General information

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 BT3110 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.
