there are no port on the panle of PQ1, D75S(75ohm) or D12S/D12B(120ohm) will work with PQ1 to supply port. all these info can be found in document.

What's the "V5.2 signalling "Please describe it detail, I can't get your point.

is a connection protocol between Local exchange (LE) and an access network (AN) via E1 link.

i need to connect an old pstn switch to umg 8900 via OSN 7500 by two link E1 V5.2 connected to PQ1 card.
