If you connect too many telephones to your line they may
not ring correctly. To determine the number of telephones that
can be satisfactorily connected to your line, add together the
ringer equivalent numbers (RENs) of all the equipment you wish
to connect. If this number exceeds four, your telephones may not
ring. Your Link 904 telephone has an REN of one (1). BT
telephones have an REN of one unless otherwise marked.
