Is this valid connection?
Phone2ndGen-(RJ45)-LS link adaptor-(LS link cable)-Icon600
That is not a valid connection method. The RJ45 on the phone is only for used with a 220. What you would need to do is use the link cable from the phone-->link adaptor-->cat 5 (150ft) or cat 6 (200ft)--link adaptor--link cable-->Icon 600.

Thank you very much for your reply.
I understood well.
I will tell our sales person who has much imagination no to sell such a combination!
