Party Line Off-Hook Detection
The Model LE300-IP Line Extenders provide off-hook detection on the local Page/Party
®
system cable for
party lines 1 through 5. An off-hook condition means a handset station is in use. If multiple line extenders
are connected to the same Page/Party
®
system cable segment, only one off-hook detector can be enabled.
If connecting an LE300-IP to the same system cable segment as an ADVANCE Page/Party
®
Interface
(PPI) card, disable the LE300-IP off-hook detection for party lines 1 and 2. The PPI card contains off-
hook detection for party lines 1 and 2.
Several shorting clips (P6–P15) are used to enable the off-hook detection feature on party line 1 through 5.
Two shorting clips are associated with each party line and must be set to the same position for proper
operation. The party lines 1 through 5 are configured independently. Refer to Figure 6 for the location of
P6–P15 on the Main PCBA and Table 11 below for setting options.
