Technical information
How many telephones can you
have on the line?
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 Diverse 4000/4010 base
stations (with up to 6 handsets)
have a total REN of 1. 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. For example: if the
BT Diverse 4000 is used in
conjunction with three extension
telephones, each with a REN of 1,
then the total REN = 4.
Only use approved power supply
