Technical details
How many phones can I have?
All items of telephone equipment have a Ringer
Equivalence Number (REN), which is used to calculate
the number of items which may be connected to any
one telephone line. Your BT7660 has a REN of 1. A total
REN of 4 is allowed. If the total REN of 4 is exceeded,
the telephones may not ring. With different telephone
types there is no guarantee of ringing, even when the
REN is less than 4. Any additional handsets and chargers
that you register have a REN of 0.
