Hi

Just wondering if anyone has installed one of these recently. Need to know if extensions are 2 wire or 4 wire. Or if any one has install manual handy. Seems pretty straight foward to install. Got one to do on saturday 20.02.10

It appears they are a maximum of 4 Extensions on a 4 wire.

I haven't seen one of these, but looking at the specifications it supports both the special feature phones and regular PSTN-type phones. The connection arrangements are probably very much like many digital PBX systems, i.e. one pair to provide the regular telephone loop plus one pair for the digital connection. In that case, you need a 2-pair connection to a jack for a feature phone, but only a 1-pair connection to any jack used for regular phone equipment.
