Hello everyone,
maybe anyone knows how should be connected TN2185B board and external ISDN device? Official Avaya documentation said, that first port on board TN2185B are on pins 26, 1, 27 and 2. They named as "Term transmit Tip", "Term Transmit Ring", "Port transmit Tip" and "Port transmit Ring". The problem is that external ISDN device also have 4 pins, but they named as "TX+", "TX-", "RX+" and "RX-". How they shold be connected corretly?
