We have a Panasonic KX-TD1232C hybrid system, almost all of our terminals are digital.
We have 12 pairs running to a remote building, and we're supporting 4 terminals out there. Each terminal has two pairs. Due to construction, we need to support 4 more terminals, which exceeds the capacity of the wiring.
Obviously, we don't have to send a digital pair to the analog terminal, but do we need to send the analog pair to the digital terminals? The digital terminals appear to work without the analog pair, but are there any surprises waiting?
