Technical information

How many telephones can you 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 other telephone line.
Your BT Relate 3000 has a REN of 1.5. A total REN of 4 is
allowed. 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.
