Connecting To 4-Wire And Digital Matrix Intercom - ClearCom FreeSpeak II User Manual

This facility allows conferencing over a large area between a mix of beltpacks,
partyline stations and Eclipse system panels through an FS II Base station.
FS II beltpacks can only connect to a wired partyline via a wireless partyline.
Therefore in order to allow beltpacks to talk to each other and a wired partyline a
wireless partyline must be set up that includes the wired partyline (PLCHA or
PLCHB) and the beltpacks (see Figure 4-5 Connecting beltpacks to a wired
partyline). This ensures that the audio on the beltpacks is the talk audio and not
the sidetone audio.
