IP-LQ: How does LQ-2W2 operate in RTS mode

Customer wanted to know how LQ-2W2 deals with RTS beltpacks / partyline systems

When LQ-2W2 is in RTS mode the audio from CH1 (pin 2) is put on Port A and CH 2 (pin 3) is put on Port B. Also the two XLR port jacks become parallel jacks so an RTS beltpack or com line can be plugged into either or both PL XLRS.
