Party Line Off-hook Detection and Transmission
The Model LE200 Line Extenders provides off-hook detection on the local Page/Party
®
system cable for
party lines 1 through 5. Additionally, when an off-hook condition is detected, the LE200 transmits the
off-hook condition to the more remote LE200 so that it is duplicated on the remote Page/Party
®
system
cable. If multiple LE200s are connected to the same Page/Party
®
system cable segment, only one off-
hook detector may be enabled.
Several three-position headers and their shorting clips control party line 1 through 5 off-hook detection.
Both shorting clips associated with a particular party line must be set to the same position for proper
operation. The party lines 1-5 are configured independently.
