You don't say what the telephone problem is that you are
trying to solve....

Note that normal service is for an REN number of 5.

If you have 16 phones on a single line, that number might
be exceeded and stuff won't work right...phones won't ring.

If this is your problem, -- the phones don't ring -- then
go google " telephone REN" to read up on what I
am talking about....

If my post is redundant, please accept my apology...
