Technical information
How many telephones can you have?
All items of equipment have a Ringer Equivalence Number (REN) which is used to calculate the
number of items that may be connected to any one telephone line. The BT Concero 1500 has a total
REN of 1, i.e. for a base and up to 5 handsets. Any other instrument provided by BT may be assumed
to have a REN of 1 unless stated otherwise.
A total REN of 4 is allowed per telephone line. If the total REN of 4 is exceeded, the telephone may
not ring. With different telephone types there is no guarantee of ringing, even when the REN is less
than 4.
