Ringer Equivalence
REN is a guide to the maximum number of apparatus (for example, telephones) that can be simultaneously connected to one telephone line. The REN value of each apparatus is added together and must not exceed 4. Unless otherwise marked, a telephone can be assumed to have a REN of 1.0. Each modem on this unit has a ringer equivalence number (REN) of 4.0.
