Hi, we have a UCM6102, with our two FXOs there is no input signal.
How does the pin assignment look at the FXO’s connections?
Here is a Vodafone PlusBox 340 to connect.
The plusBox has the following pin assignment to the PBX:
Pin1-Receive A (+) incoming
Pin2-TransmitA (+) outgoing
Pin3 Transmit B (-) outgoing
Pin4-Receive B (-) incoming
Thanks for the support
