Importance of Ringer Equivalence Number
The FCC regulation label includes the Ringer Equivalence Number (REN).
This number represents the electrical load applied to your telephone line after
you plug the PBX into the wall jack. The telephone line for your premises
does not operate correctly if the total ringer load exceeds the capability of the
telephone company’s Central Office (CO) equipment. If there are too many
ringers connected to the line, there may not be enough energy to ring your
system. If the ringer load exceeds the system’s capabilities, you may also
have problems dialing telephone numbers.
