Technical information
How many telephones 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 BT
Synergy 4100 or 4500 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.
