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. The phone 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 are registered have a REN of 0.
