Partyline: Can I use two FIM-202s as standalone devices for linking 4-wire or 2-wire communications?

Question:  I have been asked to provide a remote Clear-Com interface for audio communication to a camera operator at a remote location. At this time all that is ran to that location is fiber optic cables. What options does Clear-Com offer?
Answer:  Using a Clear-Com EF-701M at each end of a FIM-202D set, you can extend Clear-Com or RTS 2-wire party-line intercoms over a fiber-optic link independent of a matrix intercom system.  The party-lines are linked by connecting the EF-701M to the FIM-202D using shielded CAT5 cable, plugging into the "CH1 Station" port on the FIM-202D and the “Matrix” port on the EF-701M. Set the Matrix/Direct switch (switch 1 on the rear of the EF-701M) to the up position and the CC/TW switch (switch 2) to the required position depending on party-line type.
Ensure that each pair of EF-701M units are connected to the same station ports on the FIM-202D interfaces i.e. CH1 Station to CH1 Station, CH2 Station to CH2 Station.  Both channels of the FIM-202D can be used allowing a second party-line to be extended using two more EF-701M units connecting to the second “CH2 Station” ports.
