     The basic measurements made from the CO are usually the
DC resistance and AC impedance between tip, ring, and ground.
From this you can usually tell how things stand on the line.

     A standard ringer, as in a WE 600 phone (the "Traditional"),
draws "one Ringer Equivalence Unit".  The usual phone line
provides six Ringer Equivalence Units.  As long as you have
less than 6 REU on-line, the telco will be happy.  Most modern
phones draw less than one REU.  If you really have more than six
telephones, the central office will be undamaged but your phones
may not ring.  Some central offices may notice the problem, after which
they will probably try to sell you a small PBX and multiple lines.
