Although you may have any number of sockets, it is important to limit the number of telephones and other items of apparatus connected to the line by those sockets, to ensure that each telephone will ring. Every telephone or item of apparatus has a Ringer Equivalence Number (REN). In most cases a standard line should provide enough current for two or more telephones or items of apparatus, if then the RENs add up to no more than 4. Any telephone provided by BT may be assumed to have a REN of 1 unless otherwise stated on the base.
