CONFIGURING A PARTY LINE
Before enabling a party line from the basestation’s front panel the type
of party line must be set on the basestation so that it can set the proper
termination, gain level, and call signalling for that system.
The three types of party line systems are: Clear-Com, Drake, and RTS.
To select the type of party-line system for a party-line port
1. Select PORTS from the main menu, then select PLCHA or PLCHB
from the AVAILABLE AUDIO port menu which appears.
2. The port configuration menu is displayed. Scroll rightwards to
display the second page of the menu.
3. Select TYPE. The first port type menu is displayed.

4. All the options on the first menu imply that the party line port will
have termination enabled. If this is correct select either Clear-Com,
Drake, or RTS. If the party line port should have termination
disabled because the party line is already terminated by another
device scroll rightwards to display the second party line type menu.

5. Select ‘OFF’ to disable party line termination on the port. This will
apply regardless of the type of party line connected to the port. For
example if the party line is connected to an MS-702 master station
with termination enabled the basestation termination must be
disabled.
6. The changes are saved and applied automatically five seconds after
the last time the setup/enter knob was pressed or turned. The
front-panel display flashes to indicate that the changes are being
saved and applied.
The basestation automatically sets the port’s termination, gain, and
call signalling options for the selected party line type.
To configure the noisegate for a party-line port
The noisegate sets a cutoff level below which audio input is ignored in
order to avoid transmitting low levels of background noise. The
noisegate can be set to a value in the range -70dB to -10dB when
enabled.
