables.
•Page Line Audio Monitoring Output—provides a balanced 600-ohm audio output for both the local
and remote page lines.
•Page Line Audio Detect Output Contact—activates a contact closure whenever audio is detected on
the page line.
•Page Line FSK Data Transmission (SmartSeries Systems)—re-generates FSK (frequency shift
keying) data transmissions between two SmartSeries Page/Party system cables.
•Page Line 50 kHz VLC Transmission—re-generates the 50 kHz VLC (volume level control)
signals between two Page/Party system cables.
•Page Line Ground Fault Detection—detects ground faults on the page line of the local Page/Party
system cable.
•Page Line Ground Fault Re-generation—duplicates local Page/Party system cable ground faults to
remote LE300 line extenders.
•Page Line Ground Fault Output Contact—activates a relay contact whenever a ground fault is
detected on the local page line, remote page line, or both page lines.
•Party Line Audio Transmission—provides full duplex party line audio between two Page/Party
system cables for party lines one through five.
•Party Line Off-Hook Detection—provides off-hook detection on the local Page/Party system cable
for party lines one through five.
•Party Line Off-Hook Regeneration—transmits the off-hook condition to remote line extenders
when an off-hook handset station is detected.
•Audio Line Connection Relays—enables disconnection of the page line, party lines one through
five, and/or the page monitoring output connections from the main PCBA.
•Audio Line Muting—enables muting the page line and party lines one through five when they are
not physically connected to the line extender.
•Page/Party Line Balance—sets the line balance resistance on the page line and each of the five party
lines.
•Five Contact Closure Inputs and Relay Outputs (I/O)—enables activation of a remote line
extender output contact when the associated input contact on the local line extender activates.
•Echo Cancellation—performs an echo cancellation sequence on party lines one through five.

Audio Termination Connection Module
The conductors of the page line and party lines one through five of the Page/Party system cable connect to
the audio termination audio connection module. This board can also provide 33-ohm line balance
resistance required for the audio lines (see the Audio Functions section for information on the audio line
features).
