How many fax machines/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 PaperJet 40 has a REN of 1. A total REN of 4 is allowed. If the total REN of 4 is exceeded, the telephone may not ring.
With different fax/telephone types there is not guarantee of ringing, even when the REN is less than 4.
Switchboard compatibility
This product is intended for use within the UK for connection to public telephone network and compatible switchboards, which support tone dialling and timed break recall. If in doubt please consult your service provider.
Switchboard external line access code
