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 C12 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.
